Answer:
42.9
Step-by-step explanation:
20% of 50 is 10
so its 40
40 + taxes
40 + (40*.0725)
Ie 32^2 - 4ac=0 so ac=256 and a+c=130
So, that means:2 equations ac=256 a+c=130 ie c=130-a
So,a(130-a)=256 so 130a -a^2=256 ie a^2-130a +256=0 (a-2)(a-128)=0
Finally,giving a= 2 or a=128 so, a=2 c=128 or a=128 c=2
Since, a>c , a=128 and c=2 ie (128,2)
That would be choice C the limit of f(x) is 2.
You can eliminate graphs A and C because the lines are dotted and you can eliminate graph B because the shaded part is below the solid line and the equation is telling you to shade above so the answer is D
