A
Step-by-step explanation:
beacause if you try to multiple 4x7.5 divided by 2 try it
B is the answer, every other answer can be simplified
Answer:
B
Step-by-step explanation:
So we have the function:

To find the inverse, flip f(x) and x, change f(x) to f⁻¹(x), and solve for it. Thus:

Subtract 32 from both sides:

Multiply both sides by 5/9. The right side will cancel. Thus:

Our answer is B.
And we're done!

Answer:
x=41
y=139
Step-by-step explanation:
x+y = 180 since they form a straight line
y is 3x +16
y = 3x +16
Replace y in the first equation
x+3x +16 = 180
Combine like terms
4x +16 = 180
Subtract 16 from each side
4x+16-16 =180-16
4x =164
Divide each side by 4
4x/4 =164/4
x = 41
y = 3x +16
y = 3*41 +16 = 123+16 =139
