1. y = 4x + 9 ; m = 4 ; b = 9
the slope is 4 because there’s a pattern of +4 going down the function table in the “y” column
and b= 9 because at the number 0 on the x line has 9 in the y box
2. y = 3x - 1 ; m = 3 ; b = -1
basically the same thing as the first one just different numbers
Answer:
$19.20
Step-by-step explanation:
8.00x140%=$11.20
8.00+ 11.20 = 19.20
y = k/x, where k is the variation constant.
We need to find k.
5 = k/15...This equation leads to the correct value of k (our variation constant).
5(15) = (k/15)(15)
75 = k
Done!
So start by putting the negative sign into the second polynomial.
-(6x^2-2x-9)
-6x^2+2x+9
then combine like terms with the first polynomial
5x^3+4x^2-6x^2-2x+9
and you will get
5x^3-2x^2+2x+9
Hope this helps you.
