Answer:
Using the equation y = abx , substitute both of your given points into that equation.
2 = ab2 and 4 = ab3 Solve each equation for a.
2⁄b2 and 4⁄b3 = a Therefore, 2⁄b2 = 4⁄b3
Cross multiply: 2b3 = 4b2 Divide both sides by b2
2b = 4 a = 2/4 = 1/2
b = 2
y = 1 (2)x

Answer:
7.5 or 15/2
Step-by-step explanation:
x-3x+6=2x-24 -- Combine like terms
-2x+6=2x-24 -- Add 2x to each side
6 = 4x-24 -- add 24 to each side
30 = 4x -- divide by 4
15/2 or 7.5 = x
Add the numbers at the top of each bar (some numbers you have to guess at). you come up with around 380 to 390. closest answer is B, 388
