Answer:

Step-by-step explanation:

1) group any number with an X together and rewrite answer (if there is a negative in front of a number always carry it with it when rearranging.)

10x-10x-6-2

2) lets solve the numbers with Xs together

10x+10x= 20x

3) now lets solve whole numbers

-6-2=-8

4) bring down the 20x and the -8/ rewrite problem with your solved numbers

20x-8

5) we have to have X alone so in order to get rid of the 20 in front of the X you must divide 20 by 20x,

20x/20 ( it cancel's out and now you're left with X)

X=-8

6) but whatever you do to one side of the equal sign you have to do to the other side so now you must divide -8/20 which will leave you with

Answer: X=-0.4 or -2/5

If the difference of a number and eight is tripled and the result is six more than the number, the number is 15

The difference of a number and eight is tripled, then the result is six more than the number.

Therefore, the number will be represented by a variable

let the number  = x

Hence,

3(x - 8) = x + 6

Therefore, let's open the bracket

3(x - 8) = x + 6

3x - 24 = x + 6

subtract x from both sides of the equation

3x - 24 = x + 6

3x - x - 24 = x - x + 6

2x  - 24 = 6

add 24 to both sides of the equation

2x  - 24 + 24 = 6 + 24

2x = 30

divide both sides by 2

x = 30 / 2

x = 15

Therefore, If the difference of a number and eight is tripled and the result is six more than the number, the number is 15

The slope of the graph is 20 and the y-intercept is -1050.

The slope of a linear graph is defined as the gradient of the graph .It is also defined by trigonometric properties as the tangent of the angle formed by the line with the positive y-axis.

The y-intercept is the point of intersection of the graph and the y-axis.

The general equation of a straight line in the cartesian plane is given by

y = m x + c where 'm' represents the slope and 'c' represents the y-intercept.

It is given that the one time editing cost is 1050 dollars.

Variable cost of printing each book = 15 dollars

Each book is sold at = 35 dollars

∴profit per book sold = 35 - 15 = 20 dollars

Let Gary sells x number of books . Profit from selling x books = 20 x

Let us consider the net profit of Gary after selling x books be represented by y.

∴ y = profit from x books - establishment cost

or, y = 20 x -1050

Now comparing the above equation with the general equation of a straight line( y = mx + c ) we  can infer that:

slope(m) = 20

y-intercept (c) = -1050

Therefore the slope of the graph is 20 and the y-intercept is -1050.

Yes, a statement with the word 'per' is always a unit rate;

When comparing two different kinds of numbers with distinct units, a rate is a ratio that is employed. The unit rate, on the other hand, shows how many units of one quantity are equal to one unit of another. When the rate's denominator is 1, we refer to the rate as a unit rate. In actuality, the amount included in each unit or per unit is referred to as the unit rate. Let's use some instances to help us grasp this:

Unit rate is 20 miles per hour, or 40 miles in two hours.

Answer:90

Step-by-step explanation:

you add 30 + 60 gives you 90 degrees

Using integrals, we have that:

a) The mean is of 1205 and the standard deviation is of 2.87.

b) P(1200 < X < 1202) = 0.2.

The distribution is given by:

f(x) = 0.1, 1200 < x < 1210.

The integral of this function will be used to find the probabilities.

The mean of the distribution is given by:

[tex]\mu = \int_{1200}^{1210} xf(x) dx[/tex]

Hence:

[tex]\mu = \int_{1200}^{1210} 0.1x dx [/tex]

[tex]\mu = 0.05x^2|_{x = 1200}^{x = 1210}[/tex]

Hence the mean is:

0.05(1210² - 1200²) = 1205.

