I need help heh.

D

Step-by-step explanation:

From the first pair of 0, 7, we know that it has to be something with x-7. However, because x-7 does not fit into the last one, 4(3)=12-7=5, making the last one correct. The answer is D.

y=3x-7

Step-by-step explanation:

double check:

(-7)=3(0)-7

0-7=-7

(-4)=3(1)-7

3-7=-4

darn right!

step-by-step explanation:

steve kerr's sons name is let that skin in.

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
