1 hr 35 minutes um i just subtracted
hello :
the quadratic function is :
<span> f(x) = a(x-1)(x+1)
but ; f(0) = -6</span>
a(0-1)(0+1) = -6
-a = -6
a=6
<span>the equation is : 6(x-1)(x+1) = 0</span>
a) Simply do 0.135(13.5%)*550 to get that his rent increases by $74.25.
b) Simply do 550+74.25 to get that his new rent is $624.25.
c) 624.25/550 = 1.135, or 100%+13.5%, the amount his rent increased.
<em>Hope it helps <3</em>
If the variables disappear and you get a statement that is never true,such as 0=5 or 4=7 then there is no solution meaning when graphed the two equations will form parallel lines which never interact
In mathematics, 'is' would be the equal sign. And 'of' would be the multiplcation sign. The missing number would be any variable.
56 is 28% of a number would be translated algebraically to:

Solving for x, we get:

Divide 28 on both sides

Multiply 100 on both sides
56 is 28% of 200
