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

Answer:
26
Step-by-step explanation:
Firstly, plot the points on graph paper which you can find on the internet. The first number in the ordered pair, (the ones in parenthesis), is the x coordinate. The other number is the y coordinate. Put these onto a graph which is attached. The perimeter is 26.
Answer:
39.25 cubic feet of paint will be needed by Ellis.
Step-by-step explanation:
Volume of a cylinder:
The volume of a cylinder of radius r and height h is given by:
How much paint will Ellis need to paint all the surfaces of the 10 fenceposts?
This is the combined volume of these 10 fenceposts.
They are each 5 feet tall and have a diameter of 1 foot.
Radius is half the diameter, so . Also
10 fenceposts:
Each has the same volume, so:
39.25 cubic feet of paint will be needed by Ellis.
