Answer:


Step-by-step explanation:

Think of of this as a function in which the number of pounds is a function of the number of hours. Each piece of given information is a point. Each point has the format (x, y) = (hours, pounds), where hours is x and is the independent variable, and pounds is y and is the dependent variable.

You have two points (4.5, 1445) and (7, 2320). First find the slope of the line that passes through those two points. Use the slope formula,

m = (y2 - y1)/(x2 - x1).

Then using the slope and the point-slope equation of a line, find the equation of the line. The point-slope equation of a line is

y - y1 = m(x - x1),

where m = slope, and the point is (x1, y1).

Try it. If you have questions or need extra help, just comment.

How many square feet of outdoor carpet will we need for this hole?
pogonyaev
Given:
Level 1 : Length = 5 ft ; Width = 2 ft
Level 2 : Length = 6 ft ; Width = 2 ft
Level 3 : Length = 4 ft ; Width = 2 ft

Area = L x W

Level 1 = 5 ft * 2 ft = 10 ft²
Level 2 = 6 ft * 2 ft = 12 ft²
Level 3 = 4 ft * 2 ft = <u>  8 ft²</u>
Total Area                30 ft²

Outdoor carpet should measure 30 square feet to cover the hole.

Alekssandra [29.7K]
Answer: option d. C (0,3), D (0,5).

Justification:

1) The x - coordinates of the vertices A and B are shown in the diagrama, They are both - 4, so the new vertices C and D must be in a line parallel to y = - 4.

2) The y-coordinates of the  vertices A and B are also shown in the diagrama. They  are equal to 3 and 5 respectively.

3) We can see that the new points C and D must be over a parallel line to y = - 4 and that their distance to the points A and B has to be the same distance of the point R and S to U and T.

That distance is 4, so the line may be y = - 7 or y = 0.

4) If the line is y = 7 the points C and D would have coordinates (-7,3) and (-7,5), but this points are not among the options.

5) If the line is y = 0 the points C and D would have coordinates (0, 3) and (0,5), which is precisely the points of the option d. That is the answer.
