3x+8.5 =2.5x + 14.5
subtract 2.5x from each side
.5x + 8.5 = 14.5
subtract 8.5 from each side
.5x =6
multiply by 2
x =12
at 12 weeks they will be the same height
Choice B
Answer:
The value of k would be 4
Step-by-step explanation:
If f(x) is shifted vertically k unit upward then,
Transformed function is,
g(x) = f(x) + k,
Using the given graph,
line f(x) passes through (0, -3)
line g(x) passes through (0, 1)
Difference in y-coordinate = 1 - (-3) = 1 + 3 = 4
∵ y-coordinate represents the vertical shifting,
So, g(x) = f(x) + 4,
Hence, the value of k would be 4.
