Input 15 as the initial value and (3, 90) as x and y to get the equation 90=m(3)+15. Isolate m to get m=25. Each shirt costs $25 and the equation that represents the scenario is y=25x+15.
Answer: Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.
Step-by-step explanation:

Using the form y1 - y2/x1 - x2, we get:
-2 - (-4)/-4 - 3 => -2 + 4/-7 => 2/-7 => -2/7. The slope is the same, therefore the lines are parallel.
Hope this helps.
x = 5 in this problem
do you need a "show work" section too? i can provide that if needed.
(hope this helps!)
Z varies inversely as w ⇒ z*w=k
when z=7 and w=8 ⇒ 7*8=56=k
when w=14 ⇒ z*14=56
⇒z=56/14
⇒ z=4
