Answer:
6(y + 4) = -3(2y - 2) + 8y
6y + 24 = -6y + 6 + 8y
6y + 24 = 2y + 6
Subtract -2y on both sides
4y + 24 = 6
Subtract -24 on both sides
4y = -18
y = - 4.5
Answer:
Unit
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:
4x and 7x
–3 and 1
Step-by-step explanation:
4x-3+7x+1
4x, 7x are like terms because the both have an x
-3,1 are like terms because they are both constants
4x+7x-3+1
11x -2
