Answer: y = (-2/3)x + (4/9)

Step-by-step explanation:

y = mx + b is the form expected

-18y + 8 = 12x

subtract 8 from both sides

-18y = 12x - 8

divide both sides by -18

y = (12x/-18) - (8/-18)

Simplify the negatives and pull x out of the parenthesis (this only works if x is in the numerator).

y = (-12/18)x + 8/18

Simplify the fractions

y = (-2/3)x + 4/9

Answer:

The required value of y is,

Step-by-step explanation:

Given equation,

→ -18y + 8 = 12x

The slope-intercept form is,

→ y = mx + b

Let's rewrite the equation,

→ y = mx + b

→ -18y + 8 = 12x

→ -18y = 12x - 8

→ -y = (12x - 8)/18

→ -y = (2/3)x - (4/9)

→ y = -(2/3)x + (4/9)

Hence, this is the answer.

The lines are not intersecting. The system of linear equations has a solution only if the lines corresponding to the equations intersect.

The general linear equation is,

y=mx+c, where m is the slope.

The slopes of lines m=2.

Since the graphs are parallel or have the same slope and will never intersect, the system of linear equations have no solution.

The limit of a function is the value that a function approaches as that function's inputs get closer and closer to some number.

The question asks us to estimate from the table:

To find the limit of g(x) as x tends to -2, we need to check the trend of the function as we head towards -2 from both negative and positive infinity.

From negative infinity, the closest value we can get to before -2 is -2.001 according to the values given in the table. The value of g(x) from the table is:

From positive infinity, the closest value we can get to before -2 is -1.999 according to the values given in the table. The value of g(x) from the table is:

From the options, the closest estimate for the limit is 8.03.

The correct option is the SECOND OPTION.

LA rectangle has two pairs of sides of the same length. If we call W to the width of the rectangle, we know that the length is 6cm more. If we call L the length of the rectangle:

The perimeter of a rectangle is twice the length plus twice the width:

Since we know that the perimeter is 52 cm, we can write the system of equations:

We can substitute the first equation into the second one:

And solve:

We know that W = 10cm, we can now find L:

Answer:

The distance from the edge of the fountain to the centre is approximately 23.87 inches.

The water fountain forms a circle. The distance around the water fountain is the circumference of the circle formed.

Therefore,

circumference = 2πr

150 = 2πr

The distance from the edge of the fountain to the centre is the radius of the circle formed. Therefore,

75 = πr

r = 75 / 3.14159

r = 23.8732616287

r = 23.87 inches

The distance from the edge of the fountain to the centre is approximately 23.87 inches.

A system of equations is consistent if the system has a solution and it is inconsistent if it has no solution.

Since the lines intersect at a point, the system has a solution and the solution is unique.

If a system has a unique solution, then the system is independent.

Therefore, the given system of equations is consistent and independent. It has a unique solution.

- The amount a person is paid per hour in wages is the amount that the person collects for every hour that he works

- Let us imagine that a person receives $a for every hour worked.

- This means that:

After 1 hour, the person makes $a

After 2 hours, the person makes $a + $a = $2a

After 3 hours, the person makes $a + $a +$a = $3a

- We can therefore generalize as follows:

Thus, after x hours, the person makes:

Intersecting Lines

When two lines intersect, four angles are formed at the point of intersection.

Two pairs of angles are vertical, i.e., they have the same measure.

Two pairs of angles are complementary (or linear) therefore their sum adds up to 180°.

We are given one of the angles that has a measure of 67°.

Then, another angle also measures 67° (the vertical peer).

One of the other angles is 180° - 67° = 113°

The other angle also measures 113° (the other vertical peer).

According to the facts found above, the following statements are true:

* Vertical angles are congruent, therefore another angle must equal 67°

* The lines form linear pairs

* The lines form complementary angles

* Two of the angles formed measure 113°

* Two of the angles formed will have a sum of 180°

Note: The last statement should read "Two pairs of angles formed..."

