Answer:
Step-by-step explanation:
we would like to find the inverse of the following function:
to do so substitute y for f(x):
interchange variables:
cancel 9 from both sides:
square both sides:
add 4 in both sides:
divide both sides by 4:
substitute back:
and we're done!
Answer:
∠M
Step-by-step explanation:
∠M is the only vertex that does not already have an indicated angle. There are three vertexes, being 90° at ∠K (the box-like figure means it is a right angle, therefore 90°) , 61° at ∠N , and ∠M, which does not have a given angle.
Answer:
1 7/15 or 22/15
Step-by-step explanation:
2/3 = 10/15
4/5 = 12/15

Answer: A) 30</h3>
===========================================
Work Shown:
SM/MK = RM/ML
33/44 = x/40
3/4 = x/40
3*40 = 4*x ... cross multiply
120 = 4x
4x = 120
x = 120/4
x = 30
RM = 30
