Answer:

Step-by-step explanation:

The f^-1 notation indicates you need to find the inverse of the function

y=2x+1

x=2y+1

Exchange the x & y variables. Note this is what accomplishes that reflection across the line y = x

7=2y+1

-2y=1-7

-2y=-6

Divide both side of the equation by -2

negative divide negative is positive so

y=3

8. In AABC, LA is a right angle and mzB = 45°. Find BC.

Margaret [11]

Answer:

BC = 11 $\sqrt{2}$

Step-by-step explanation:

using the sine ratio in the right triangle and the exact value

sin45° = $\frac{1}{\sqrt{2} }$ , then

sin 45° = $\frac{opposite}{hypotenuse}$ = $\frac{AC}{BC}$ = $\frac{11}{BC}$ = $\frac{1}{\sqrt{2} }$ ( cross- multiply )

BC = 11 $\sqrt{2}$
