-x+xy +4xy-x2
-2x2+5xy
C.-2x2+5xy
Rate of change = 5
Im positive this is the correct answer
According to the given data we have the following equation:
|-ax-b|=c
So, to calculate the value of x we would have to apply the following property:
absolute rule
if |uI=a, a>o, then u=a or u=-a
Therefore, considering the propert above the calculation of would be as follows:
if a<0
-2x-1=-2
-2x=-1
x=1/2
if a>0
-2x-1=2
-2x=3
x=-3/2
The value of x would be 1/2 and -3/2
Step by step
distribute= 4y-12+20y
combine like terms =24y-12
therefore answer is C
