The results would give a higher average than it should. Reason being is that football players on average are heavier than others due to the demand of the sport.

Match the correct y=mx+b equation to the graph: <br><br> pls show work/explanation!
Basile [38]

Answer:

y=-3x+2

\boxed{m=-3,\ b=2}

Step-by-step explanation:

<u>Equation of a line</u>

To define the equation of a line, we only need two points through which it passes. The graph shows two clear points to choose: (0,2) and (1,-1)

Set up the equation of the line by using the formula

\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)

\displaystyle y-2=\frac{-1-2}{1-0}(x-0)

Operating

y-2=-3x

Rearranging

y=-3x+2

\boxed{m=-3,\ b=2}

What could you do to the equation 100x + 300 = 500 to change it into x + 3 = 5?
VashaNatasha [74]

Answer:

2+3=5

Step-by-step explanation:

100x + 300 = 500

100x = 500 - 300

100× = 200

100x/100 = 200/100

therefore ^x = 2

x + 3 = 5

2 + 3 = 5

It takes 20 minutes to drive to a mall at 30 mph. How long in minutes will it take to drive to the mall at 40 mph?
makvit [3.9K]

At a speed of 40 mph, it would take 15 minutes to drive to the mall

The first step to take in order to determine the answer is to determine the distance driven to the mall. This information is not given so it has to determined.

Distance = speed x total time  

  • speed = 30 mph.
  • time = 20 minutes

Speed is measured in hours, while time is measured in minutes. Both data has to be converted to the same time measurement

To convert time to hour, divide by 60 = 20 / 60 = 1/3

Distance = 1/3 x 30 = 10 m

The second step is to use the distance determined in the previous step to determine the time it would take to travel at a speed of 40 mph

Time = Distance / Average Speed

10 / 40 = 1/4 hours

To convert hours to minutes, multiply by 60 :1/4  x 60 = 15 minutes

In order to determine the time that it would take to drive to the mall, first determine the distance to the mall. Use the distance and speed to determine the time
