Equation 1) y=2x
Equation 2) y=x + 1
Rearrange the equations so that x and y are on the same side.
1) -2x+y=0
2) -x+y=1
Subtract equations with each other.
Now you have: -x=-1
x=1
Plug in x.
y=2(1)
y=2
(1,2)

(X+2)^2-4 = (X+2)(x+2)-4
Factor:
X^2+4x+4-4
X^2+4x
X(x+4)
X=0, x=-4
Answer:
18.18%
Step-by-step explanation:
-Percent error is defined as the deviation as a percentage of the actual value.
#Given the actual sold units is 110 and the predicted is 90, the percent error can be calculated as:
Hence, the perecent error is 18.18%
