Substitute the value of a = -2 to the expression -3(6a + 4):
-3(6 · (-2) + 4) = -3 · (-12 + 4) = -3 · (-8) = 24

Answer:
C) -5/12
Step-by-step explanation:
To find the slope of a line with given points, you divide the difference of y-coordinates by the difference of the x-coordinates of those same 2 points.
x's:-9-3=-12
y's:-1-(-6)=5
Then, you put the answer of the y's in the numerator, and x's in the denominator, giving you 5/-12, but you can't have a negative in the denominator, moving it up to become -5/12 as the slope.
The points have the same x-coordinate, so they lie on a horizontal line. The distance between them is the difference between their y-coordinates.
2.5 - 1.4 = 1.1
The distance between the two points is 1.1
Percent means “out of 100.” So 5% really means 5/100.
11 / 15% = 11 / (15/100) = 1100 / 15 = 220 / 3. That’s the answer.
