Exponents are used when we find the area of a shape, used in banking for finding compounding interest, and used to describe very large and very small numbers. (They are used for many other things, of course, but I don't think you want that kind of list)
You can use exponents to write numbers by writing the exponent for the number of times you are multiplying the base.
Step-by-step explanation:
2A
x=1 y=3
x=4 y=0
y=mx+b
3=m+b
0=4m+b
3=-3m
m= -1
0=-4+b
b=4
y= -x +4
2B
x=2 y=0
x=0 y= -4
0=2m+b
-4=b
b=-4
0=2m-4
2m=4
m=2
y=2x-4
X^2 + 6^2 = {sqrt (117)}^2
x^2 + 36 = 117
Solve for x.
x^2 = 81
x = 9
