Report Issue Question text The cost of using light construction equipment is $1,100 for 3 hours or $1,700 for 5 hours. Which of the following functions could represent the cost, C(x), of using the equipment for x hours? Select one: A. C(x)=300x+200 B. C(x)=500x−800 C. C(x)=400x−100 D. C(x)=200x+700

A.

Step-by-step explanation:

This is because you can plug in the two hourly costs into each of the answer choices to check if you are right. Since x stands for x amount of hours, you can plug in the hours you are given into each of the equations and replace C(x) with the cost ($).

A.) C(x)=300x+200

Plugging it in with the first equation, 1100=300(3)+200, that equals to 1100=900+200 and simplified makes 1100=1100.

Plugging in the second equation, 1700=300(5)+200, that equals to 1700=1500+200, making 1700=1700. Making both points fit with the equation. But let's check the other equations.

B.) C(x)=500x-800, using the first point, 1100=500(3)-800. 1100=1500-800, which simplifies to 1100=700. This is not true, thus B cannot be the right answer.

C.) C(x)=400x-100, to save time I'll skip to using the second point. 1700=400(5)-100, turning into 1700=2000-100, which is 1700=1900, and 1900 doesn't equal 1700, so C is wrong as well.

D.) C(x)=200x+700: 1100=200(3)+700, that makes 1100=600+700, which is 1100=1300. This makes D invalid as well.

Checking all the equations, we know that the answer is A.

step-by-step explanation:

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
