I DONT UNDERSTAND HELP <br> Find the values of the variables<br><br> (Simplify your answers )
SVETLANKA909090 [29]

Answer:

x=88 (alternative angles)

y=31 each

v=41 (alternative angles)

w=20 (alternative angles)

Step-by-step explanation:

for y:

we add all the angles got therefore,

20+41+88+y+20+41+88+y=360(because total angle in a quadilateral is 360°)

298+2y=360

2y=360-298

2y=62

therefore y=62/2=31° for each y

==> 7x =413

==> x = 59

Meaning that Raoul has to read 59 pages on Wednesday

Find the inverse function of f(x)=4x-8
kipiarov [429]

Answer:

f^-1(x)=1/4x+2

Step-by-step explanation:

y=4x-8

change x and y

x=4y=8

switch sides

4y-8=x

add 8

4y=x+8

divide both sides by 4

y=1/4x+2

substitute f^-1(x) for y

f^-1(x)=1/4x+2
