zvonat [6]

Answer:

$7.50

Step-by-step explanation:

3 hours + 5 hours = 8 hours

8 hours = $85 (total) - $25 (allowance)

1 hour = $60 ÷ 8 (hours he worked)

1 hour = $7.50

What is the inverse of f(x)=(-2x+2)/(x+7)?
Nana76 [90]

By applying the concept of the inverse of a function and <em>algebraic</em> handling, we conclude that the inverse of f(x) = (- 2 · x + 2)/(x + 7) is g(x) = (- 7 · x + 2)/(x + 2).

<h3>How to find the inverse of a function</h3>

In this question we have a <em>rational</em> function f(x) and finding its inverse consists in clearing x in terms of f(x). Prior any algebraic handling, we need to apply the following substitutions:

x \to y

f(x) \to x

x = \frac{-2\cdot y + 2}{y+7}

x · (y + 7) = - 2 · y + 2

x · y + 7 · x = - 2 · y + 2

2 · y + x · y = - 7 · x + 2

y · (2 + x) = - 7 · x + 2

g(x) = \frac{- 7\cdot x + 2}{x + 2}

By applying the concept of the inverse of a function and <em>algebraic</em> handling, we conclude that the inverse of f(x) = (- 2 · x + 2)/(x + 7) is g(x) = (- 7 · x + 2)/(x + 2).

Geometry B: fill in the blank
olga_2 [115]

Answer:

The circumference of a circle is the distance around the entire circle, while arc length, s, is the distance <u>between</u> two points on the circle.

C = 2πr = 2π( <u>5</u><u> </u>) = 10π ≈ 31.4 units

3.14 is an approximation for π.

s = θ/360° (C)

mAB = 60°/360° ( 31.4)

= <u>1</u><u>/</u><u>6</u>(31.4) ≈5.2 units
