The answer is:
[B]: -4 .
_____________________________Here is the problem:
_____________________ "Find f(3)."
_______________________ f(x) =

;
______________________________________
Since we are asked to find: " f(3)" ; we consider the number, "3", which is GREATER THAN OR EQUAL TO "-2" ; (that is, " 3

-2" ;
and f(x) = -4 if x

-2 .
_____________________________________________________So, in this case, f(x) = f(3) = -4 ; which is: "Answer choice: [B] ".

Step-by-step explanation:
2x + 1 + x - 13 = 180° because these angles are supplementary
3x - 12 = 180°
3x = 180 + 12
3x = 192 divide both sides by 3
x = 64
2x + 1 ➡ 2 × 64 + 1 = 129°
x - 13 ➡ 64 - 13 = 51°
Answer:
c. 6 cups
Step-by-step explanation:
The proportion is 1 cup of sugar for 1 dozen cookies (1/1). So if you multiply the denominator by 6 you must multiply the numerator by 6, and 6*1=6. Therefore you need 6 cups of sugar to make 6 dozen cookies.
