Answer:
y=3*x
Step-by-step explanation:
john bought 3 notebooks for 9 dollars
so 9/3=3
notebooks costed 3 dollars each
x-number of notebooks
y-cost of notebooks
so
y=3*x
because 3 dollar cost every notebook you could buy.
if i buy 2 notebooks
so x=2
y=3*2=6 dollars
if I buy 3 notebooks
then y=3*3=9 dollars
end this way continues
Since all points are equidistant from the origin, they could be radii, so this could be a circle
<u>Answer:</u>
Distance = 3r
<u>Step-by-step explanation:</u>
We are to write an algebraic expression and then simplify it for the given situation:
<em>The distance traveled by a train in three hours with a constant speed of r miles per hour.</em>
We know the formula of distance linking the speed and the time.
Distance = speed × time
Substituting the given values to get:
Distance = r × 3
Distance = 3r