The variance of the distribution is given by:

[tex]\sigma^2 = \int_{1200}^{1210} (x - \mu)^2 f(x) dx[/tex]

Hence:

[tex]\sigma^2 = \int_{1200}^{1210} 0.1(x - 1205)^2 dx[/tex]

[tex]\sigma^2 = 0.033(x - 1205)^3|_{x = 1200}^{x = 1210}[/tex]

[tex]\sigma^2 = 0.033(1210 - 1205)^3 - 0.033(1200 - 1205)^3[/tex]

[tex]\sigma^2 = 8.25[/tex]

The standard deviation is the square root of the variance, hence:

[tex]\sigma = \sqrt{8.25} = 2.87[/tex]

For item b, the probability is given by:

[tex]P(1196 < X < 1202) = \int_{1200}^{1202} 0.1 dx[/tex]

P(1196 < X < 1202) = 0.1x, from x = 1200 to x = 1202.

Applying the Fundamental Theorem of Calculus:

0.1(1202) - 0.1(1200) = 0.2.

The lower bound is of 1200 because the distribution is not defined for values less than 1200.

Hence:

P(1200 < X < 1202) = 0.2.

The range of the function on the graph containing all the real numbers greater than or equal to –3 . So the correct option is (d)

The collection of all a function's outputs constitutes its range.

The elements of the co-domain that are mapped are known as the images, while the elements of the domain are known as pre-images.

The set of all images of the domain's elements in this case serves as the function's range, as does the set of all of its outputs.

We have to find the function on the graph.

From the given graph, we can see from the graph that the function's maximum y value is -3 and that the graph keeps going up.

Therefore, the range includes all real values that are greater than or equal to -3.

Answer:

Step-by-step explanation:

Irrational numbers are those which cannot be expressed by the ratio of two integers.

A is rational because it is a recurring decimal. Recurring decimals can be represented by the ratio of two integers (this one can be represented by the fraction -2752/333, which is a ratio of two integers).

B is a fraction with two integers, therefore it is rational. -5/9 is a ratio of two integers.

C can be represented by 1747/100.

D is an infinite decimal but isn't recurring like A, meaning it cannot be represented by the ratio of two integers, and is therefore it is irrational, unless you are shown further digits of the decimal which prove it to be recurring, which is not the case here.

Multiply each side by 4 to get rid of the fraction

x * 1/4 *4 = 1.5 * 4

Larry Mitchell invested $7600 at 3% rate of interest and $11400 at 2% rate of interest.

In the field of finance, interest is the payment of a sum over and above the principal amount owed by a lender or depositor to a borrower or deposit-taking financial institution at a set rate.

Rate of an interest in defined as the amount that a lender charges a borrower in interest as a percentage of the principal.

Larry invested part of his $19000 at 3% and the rest at 2%

Let he invested $'x' at 3% interest .

Therefore amount invested at 2%=$(19000-x)

Interest earned annually at 3% on $x = [tex]\frac{3}{100} \times x =0.03x[/tex] .

Interest earned annually at 2% on $(19000-x)=[tex]\frac{2}{100} \times(19000-x)[/tex]

=[tex]380-0.02x[/tex]

Now the combined interest for both the investment is $560 .

Therefore we can form a linear equation to solve for x:

0.03x+380-0.02x=560

or, 0.01x=180

or, x=18000

Therefore Larry invested $18000 at 3% interest.

Money invested at 2%=$(19000-18000)=$1000

Hence Larry invested $18000 at 3% rate of interest and $1000 at 2% rate of interest.

The equations that are equivalent to the given equation are m - 4 = -7m - 8, -7m - 8 = m - 4 and -8 - 7m = m - 4

The equation is given as

-2m - 5m - 8 = 3 + (-7) + m

Remove the bracket

So, we have

-2m - 5m - 8 = 3 - 7 + m

Evaluate the like terms

So, we have

-7m - 8 = - 4 + m

The amount of bricks that Jack would need to complete the wall is 180.

The first step is to determine the total amount of bricks he would need to build the wall. In order to determine this value, ratio analysis would be used.

Total bricks needed = (area of wall x number of blocks already used) / (area of wall already built)

Area of wall = 8 x 1.5 = 12

Area of wall already built = 5 x 1.5 = 7.5

Total bricks needed = (12 x 300) / 7.5 = 400 bricks

Number of bricks needed to complete the wall = 400 - 300 = 180 bricks
