[A+7= 28] is the correct equation I believe, though I may be wrong.
Answer:
400 (Sorry if its wrong.)
Step-by-step explanation:
50×3=150
5×40= 200
150+200= 350
350+50=400
Answer:
Line A
Step-by-step explanation:
Line A has a constant of proportionality (slope) of 4.
Answer:
It's choice B.
Step-by-step explanation:
Let's look the one you have chosen (A):
f(x) = x - 2/ 7 + 8
x-2 / 7 = f(x) - 8
x- 2 = 7(f(x) - 8)
x = 7(f(x) - 8) + 2
The inverse)= 7(x - 8) + 2
So it's not A.
B. f(x) = 5(x/4) - 3
5x / 4 = f(x) + 3
5x = 4(f(x) + 3)
x = 4(f(x) + 3 / 5
So the inverse is 4(x + 3) / 5
So it is B.
