Given system of equations

3x - 8y = 11 ______________________1

2y + x = 13 ______________________ 2

Use the substution method

How to use the substitution method

1. pick one of the equation

2. make one of the variable subject of relation

3. substitute

From equation (1)

2y + x = 13

x = 13 - 2y

substitute x from equation 1 to 2.

3(13 - 2y) - 8y = 11

39 - 6y - 8y = 11

39 - 11 = 6y + 8y

28 = 14y

y = 28/14

y = 2

Next, substitute y in equation 2 to find x.

x = 13 - 2y

x = 13 - 2(2)

x = 13 - 4

x = 9

Final answer x = 9

we can assume the lines are parallels so both triangles will have equal angles, so:

s=55° and p=x

now if we add 110 and x, we have a line this means

110+x=180

x=180-100

x=80

so p=x=80

and finally, the angles inside a triangle must add 180° so

55+p+t=180

55+80+t=180

135+t=180

t=180-135=45

So the answer is:

p=80°

s=55°

t=45°

Solution:

In the given figures, angles of the triangle ABC are corresponding equal to triangle DEF and the sides are proportional to each other.

Thus, the triangle ABC is similar to triangle DEF.

Therefore, the relationship between both triangles is the proportional side lengths.

Both triangles are not of the same size as their sides are not equal.

Both triangles are also not congruent as they do not satisfy any five conditions of congruence.

Hence, the correct option is A.

3 combinations:

3 quarters and 6 dimes

5 quarters and 1 dime

1 quarter and 11 dimes

1) Remember that a dime corresponds to $0.10 and a quarter to $0.25. And the value we want to find is $1.35

2) As we can see the last digit on $1.35 is 5 then we can infer that we're going to need an odd number of quarters ($0.25). Also, notice that we need whole numbers for the quantities of each coin. In other words, multiples of 0.10 and 0.25 whose sum yields to $1.35. So let's do it step by step:

So, we can write out the following list of combinations:

q (quarter) 3 q = 3 x 0.25 = $ 0.75

d (dimes) 6 d = 6 x 0.10 = $ 0.60

0.60 + 0.75 = 1.35

2.2) Another possible combination:

q (quarter) 5 q = 5 x 0.25 = $ 1.25

d (dimes) 1 d = 1 x 0.10 = $ 0.10

0.10+1.25= 1.35

2.3)

q (quarter) 1 q = 1 x 0.25 = $ 0.25

d (dimes) 11 d = 11x 0.10 = $ 1.10

0.25+1.10 = 1.35

3) Hence, considering that we need to combine dimes and quarters and their sum must be lesser than $1.35 We have three combinations with whole numbers of dimes and quarters:

3 quarters and 6 dimes

5 quarters and 1 dime

1 quarter and 11 dimes

Using factor theorem to solve the equation below:

For this problem, we are given a parallelogram with a diagonal drawn, inside it there are markings for a few angles. We need to determine the unknown angles.

Opposite sides of a parallelogram are parallel, this means we can treat the diagonal as a transversal line that crosses two parallel lines. Since this is the case, the angles 33º and xº are alternate interior angles and have the same length:

The opposite angles in a parallelogram are congruent, therefore:

The sum of internal angles is 360º, therefore we have:

The value of x is 33º, the value of y is 38º and the value of z is 109º.

Answer:

Assuming you're trying to find where the lines intersect (their solution), the point where they intersect is (1/2 , 1).

Step-by-step explanation:

When you are trying to find the point where two lines intersect, you have to find the x and y values of that point. To do that, just set the lines equal to each other.

First, since y must equal y:

y = y

-4x + 3 = 4x - 1

Now solve for x:

-8x + 3 = -4

-8x = -4

8x = 4

x = 1/2

We just found the x value of the shared point. Now we need to find the y value of that point. Again, since the two lines share this point, plugging in the x value will result in the same y value for both lines.

So just plug in x to any of the equations: (I think y=4x-1 is easier)

y(1/2) = 4(1/2) - 1     or      y = 4(1/2) - 1  (it doesn't matter how you write it)

y(1/2) = 2 - 1           or      y = 2 - 1

y(1/2) = 1

So the point is:

(1/2 , 1)

To check you can plug in the y value you find, 1 in this case, and solve for x. If you get the same x value as before, everything is correct.

So:

(1) = -4x + 3

-2 = -4x

1/2 = x    or    x = 1/2

Great! Everything is correct.

This may seem like a very long process, but it is very easy. Just find the x and y values that the lines share by setting the lines equal to each other.

Using functions, it is found that:

a. The costs for two years are as follows:

b. The pros and cons are as follows:

The cost of $2,600 for the first year is obtained as follows:

For the second year, only the hourly cost will be paid, hence $2,000 will be added and the total cost is of:

$2,600 + $2,000 = $4,600.

