Answer: option c
Step-by-step explanation:
Find the x-intercept and y-intercept of each line.
To find the x-intercept, substitute 
into the equation and solve for "x".
To find the y-intercept, substitute 
into the equation and solve for "y".
- For the first equation:
x-intercept
y-intercept
Graph a line that passes through the points (7.25, 0) and (0, 9.66)
- For the second equation:
x-intercept
y-intercept
Graph a line that passes through the points (0.5, 0) and (0, -0.33)
Observe the graph attached. You can see that point of intersection of the lines is (5,3); then this is the solution of the system. Therefore:

Answer:
School buses range anywhere from 20 to 45 feet in length ok?
Answer:
It would take 50 minutes
Step-by-step explanation:
<u>Distance, velocity and time</u>
The speed is the rate at which the distance changes with respect to time. If x is the distance, t is the time, the speed v can be obtained by
We know the trip takes 40 minutes when traveling at 50 miles/hour. The distance can be determined by isolating x in the above equation
The given time is expressed in minutes, we need to convert it to hours. 40 minutes is 
. The distance is
If the speed was 40 miles/hour, the same distance would be covered in t hours, taken from the above equation as
Answer: OPTION B
Step-by-step explanation:
Let be "x" the acceptable lengths for the rod.
You know that the ideal length of the metal rod is 30.5 centimeters and the measured length may vary from the ideal length by at most 0.015 centimeters.
Therefore, knowing this, you can say that the acceptable lengths must be:
Therefore, the range of acceptable lengths for the rod is the following:
This range matches with the one shown in the option B.
