Answer:
Assume x is directly proportional to y :
when y is 9, x is 2:
substitute to find value of k :
Therefore, equation is:
Answer:
13 Boxes with $41 left over
Step-by-step explanation:
$600/$43 = 13.9 (so she can buy 13 boxes of light fixtures)
$43 x 13 = $559
$600-$559=$41 left over
Answer:
60 miles per hour
Step-by-step explanation:
First, put the equation in a fraction.
You would put 180 up top because people always say miles per hour not the other way around.
You can see the dividing line as your "per" and your "hour" would be the bottom number.
To find the unit rate, you will divide the numerator (180) and the denominator (3).
Your final answer should be 60 miles per hour.
Answer:
A
Step-by-step explanation:
A graph that represents a proportional relationship usually has the line cutting through the line of origin (0, 0).
The graph in option A does not have the line passing through the point of origin (0, 0), therefore, it does not represent a proportional relationship.
For an equation that represents a proportional relationship, it is written in the form of y = kx
Where, k is the constant of proportionality.
Therefore, the two equations given represents a proportional relationship.
