Answer:
f(3) = -13
Step-by-step explanation:
To answer this question, we plug 3 into the place of x, so the equation now looks like;
f(3) = -5(3) + 2
We simply apply PEMDAS by multiplying -5 and 3, then adding 2 to get;
f(3) = -13
Hope this helps!

Answer:
6
Step-by-step explanation:
3. y + 1 = 4(x - 2)
4. y = 4x + 11
6. 8x - 2y = 6
Subtract the 5x to get
3y=-5x+7
Then divide the whole equation by 3 to finally get
Y=-5/3x+ 7/3
$30
You can get this by setting up the equation below.
75 =
Then you would cross multiply to see what the base cost is. Then you could divide that number by the new number, 5000, to get the new cost.
