Answer:

Step-by-step explanation:

Complementary angles are two angles whose measures add to 90°.

m<CFD = 150° - 100° = 50°

m<EFD = 180° - 150° = 30°

Sum = 80°

m<AFB = 40°

m<DFE = m<EFD = 30°

Sum = 70°

m<AFC = 100°

Sum > 100°

m<BFC = 100° - 40° = 60°

m<DFE = 30°

Sum = 90°

Yes

-12 - (-5) = -7

-13 - (-5) = -8

-20 - (-4) = -16

-22 - (-11) = -11

10 - (-12) = 22

-3 - 2 = -5

-4 - 6 = -10

-5 - 5 = -10

0 - 6 = -6

Find the inverse of the function. Show work. <br> g(x)= - 3/x-2 +2

4vir4ik [10]

Answer:

$\displaystyle g^{-1}(x)=\frac{-7+2x}{x-2}$

Step-by-step explanation:

We are given the function:

$\displaystyle g(x)=-\frac{3}{x-2}+2$

Let's find the inverse of g.

Call y=g(x):

$\displaystyle y=-\frac{3}{x-2}+2$

We need to solve for x. Multiply both sides by x-2 to eliminate denominators:

$y(x-2)=-3+2(x-2)$

Operate:

$yx-2y=-3+2x-4$

Collect the x's to the left side and the rest to the right side of the equation:

$yx-2x=-3-4+2y$

Factor the left side and operate on the right side:

$x(y-2)=-7+2y$

Solve for x:

$\displaystyle x=\frac{-7+2y}{y-2}$

Interchange variables:

$\displaystyle y=\frac{-7+2x}{x-2}$

Call y as the inverse function:

$\boxed{\displaystyle g^{-1}(x)=\frac{-7+2x}{x-2}}$

1. What is the total cost of a $95.00 item with a sales tax of 6%?

Reptile [31]

Since the sales tax is 6%, the object will cost 1.06 (100% + 6%) times the original value.

1.06 × $95.00 = $100.70

The object will cost $100.70.

Let me know if you need any clarifications, thanks!
