Answer:

21 J

Step-by-step explanation:

Work = Force * Distance

We know the force to be 7 Newtons.

We know the distance to be 3 meters.

multiply 7* 3

Answer: 21 J (Joules) of work done.

Step-by-step explanation:

W = Fs, where F is force and s is displacement.

F = 7 N

s = 3 m

W = 7 N * 3 m = 21 N*m, or 21 J

Jelly ate 3 apples. This represents 50% of the bag of apples. How many apples were originally in the bag
rjkz [21]
<h3>Answer:  6 apples</h3>

x = number of apples originally

50% of x = 0.50*x = amount of apples eaten = 3

0.50x = 3

x = 3/0.50 ....... divide both sides by 0.50

x = 6

You can think of 50% as 1/2. If 3 apples represent half the bag, then the full bag is 6 apples. So half of 6 is 3.

Which is the slope of the graph of the equation below? X - y = 5
icang [17]

First, make it into slope intercept form. Subtract x form both sides

x (-x) - y = 5 (-x)

-y = -x + 5

Isolate the y. Divide -1 from both sides

(-y)/-1 = (-x + 5)/-1

y = x - 5

The slope in the form: y = mx + b, is m, which is next to the x

In this case, the m is 1

You're slope is 1

hope this helps

You can find the rise by _ the Y-coordinate of the left point from the y-coordinate of the right point
bixtya [17]

Answer:

Subtracting

Step-by-step explanation:

We know that the slope of a line is given by the rise over run. where rise is vertical difference between two points and run is the horizontal distance between the points.

\text{if }(x_1,y_1) \text{ and }(x_2,y_2)\text{ are two points on a line, then the}\\\text{slope of the line is given by}\\\\\text{Slope, }m=\frac{y_2-y_1}{x_2-x_1}\\\\\text{since slope}=\frac{\text{Rise}}{\text{Run}}, \text{ so Rise}=y_2-y_1\\\\\text{so we can find the rise by subtracting the Y-coordinate of the left point }\\\text{from the y-coordinate of the right point}.
