Answer:

Step-by-step explanation:
The given function is
f(x) = 4x
As we know
f(x) = y, which implies x= 
Therefore,
y = 4x
x = 
as x= 
So,

replacing y by x in the above expression

So our inverse function is 
Answer:
x = 7.5
Step-by-step explanation:
A scale factor of 0.75 means all the dimensions are multiplied by 0.75. When the dimension 10 is multiplied by 0.75, it becomes ...
... x = 0.75 × 10 = 7.5
Using complementary angles, <X is equal to <Z, so it's <Z = 35°.
A) Yes. we don't have enough information so this can not be determined.
B) No, it would just be an outlier.
Answer: -2
(-5)(-1)x=(10)(-1)
5x = -10
x = -2
