Answer:

13\frac{7}{16} laps can Fred run in one hour.

Step-by-step explanation:

Given Statement: Fred is running on the school track. He can run 10\frac{3}{4}  laps in \frac{4}{5}  of an hour.

Unit rate are expressed as a quantity of 1, such as 3 feet per second or 7 miles per hour, they are called unit rates

From the given condition we have;

In \frac{4}{5} he can run \frac{43}{4} laps

Unit rate per hour = \frac{\frac{43}{4} }{\frac{4}{5} }

                              =\frac{43}{4} \times \frac{5}{4} = \frac{215}{16} laps

Therefore, Fred can run in one hour is, 13\frac{7}{16} laps.

Tell whether x and y show direct variation. x + y = 6​
Over [174]
<h3>Answer: Not direct variation</h3>

The reason why is because it can't be written in the form y = kx

If we solved the given equation for y, we get y = -x+6. It has a y intercept of 6, but it should be zero if we wanted a direct variation equation.

I need a little help here please
erma4kov [3.2K]

Answer:

Plot points at (0,1) and (-3,3) and draw a line going through both points.

Step-by-step explanation:

Let's start by graphing the y intercept.

y=mx+b

m is the slope. b is the y intercept. Since the equation is y=-2/3x+1, we can conclude the y intercept is 1. We graph a point at (0,1).

If you didn't know the y intercept is where the line intercepts the y-axis.

Now, from the point (0,1) we go up 2 and to the left 3 as it is a negative slope. We reach (-3,3). Plot a point there. Then draw a line going through both points. There's your line!
