Answer:

The correct option is A

A) -10 ≤ x ≤ 10 , -10 ≤ y ≤ 10

Step-by-step explanation:

We have been given a system of equation:

y = -13x + 17

y = 5x - 23

We have to determine the best window range from the following options:

A) -10 ≤ x ≤ 10 , -10 ≤ y ≤ 10

B) -20 ≤ x ≤ 0 , -20 ≤ y ≤ 0

C)  0 ≤ x ≤ 20, 0 ≤ y ≤ 20

D) 20 ≤ x ≤ 40 , 20 ≤ y ≤ 40

The graph of both the equation is attached below, we can see that the graph shows the solution at the point (2.222, -11.869), where x is positive and y is negative

Now consider the options

Option A includes the solution

Option B doesn't show positive values for x

Option C doesn't show negative values for y

Option D doesn't include the x or y part of the solution

Second option is the right choice.

Step-by-step explanation:

Volume=2\pi rh+2\pi r^2\\\\V=2\left(3.14\right)\left(13\right)\left(14\right)+2\left(3.14\right)\left(13\right)^2\\\\\approx2205\:in^2
