Answer:
42
Step-by-step explanation:
For the proportion ...
Form the "cross products" by multiplying both sides of the equation by 7x (the product of the denominators. This gives you ...
After you have formed the "cross products", divide by the coefficient of x:
x = 84/2 = 42
The value of x is 42.

Answer:
You are right
Step-by-step explanation:
So basically find the absolute maximum of the graph that the function creates, the highest peak is the spot with the greatest y-value, in this case is (60, 1600).
The x-value that creates the greatest y is also the x-value of the vertex for that function of yours (since your function has end behavior of both ends down). To find the x-value of the vertex, get the average of the 2 x-intercepts. So (20+100)/2, which is 60.
For this problem, the answer is choice A.
