Answer:
If a = 3
a -7 = -4
Step-by-step explanation:
Here, we want to find the value of a -7 given that a = 3
To find this value, we are going to make a substitution
We simply substitute 3 for the value of a
we have this as;
3 -7 = -4
so you're going to need to find the slope. in order to do that use (y2-y1)/(x2-x1)
(7-(-2))/(0-8)
simplify
9/-8
simplify -9/8
now using y=mx+b, we need to find b. so we can plug in the coordinates of (0,7) or (8,-2). let's use (8,-2) because it involves more math.
y=mx+b
-2=(-9/8)(8)+b
multiply (-9/8) by 8 to get -9
-2=-9+b
add 9 to both sides
7=b
so our equation is now
y=-(9/8)x+7

*plz give me brainliest if right*
Green paper > 18 / 3 = 6 inch pieces
Red paper > 24 / 6 = 4 pieces of paper
total = 4 + 3 = 7 piece of paper in total :)
