Answer:
Using the inverse composition rule you know that if (fog)=x and (gof)=x then the functions are inverses.

Answer:
Step-by-step explanation:
Equation of the line y = mx + c
The new line is perpendicular to 2x - 3y = -5
- 3y = - 5 - 2x
3y = 2x + 5
y =
Since the lines are perpendicular to each other : 
where
.
Slope of the given line

Slope of the new line

The equation to the new line passing through (-4, -3) and perpendicular to 2x - 3y = -5

Answer:
$569.50
Step-by-step explanation:
15% deduction from the initial price(100%) will have us remaining with 85%
100% = 670
85% = <u>85% x 670</u>
100%
= $569.50
