4 units because u have to subtract 4-0
Answer: The answer for that would be 325
Step-by-step explanation:
If John charge $12 then he has 14 students, and he gets $ 14*12,
If he increases on $2(12+2) , he loses 1 student (14-1), gets (12+2)*(14-1)
if he increases on he loses 2 students (14-2) gets (12+2*2)(14-2)
2+2 (12+2*2)
if he increases 2*3 he loses 3 students, (14-3) gets (12+2*3)(14-3)
2x*3 (12+2*3)
and so on......
if he increases 2*x, he loses x students, (14-x)left, gets (12+2x)(14-x)
(12+2x)
So , his revenue in general =
(12+2x)(14-x)=12*14-12x+28x-2x²=-2x²+16x+168
<em> I think it should look like this
</em>c(x)= -2x²+16x+168
Answer:
<u>y = 3x + 8</u>
Step-by-step explanation:
line a: y = 3x + 11
This means that the slope is 3 and the y intercept is 11.
(-1,5)
line b: y = 3x + b <--- we need to solve for b and plug in the numbers from the coordinates
Just plug in the numbers!
5 = 3(-1) + b
5 = -3 + b
5 + 3 = b
8 = b
The y intercept is b! So the equation is:
y = 3x + 8
The answer is
3(7.25 - 4.5)
3(2.75)
8.25
