Answer:
- <em>To solve these first swap x and y, solve for y and name it inverse function</em>
3. <u>y = -8x + 2</u>
- x = -8y + 2
- 8y = -x + 2
- y = -x/8 + 2/8
- y = -(18)x + 1/4
f⁻¹(x) = -(18)x + 1/4
-----------------------------------------
4.<u> y = (2/3)x - 5</u>
- x = (2/3)y - 5
- (2/3)y = x + 5
- y = (3/2)x + (3/2)5
- y = 1.5x + 7.5
f⁻¹(x) = 1.5x + 7.5
-----------------------------------------
5. <u>f(x) = 2x² - 6</u>
- x = 2y² - 6
- 2y² = x + 6
- y² = 1/2x + 3
- y =
f⁻¹(x) =
-----------------------------------------
6. <u>y = (x - 3)²</u>
- x = (y - 3)²
= y - 3- y = 3 +
f⁻¹(x) = 3 +

Answer:
- 3.04 m
- 18
Step-by-step explanation:
The midsegment of a triangle is half the length of the side it is parallel to.
1. For a distance of 6.08 m between wall plates, the colar tie will be half that, or 3.04 m.
2. The perimeter of ΔXYZ is ...
... 10 + 12 + 14 = 36
The sides of ΔABC are half the length of the sides of ΔXYZ, so the perimeter of ΔABC is half the perimeter of ΔXYZ.
... perimeter of ΔABC = 36/2 = 18
