Choices:
_____________________________________________________
[B]: "complementary angles, 180° " ; and:
_____________________________________________________
[C]: "supplementary angles, 90° " ;
_____________________________________________________
can automatically be ruled out ; since by definition:
</span>→ Complementary angles always add up to 90° — NOT 180° ;
and: supplementary angles always add up to 180° — NOT 90° .
<span>_____________________________________________________
Note: "Adjacent angles" refer to "supplementary angles" ; which, by definition add up to 180</span>° . Futhermore, looking at the image provided,
we see that ∠1 and ∠2 are, in fact "adjacent" and that ∠1 and ∠2 comprise the entire portion of a "straight line" (being intersected by a transversal)" ;
and as such; ∠1 and ∠2 are supplementary angles—
and as such—add up to 180° .
(which rules out: Choice [A]: "complementary <span>angles, 90°) ;
</span>→ <span>and demonstrates the correct answer:

-4 as if it was -1/4 that would mean it goes to right 4 times and down 1
Answer: The answer would be f^-1 (x) = x/2 - 3/2
The value of x would be 5 for the model 2x+4.
Rearrange unknown terms to the left side of the equation,

Combine like terms
By calculating the sum or difference : -x = -5
Lets divide both sides of the equation by the resulting coefficient 5
So x = 5
