Answer:
y = -1
Step-by-step explanation:
When solving this equation use the distributive property and get...
-4 (y - 2) = 12
-4y + 8 = 12
-4y = 12 - 8
-4y = 4
y = -1

Step-by-step explanation:
Answer:
1) Clare's stone hit first.
2) 1 seconds.
3) Same maximum height for both.
4) 9 feet
Part A:
h = (-16t -8)(t - 1)
When the stone hits the water, the height will be 0
⇒ (-16t - 8)(t - 1) = 0
<u>set to zero</u>
⇒ -16t - 8 = 0, t - 1 = 0
<u>simplify</u>
⇒ t = -1/2, t = 1
So, time was 1 seconds for Clare and 1.25 seconds or Lin. Clare's hit first.
Part B:
For Lin's stone: maximum height: 9 feet.
For Clare stone: (-16(0.25) - 8)((0.25) - 1) = 9 feet
No both stone reached the maximum height of 9 feet.
Answer:
A. 160
Step-by-step explanation:
Supplementary angles add to be 180. Subtract 20 from 180 and you get 160.
Based on the given roots and their multiplicities, the function is made of the following factors:
f(x) = x (x + 3)^2 (x - 1) (x - 3)^2
The roots represent the point in the graph where they touch the x-axis. With the given condition that the function has a positive leading coefficient and is of even degree, the group of the function touches the x-axis at the roots and is curved upwards.
