First: work out the difference (increase) between the two numbers you are comparing. Increase = New number - Original Number
Then: divide the increase by the original number and multiply the answer by 100. % Increase = Increase ÷ Original Numberｘ100<span>
30 - 22 = 8
8</span> ÷ 22ｘ100 = 36.3636363636
X^2 + 10x + 11 = 0
x^2 + 10x = -11
x^2 + 10x + 25 = -11 + 25
(x + 5)^2 = 14 <===
x + 5 = (+-) sqrt 14
x = -5 (+-) 3.74
x = -5 + 3.74 = -1.26 <== solution
x = -5 - 3.74 = - 8.74 <== solution
Y= -x + 2 and y= 3x - 4
As these both equal y, you know that they both equal each other so
-x + 2 = 3x - 4
