Answer:

≈5.20

Step-by-step explanation:

$x^{2} =27$

you are going to use the square root on both sides to cancel out the x^2

$\sqrt x^{2}=\sqrt 27$

find the square root of 27

x= about 5.20

you will have to round up when you see the actual result when you follow these steps

A plumber charges $60 for a service call, plus $40 per hour for any work completed. Which graph below shows the total amount the

alexdok [17]

using slope intercept equation

$\begin{gathered} y=mx+b \\ \text{where} \\ m=\text{slope} \\ b=y-\text{intercept} \end{gathered}$

Therefore, the equation is

$\begin{gathered} y=60+40x \\ x=\text{hour of work} \\ y=\text{charges in dollars} \\ y=40x+60 \end{gathered}$

let us test the x values to know the graph

$\begin{gathered} y=40x+60 \\ y=40(1)+60=100 \\ y=40(2)+60=140 \\ y=40(3)+60=180 \\ y=40(4)+60=220 \\ y=40(5)+60=260 \\ y=40(6)+60=300 \end{gathered}$

The answer is B

A box plot has 5 data descriptions. The correct option is 87 and 132.

<h3>How does a boxplot show the data points?</h3>

A box plot has 5 data descriptions.

The leftmost whisker shows the minimum value in the data.
The rightmost whisker shows the maximum value in the data.
The leftmost line in the box shows the first quartile.
The middle line shows the median, also called the second quartile.
The last line of the box shows the third quartile.

Since each quartile of the box-and-whisker plot represents 25% of the data. Therefore, values between which there are 3 quartiles present will represent 75% of the data.

Hence, the correct option is 87 and 132.

3x + 2y = -9<br> 4x - 2y = -26<br> please help I have to solve this with the elimination method

Paladinen [302]

Answer:

x = - 5, y = 3

Step-by-step explanation:

Given the 2 equations

3x + 2y = - 9 → (1)

4x - 2y = - 26 → (2)

Adding (1) and (2) term by term eliminates the y- term, that is

7x = - 35 ( divide both sides by 7 )

x = - 5

Substitute x = - 5 into either of the 2 equations and solve for y

Substituting into (1)

3(- 5) + 2y = - 9

- 15 + 2y = - 9 ( add 15 to both sides )

2y = 6 ( divide both sides by 2 )

y = 3
