You combine like terms so 5x + 3x= 8x and 2y + 4y = 6y so it is 8x + 6y
H= -1 here's why:
7 = 12 + 5h
First you subtract 12 from both sides then the equation would look like:
-5 = 5h
Then you would divide the equation by 5 from both sides it would then look like:
-1 = h

Answer:</h3>
29. e = D/(3f²)
30. k=-4, x=41 . . . . matches the 2nd selection
<h3>
Step-by-step explanation:</h3>
29. Multiply by the inverse of the coefficient of e. That coefficient is 3f², so you divide by that quantity.
... D = e(3f²)
... D/(3f²) = e . . . . . matches the first choice
___
30. You want to solve for k and use it with a different y-value.
... y = kx
... -96 = k·24
... -96/24 = k = -4
For y = -164, you have
... -164 = -4·x
... -164/-4 = x = 41
The coefficient of variation is -4, x is 41.
Answer:
6720
Step-by-step explanation:
Answer:
c 3/2
Step-by-step explanation:
4/3 x -5 = -3
Add 5 to each side
4/3 x -5+5 = -3+5
4/3 x = 2
Multiply each side by 3/4 to isolate x
4/3 *3/4 x =2 *3/4
x = 6/4
Simplifying
x = 3/2
