Answer:
-4/5
Step-by-step explanation:
Slope equation. Take 2 points from the graph and put them into this equation:
y2 and x2 are the second point on the graph (5, -1) and vice versa.
Step-by-step explanation:
y = x² - 16
x² = y + 16
x = sqrt(y + 16) because x is non-negative.
Hence the inverse function is f^(-1)(x) = sqrt(x + 16). (A)
A- 10.5
B- 5.25
is what the answers are
5/45, 6/54, 7/63
Any 2 numbers that you divide and have the ratio 1:9
