Answer: f^-1(x) = (y - 7)/11
Explanation:
f(x) = 11x + 7
y = 11x + 7
y - 7 = 11x
(y - 7)/11 = x

Answer:
C
Step-by-step explanation:
2.88*2.2=6.336, which is approximately 6.34.
Answer:
A
Step-by-step explanation:
49y² - x² ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , then
49y² - x²
= (7y)² - x²
= (7y - x )(7y + x) → A
Using the distributive property, you’ll get the equation 56i+63.
You’ll distribute (multiply) 7 to 8i, and 7 to 9
