Answer:
- f⁻¹(x) = 1/7x² + 3
Step-by-step explanation:
<h3>Given</h3>- f(x) =
- Inverse of f(x)
<u>Change f(x) → x, and x → y, and solve for y:</u>
- x =
- x² = 7y - 21
- 7y = x² + 21
- y = 1/7x² + 3
<u>y = f⁻¹(x)</u>
- f⁻¹(x) = 1/7x² + 3
Answer:
The slope of FG is -1
Step-by-step explanation:
Given
Square EFGH
EF:
Required
Determine the slope of FG
First, we calculate the slope of EF
Make y the subject
The general equation has the form:
Where
Compare to
<em>From the name of the square EFGH, we can conclude that EF and FG are perpendicular</em>
<em />
The relationship between perpendicular lines is:
Where
-- Slope of EF
and
m2 = slope of FG
Substitute 1 for m1 in
<em>Hence, the slope of FG is -1</em>