The pros of Option A are the lower initial fees, hence for a lower number of hour, the cost is smaller, while the con is the high hourly price, meaning that for a high number of hours, option B is better.

The cost of $2,600 for the first year is obtained as follows:

For the second year, only the hosting fee is paid, meaning that $360 is added to the cost, thus:

$1,360 + $360 = $1,720.

The pros and cons are basically opposite of option A, higher basic fees with lower hourly/monthly fees, meaning that it is better over longer periods.

ANSWER and EXPLANATION

We want to sketch the graph of the given function:

First, we have to check for the asymptotes of the function.

To find the vertical asymptote, we have to equate the denominator to 0 and solve for x:

That is the vertical asymptote.

To find the horizontal asymptote, we have to check the degrees of the numerator and denominator. Since the degree of the numerator is greater than the denominator's, there is no horizontal asymptote.

To find the slant asymptote, divide the numerator by the denominator and identify the quotient:

This implies that the slant asymptote is:

The asymptotes will provide the boundaries for the graph of the function as follows:

Now, we have to find some coordinate points that satisfy the function.

Let us solve for y for values of x = -2, -1, 0, 1, 2, 3:

We also have to identify the x and y intercepts of the function.

For the x-intercept, solve for x when y = 0:

For the y-intercept, solve for y when x = 0:

Let us draw the table of values:

Now, we can use the calculated points, the intercepts, and the asymptotes to sketch the graph of the function:

That is the sketch of the function.

Answer:

a) degree 5; monomial

b) degree 7; polynomial

c) degree 3; polynomial

d) degree 2; polynomial

e) degree 3 polynomial

Explanation.

A polynomial is a mathematical expression containing coefficients and variables.

An example of a polynomial is 42x^5 + 23 x^3 - 2x.

A monomial is a polynomial that contains only one term. For example, x^4, 34x^5, 2x, etc.

Having that in mind, we go through the expressions and place them in one of either category.

a) 7^5

This contains only one term, meaning it is monomial; its highest exponent is 5, meaning it is of degree 5.

b) 5^7 + 7^2

This contains two terms, meaning it is a polynomial; its highest exponent is 7, meaning its degree is 7.

c) 7^3 + 11^2 − 13 + 112

This expression contains four terms - it is a polynomial; its highest exponent is 3, meaning its degree is 3.

d) + 2 + 3^2

This contains three terms, meaning it is a polynomial; its highest exponent is 2, meaning its degree is 2.

e) 11^3 − 7^3

This contains 2 terms, meaning it is a polynomial; its highest exponent is 3, meaning it is of degree 2.

Last year, Susan had $20,000 to invest. She invested some of it in an account that paid 10% simple interest per year, and she invested the rest in an account that paid 7% simple interest per year. After one year, she received a total of $1790 in interest. How much did she invest in each account?

Let

x ------> amount invested in an account that paid 10% simple interest per year

20,000-x ------> amount invested in an account that paid 7% simple interest per year

so

The formula of simple interest is equal to

I=P(rt)

In this problem we have that

10%=0.10

7%=0.07

x*(0.1)+(20,000-x)*(0.07)=1,790

solve for x

0.10x+1,400-0.07x=1,790

0.03x=1,790-1,400

0.03x=390

x=$13,000

therefore

We have the equation:

We have to find the amplitude, the period, the horizontal shift and the midline.

The amplitude can be calculated as half the difference between the maximum and minimum value of the function.

The maximum value will happen when the sine is equal to 1 and the minimum when the sine is equal to -1.

We can then calculate the amplitude A as:

Now we have to calculate the period.

The period will be equal to the horizontal distance at which the function starts repeating itself (or complete a period).

As we have a sine function we know that:

That means that it will repeat itself for any multiple of 2π.

We can calculate the period as:

The period is π.

The horizontal shift will be given by the constant value inside the argument of the sine function. We can ignore the other terms and factors and use only the sine function in this case.

For example, for sin(2x) = 0, this value corresponds to x = 0.

In the case of sin(2x-10) = 0 this corresponds to an x that is 5.

That is because the function has a frequency that is twice as the frequency of the hpure sine function.

If the function wasn't periodice we would see it translated by 10 to the right.

We can calculate the midline as the average of the function.

This average value will be given by the average value of the sine function, which is 0, so we can calculate the midline as:

Answer:

The amplitude is 6.

The period is π.

The horizontal shift is 10 units to the right.

The midline is y = 3.

b. The value of (3.6 × 10^-5) ÷ (1.8 × 10^2) is 2 × 10^-3. This illustrates the concept of standard form.

The standard form is simply used in Mathematics to illustrate the numbers that are either too large or too small.

It's important to note that the multiplication of exponents is an addition and the division of the power is subtraction.

Therefore, (2.3 × 10⁴) × (1.5 × 10^-2) will be:

= (2.3 × 1.5) × (10^(4-2)

= 3.45 × 10^2
