Answer:

y= (2/3)x -3

Step-by-step explanation:

M is equal to the slope in y=mx+b form. And the y intercept is equal to (0, -3), therefore the b part of the formula is -3.

Twice a number (z) added to 21 is equal to 9 times the number added to 7. What is the number?

pickupchik [31]

Answer:

The number is 2

Step-by-step explanation:

Twice a number (z) = 2*z = 2z

Twice a number (z) added to 21 = 2z + 21

9 times the number added to 7 = 9z + 7

9z + 7 = 2z + 21

Subtract 2z form both sides

9z - 2z + 7 = 21

7z + 7 = 21

Subtract 7 from both sides

7z = 21 - 7

7z = 14

Divide both sides by 7

z = 14/7

z = 2
