9x + 18 /4 + -5x + 24 / 4
The correct answer for this question is this one: 5 / 7
<span>There exists the same question from other source that has the continuation of the problem. <em>Use proportions to test your measurements and see if they match this ratio. Height is 5ft</em>
So this how to solve this:
Set the equation as:
7x = 5
x = 5 / 7</span>
<span>f(x<0)=-f(x>0)=-x^2+5x+12
When x>0, x^2-5x-12=12, x=8, y=12
Therefore, f(x)=12 goes through point (8,12).</span>
The answer is 21
252 / 12 = 21
I hope this helped :)
