Answer:
replace x with -4
f(-4)= 4(-4) + 2
4(-4) + 2 = -16 + 2 = -14
(2/6) × 24 = m
(1/3) × 24 × 3(to take out (1/3)) = m × 3
24 = m×3
24÷3 = m×3 ÷3
8 = m
m = 8
So the answer should be B. 8

Answer:
Step-by-step explanation:
Create equations:
10X+15y=2575.
X+Y=210.
Solve for X: X=210-Y, and sub it into the other equation: 10(210-Y)+15Y=2575. Solve for Y: 2,100-10y+15y=2575, 5y=475, y=95.
Sub Y into the original problem: X+95=210. Solve: X=115.
