Answer:
x = -5
Step-by-step explanation:
1. Divide both sides by -3
2. Simplify 15/-3 to 5
( 15 divided by -3 is -5)
The functions supplied appear to be the same? Regardless:
We have the equation y = 5x.
Therefore the gradient of this graph will be 5, so for every 1 increase in the y axis, there will be 5 in the x.
It will appear as a straight line passing through the origin and the point (1, 5).
You could say:
y = 4x + 10
John runs 10 miles a week, after every month he adds 4 miles.
y = 3x + 15
Mary runs 15 miles a week, after every month she adds 3 miles.
'y' would represent the total miles and 'x' would represent the number of months.
Step one: Do half of 28. So now you know what one hour is okay.
Step two: You now know three hours is 42 stops
Step Three: total amount in 4 hours 28 times 2 and that is 56 stops
