Ben=x
Amy=x-24
x-24/x = 3/5
5x-120 = 3x
5x-3x = 120
2x=120
X= 60
Ben = 60
Amy = 60-24 = 36
Answer:
1) x=-1.5 , x=8 that is the answer
Answer:
(a) -5
Step-by-step explanation:
The vertical scale factor for the graph and the function can be found by comparing the y-value of a point on f(x) to the y-value of a point on g(x). The graph conveniently marks two corresponding points with these y-values:
f(-2) = 2
g(-2) = -10
The value of k in g(x)=k·f(x) is the ratio of these y-values:
k = g(-2)/f(-2) = -10/2 = -5
The value of the vertical scale factor k is -5.
-12x⁸y⁸ ÷ 3x⁴y².
Applying laws of indices. When you divide same base, you subtract the powers.
= (-12/3)x⁸⁻⁴y⁸⁻²
= -4x⁴y⁶
