Need some help with this math

4 $ on tax and 36 $ on purchase.hope this helps

Step-by-step explanation:

$44

Step-by-step explanation:

Let's set a proportion.

$40 - 100%

$x   - 10%

(40 x 10) : 100= $4.

We found out how much is that 10% BUT Steve payed this amount on top of $40. So, $40+$4= $44.

So select 44

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
