Hurry To much points!

a) 0, 4, 8, 12, 16

explanation- simply add 4 to the previous number. 0+4= 4, 4+4= 8, 8+4= 12, etc etc.

b) 0, 8, 16, 24, 32

explanation- the same as letter a.

c) if you multiply the top number (the x value) by two, then you will get the bottom number (the y value)

explanation- 0+0= 0, 4+4= 8, 8+8= 16, 12+12= 24, and 16+16= 32

d) (0,0), (4,8), (8,16), (12,24), and (16,32)

explanation- the first number comes from the set in letter a (the x value) and the second number comes from the set in letter b (the y value).

e) -

explanation- find a spare piece of graph paper and put the points down. for example, (4,8) would be four places to the right on the horizontal line (the x-axis), and then down 8 places, still staying in the four postion. so four over, eight down. the vertical line is called the y-axis.

Hope this will help somewhat :)

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

the answer is y = 11.54

hope this : )
