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

HELP!!!!
OverLord2011 [107]

Answer:

Step-by-step explanation:

You just need the distance formula here.  It's very simple to follow:

d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

which, for us, looks like this:

d=\sqrt{(13-4)^2+(19-7)^2} and

d=\sqrt{9^2+12^2} and

d=\sqrt{81+144} and

d=\sqrt{225} so

d = 15
