Find the slope of 9x=3y+5

1 answer:

4 0

9x = 3y + 5
9 9
x = 1/3y + 5/9
x - 5/9 = 1/3y + 5/9 - 5/9
x - 5/9 = 1/3y
3(x - 5/9) = 1/3y · 3
3x - 1 2/3 = y
y = 3x - 1 2/3

Given (x – 7)2 = 36, select the values of x.

aksik [14]

Answer:

x=1,13

Step-by-step explanation:

(x – 7)^2 = 36

Take the square root of each side

sqrt((x – 7)^2) = sqrt(36)

x-7 = ±6

x-7 = 6 x-7 =-6

Add 7 to all sides

x-7+7 = 6+7 x-7+7 = -6+7

x = 13 x=1

x = 502.5

Therefore, the original price is $502.5

Answer:

Her solution is incorrect. The correct solution for the equation is x=7

Step-by-step explanation:

Sasha solved the equation incorrectly.

The correct way to solve this equation would be:

8x = 56

Divide both sides by 8.

$\frac{8x}{8}= \frac{56}{8}$

You would get x=7.

This equation has 1 solution.

Hope this helps! Please let me know if you need more help, or if you think my answer is incorrect. Brainliest would be MUCH appreciated. Have a great day!
