When you have the power multiplied to another power you have to multiply
so
(a^3)^3 - (b^3)^3 = a^9 - b^9
A is correct.
B is incorrect because when you multiply the exponents you get a^18 - b^18
C is incorrect because when you distribute the 2 you get a^6 - b^6
D is correct too
Answer:
Constant of proportionality is 190.
Step-by-step explanation:
To find proportionality constant we will find difference of weights after 2 days and at birth.

Now we will find difference of weights after 14 days and at birth. We will divide the difference by 14.


We can see that weights are increasing at a constant rate of 190 pounds per day. Therefore, our constant of proportionality is 190.
Answer:
11.) y-int:(0,1); x-int:(1,0)
12.) y-int:(0,8); x-int:(4,0)
13.) y-int:(0,-9); x-int:(-3,0)
14.) y-int:(0,-5); x-int:(-2.5,0)
Step-by-step explanation:
For each equation, first you have to graph it. Then to find the y-intercept, you mark and check where your line of your equation intersects the y-axis. To find the x-intercept, you mark and check where the line of your equation intersects the x-axis. The y-intercept always will have the coordinates of x=0 and the x-intercept always will have the coordinates of y=0.
