Exterior angle c = the sun of the two opposite interior angles a and b.

10x -23 = 5x -17 + 7x -26

Combine the right side:

10x -23 = 12x -43

Add 43 to both sides:

10x +20 = 12x

Subtract 10x from both sides:

20 = 2x

Divide both sides by 2

X = 10

Now you have x replace it in the equation for A:

A = 5x -27 = 5(10) -27 = 50-27 = 23

Angle A = 23 degrees.

Answer:

thats all i know so far. i dont know if you are adding or multiply but if adding then the answer is -647. if your multiplying then the answer is -5,651,100.

Step-by-step explanation:

A- (5x - 27)= -137

B-(7x - 26)= -182

C-(10x 23)= -230

HELP ASAP. Find the inverse of g(x)=1/3x-7 and find its domain and range

Find the inverse function of f.
f(x)=(1+3x)/(5-2x)
Interchange x and y to get:
x=(1+3y)/(5-2y)
Solve for y as follows:
5x-2xy=1+3y

3y+2xy=5x-1
y(3+2x)=5x-1
y=(5x-1)/(2x+3)

this is the inverse function

Find equations for those tangent lines to the graph of y = x − 3/x

pychu [463]

Step-by-step explanation:

y=X -3/X

y=X/1 -3/x

y= 2x -3/x

y*X= 2x-3

y*X/2 = x-3

Answer:

parallel

Step-by-step explanation:

3x = -2 - y will turn into y = -2 - 3x

4 + y = -3x + 1 will turn into y = -3 - 3x

so the lines will be next together (parallel)
