Slope-intercept form is y = mx + b, and m is the slope
Because the slope is -3, m = -3
y = -3x + b
Plug in the point and solve for b
-7 = -3(-3) + b
-7 = 9 + b
-16 = b
a. y = -3x -16
Answer: option a.
Step-by-step explanation:
Given the expression 
, you need to remember:
The Product of powers property:
The Power of a power property:
And:
![\sqrt[n]{a^n}=a](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%5En%7D%3Da)
Therefore, as the index of the radical is 2, you can rewrite 
as:
Rewrite this and simplify. Then:
This matches with the option a.

Answer:
18 t-shirts.
Step-by-step explanation:
Trey made a total profit $106 by selling t-shirts and hats. $34 of that profit was from selling hats, subtract 34 from 106 and you will get 72. So he made a profit of $72 in selling t-shirts. The t-shirts were $4 each, so if you divide 72 by 4 you will get 18. Meaning he sold 18 shirts.
