Answer:
250%
Step-by-step explanation:
Where: 80 is the old value and 280 is the new value.
Percent change = [(New - Old ) / |Old|] x 100%
Percent change = [(280 - 80) / |80|] x 100 = [(200) / 80] x 100 = 250 % (decrease)
In this case we have a positive change (increase) of 250 percent because the new value is smaller than the old value.
Answer:
x=2 x=-4
Step-by-step explanation:
x^2 +2x-8=0
Factor
What numbers multiply to -8 and add to 2
-2*4 = -8
-2+4 =2
(x-2) (x+4) =0
Using the zero product property
x-2 =0 x+4 =0
x-2+2=0+2 x+4-4=0-4
x=2 x=-4
