Table shows ordered pair that satisfys the function y=3x/2

x: 0,   1,  2,    3,  4,    5

y: 0, 1.5, 3, 4.5, 6, 7.5

Step-by-step explanation:

To create a table that satisfies a function, you need to first choose some x values. Some common x values are 0, 1, 2, 3, 4, 5 or -2. -1, 0, 1, 2, but it doesn't matter which numbers you choose.

Then, plug the x values in to the function to get a table of y-values.

I chose the x-values as 0, 1, 2, 3, 4, 5 but these numbers could be anything. To find the y, I plugged each x into the function.

y = 3 * ( 0 ) / 2 = 0 / 2 = 0

y = 3 * ( 1 ) / 2 = 3 / 2 = 1.5

y = 3 * ( 2 ) / 2 = 6 / 2 = 3

y = 3 * ( 3 ) / 2 = 9 / 2 = 4.5

y = 3 * ( 4 ) / 2 = 12 / 2 = 6

y = 3 * ( 5 ) / 2 = 15 / 2 = 7.5

in the opening of the question the word 'service' is associated only with the pretax value.

the closing part of the question asks: how much did she pay for the

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
