F(x) = kx
12 = 8k
k = 12/8 = 3/2
Required equation is f(x) = 3/2 x
X=2
2x-3=-x+3
add three to both sides
add 1x to each side
should be left with 3x=6
divide both sides by 3 to get x alone
your answer then is x=2
8.2*10^-5 can be also written as 0.000082, in standard notation.
Hope this helps.
Your answer would be n=-1/5
24. Since the area of a square is 36, it's best to figure out what the factors of 36 are.
The square root of 36 is going to be 6 so both factors are going to be six.
You don't have to worry about the side lengths being different because it's a square; therefore, the sides can't be uneven like a rectangle characteristically would.
