C(x) = 300.
Our question becomes simple: 300 = x^2-40x+610
x^2-40x+610-300 = 0
x^2-40x+310 = 0
Now find the value for x with either the quadratic formula or by factorization.
Let me know how it goes. Giving the full answer won’t help you improve
The other endpoint is (10, -8
Since the figures are similar, we can establish a rule of three as follows.
We know that the area of the smaller figure is

, and its volume is

. We also know that the area of the larger figure is

; since we don't now its volume, lets represent it with

:



We can conclude that the volume of the larger figure is

; therefore, the correct answer is
a.
Y=-4x+10

Answer:
x > 
Step-by-step explanation:

Add 3 and 1 to get 4.

Use the distributive property to multiply 5 by 9−x.

Subtract 45/5 from both sides.

Since 44/4 and 45/4 have the same denominator, subtract them by subtracting their numerators.

Multiply both sides by -4/5, the reciprocal of -5/4. Since -5/4 is negative, the inequality direction is changed.

Multiply -1/4 times -4/5 by multiplying numerator times numerator and denominator times denominator.
