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

Graph (-3, 2) (5, 2) (5, -3) and (-3, -3) and find the perimeter.
Nostrana [21]

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.

Ellis is painting wooden fenceposts before putting them in his yard. They are each 5 feet tall and have a diameter of 1 foot. Th
Naya [18.7K]

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:

V = \pi r^2h = 3.14r^2h

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 r = \frac{1}{2} = 0.5. Also h = 5

10 fenceposts:

Each has the same volume, so:

V = 10(3.14)r^2h = 31.4(0.5)^2(5) = 39.25

39.25 cubic feet of paint will be needed by Ellis.

I’m not sure how to slove this problem it’s a equilateral triangle and I’m trying to find out what the side is equal to.
Lerok [7]

Answer:

AB = 5/4 y - 1  = 5/4 (12/13) -1 = 2/13

AC= 7/3 y - 2 = 7/3 (12/13) -2 = 2/13

Step-by-step explanation:

Because it is a equilateral triangle, it means all sides have the same length.

AB = AC

5/4 y - 1 = 7/3 y - 2

5/4 y - 7/3 y = -2 +1

-13/12 y = -1

y = 12/13

input y to the equation.

AB = 5/4 y - 1  = 5/4 (12/13) -1 = 2/13

AC= 7/3 y - 2 = 7/3 (12/13) -2 = 2/13

Hope it helps you.