Answer:

The interval at which the function is increasing is from x = -2 to x = 0. In interval notation, it is (-2, 0).

Explanation:

See the graph below for the pattern of the function.

As you can see above, from x = -∞ until x = -2, the value of the function decreases from y = +∞ to y = -7.

Then, starting at x = -2 to x = 0, the value of the function increases from y = -7 to y = -3.

Lastly, starting at x = 0 to +∞, the value of the function decreases again from y = -3 to -∞.

Hence, the interval at which the function is increasing is at (-2, 0).

Simple interest is represented by the following expression:

We need to create a system of equations:

Let x be the money invested in the account that paid 6%

Let y be the money invested in the account that paid 10%

So, he received a total of $920 in interest, then:

And we know that money invested must add together $10,000:

Then, we can isolate y in equation (2):

Now, let's substitute y=10,000-x in the equation (1):

That means, he invested $2,000 in the account that paid 6% simple interest. Now, having x, we are going to substitute x in the second equation (2):

He invested $8,000 in the account that paid 10% simple interest per year.

Answer:

11.2 Slices / Week

Step-by-step explanation:

We know that Jake has eaten 5 slices of cake in 3 days. You can divide 5 / 3 to get an average of 1.6 slices of cake being eaten per day. The question asks what the weekly rate or eating the cake will be, do you need to multiple 1.6 x 7 for the total amount of cake eaten per week, which is 11.2 slices!

Answer:

11.6

explanation

we have 7 days.

7days-3days =4

in 3 days he has eaten 5 slices

again 4-3 days=1

so in 6 days he has eaten 10 slices

we have 1 day left.so if he eats 5 slices in 3 day,how many he eat slices in 1 day?5/3=1.6

10+1.6=11.6

we know that

AS we can note , the hypotenuse is twice as long as the shorter leg. Additionally, the longer leg is square root of 3 tines as long as the shorter leg. Therefore, the answer is option C and F

To answer this question, we need to use the next formula for compound interest:

From the formula, we have:

• A is the accrued amount. In this case, A = $7900.

• P is the principal amount. In this case, $4500.

• r is the interest rate. In this case, we have 4.7%. We know that this is equivalent to 4.7/100.

• n is the number of times per year compounded. In this case, we have that n = 365, since the amount is compounded daily.

Now, we can substitute each of the corresponding values into the formula as follows:

And we need to solve for t to find the number of years, as follows:

1. Divide both sides by 4500:

2. Applying natural logarithms to both sides (we can also apply common logarithms):

3. Then, we have:

4. And now, we have to divide both sides by 365:

If we round the answer to two decimals, we have that t is equal to 11.97 years.

The single trig function that simplifies the function is sec(t)

Trigonometry deals with the functions of angles and how they're applied.

Given cot(t)/csc(t)-sin(t)

since csc(t) =  1/sin(t) , we have:

[tex]\frac{ cot(t)}{csc(t)-sin(t)} = \frac{cot(t)}{\frac{1}{sin(t)} - sin(t) }[/tex]

[tex]\frac{ cot(t)}{csc(t)-sin(t)} = \frac{cot(t)}{\frac{1-sin^{2}(t) }{sin(t)} }[/tex]

since:

cos²(t) = 1 - sin²(t)

Therefore we have:

cot(t) / csc(t)-sin(t) = cot(t)/ cos²(t)/sin(t)

cot(t) / csc(t)-sin(t) = cot(t) / cos(t).cos(t)/sin(t)

Since  cos(t) / sin(t) = 1/tan(t) = cot(t)

Therefore:

cot(t) / csc(t)-sin(t) = cot(t)/ cot(t)×cos(t)

cot(t) / csc(t)-sin(t) = 1/cos(t)

Since   1/cost = sec(t)

Finally, cot(t) / csc(t)-sin(t) is sec(t).
