Point c.

You can graph the two points in a calculator to find out the answer OR you can identify the lines using the y-intercept aka b in the y=mx+b format.

Y=x - 3 has a y-intercept of -3, so look for the line where it goes through -3 on the y axis. (do the same for the other except when the y-intercept is 1)

From this, you can identify the lines and just find where they intersect.

70=(4x+36)/2 figure this out please

adell [148]

Answer:

$\boxed{\bold{\huge{\boxed{x = 26}}}}$

Step-by-step explanation:

$70 = \frac{4x+36}{2}$

Multiplying both sides by 2

$70 * 2 = 4x+36$

$140 = 4x+36$

Subtracting 36 to both sides

$140 - 36 = 4x$

$104 = 4x$

Dividing both sides by 4

$26 = x$

$x = 26$

Which of the following are possible values of r? <img src="https://tex.z-dn.net/?f=%20%7Br%7D%5E%7B2%20%7D%20%20%3D%20%20%5Cf

Answer:

$r=\frac{\sqrt{3} }{4}$ and $r=-\frac{\sqrt{3} }{4}$

Step-by-step explanation:

when you solve for r in the given equation, you need to apply the square root property, which gives positive and negative answers (both should therefore be considered):

$r^2=\frac{3}{16} \\r=+/-\sqrt{\frac{3}{16}} \\r=+/-\frac{\sqrt{3} }{4}$

then you need to include these two possible solutions:

$r=\frac{\sqrt{3} }{4}$ and $r=-\frac{\sqrt{3} }{4}$

the table shows the number of cars washed and the amount earned by the car wash over several days. circle the number or term tha

TEA [102]

The first 3 rows are proportional

because when you divide the earning by car washed they all have the same unit rate of 9.5/ to answer the second part you multiply 9.5 by 88. you'll get $836

Find the values of x and y. Show your work pls (7x-4) (4y+8) 24 and 31

abruzzese [7]

Answer:

The value of x is 5.

The value of y is 4.

Step-by-step explanation:

From the figure, the lengths of the lines with equal number of markings are equal.

So, we will have the length of 7x - 4 = 31.

We solve for 'x'.

We get: 7x = 35

⇒ x = 5

Similarly, 4y + 8 = 24

⇒ 4y = 24 - 8

⇒ 4y = 16

⇒ y = 4

Therefore, the value of x = 5 and y = 4.

Hence, the answer.
