Answer:
40
Step-by-step explanation:
Add all the sides together which is 40
One side is 9.
second side (3x+1) is 28.
third side (4x-9) is 27.
f(x)=4x
To find the inverse, first change f(x) to y:
y = 4x
Now switch the variables:
x = 4y
Solve for Y:
Divide both sides by 4:
y = x/4
Now replace y with the inverse function f^-1(x):
f^-1(x) = x/4
Answer:
XY = 10 cm
Step-by-step explanation:
XY is a midsegment and is half the length of the 3rd side DE, that is
XY =
DE =
× 20 = 10 cm
