Let f(x) be y so you have
y=7x-13
Reverse the signs of x and y so you have
x=7y-13
And then find the value of y
x+13=7y
(x+13)/7=y
And change y to f(x)-1

Use the diagram to determine the length LK. A) x2 + y2 B) x2 + y2 C) (x2 - x1)2 + (y2 - y1)2 D) (x2 - x1)2 + (y2 - y1)2
kherson [118]

Answer:

D. (x2 - x1)2 + (y2 - y1)2

Step-by-step explanation:

We can use the Pythagorean Theorem or Distance formula to solve this problem. JK = x2 - x1 and LJ = y2 - y1. To find LK, you square the two legs, add them together and take the square root. The solution is  

(x2 - x1)2 + (y2 - y1)2

∠xangle, x and \angle y∠yangle, y are supplementary angles. \angle y∠yangle, y measures 142^\circ142 ∘
lina2011 [118]

Answer:

Angle x = 38°

Step-by-step explanation:

It is important to note that:

Two angles are called supplementary when their measures add up to 180 degrees.

Angle x and y are supplementary

Angle y = 142°

Hence,

Angle x = 180° - 142°

Angle x = 38°
