Answer:
f^-1(x) = 4x^2 -3 . . . . x ≤ 0
Step-by-step explanation:
Interchange x and y, then solve for y.
x = -1/2√(y+3)
-2x = √(y +3)
4x^2 = y +3
4x^2 -3 = y
Note that the range of the function f(x) is f(x) ≤ 0, so this will be the domain of the inverse function. Then the inverse function is ...
f^-1(x) = 4x^2 -3 . . . . for x ≤ 0
___
The attached graph shows this inverse function is a reflection of the function across the line y=x, as it should be.
Step-by-step explanation:
9 = a7 + b
-2 = a9 + b
b = 9-7a and b = - 2-9a
9 - 7a = - 2-9a
2a = - 11
a = - 5.5
b = 9 - 5.5*7 = - 29.5
y = -5.5x - 29.5

Answer: 9.7</h3>
======================================================
Explanation:
See the diagram below.
The diagram shows we have a right triangle with these side lengths:
- a = 8 meters
- b = 5.5 meters
- c = unknown hypotenuse
We'll use the pythagorean theorem to find c
Mrs. Durham and Brett are about 9.7 meters apart.
20 divided by 2 equal 10 and the rest are counting by twos please
