all the answers are correct idc if you dont belive me if you want the answers for other math assignments either say thank you or get this post to 10 likes i need it to fuel my bbig ego
a. Every sweater knitted is $56 dollars earned. To calculate this, divide the money earned (y) by the number of sweaters knitted (x). For example, for the first entry (7 sweaters knitted and $392 earned), divide $392 by 7 to get $56.
b. Dollars/1 sweater is called a unit rate. In this case, the unit rate is $56/1 sweater.
c. This relationship is linear because there is a constant rate of change between the number of sweaters knitted and the money earned. Additionally, if 0 sweaters are knitted, there are $0 earned, indicating a consistent pattern.
To answer these questions, we need to examine the relationship between the number of sweaters knitted (x) and the money earned (y).
a. Every sweater knitted is the same amount of dollars earned. To determine this amount, we can find the ratio of dollars earned to the number of sweaters knitted for any given data point. Let's choose the data point (7 sweaters knitted, $392 earned):
Dollars earned per sweater = Total dollars earned / Number of sweaters knitted
Dollars earned per sweater = $392 / 7
Dollars earned per sweater ≈ $56
Therefore, every sweater knitted is approximately $56 earned.
b. Dollars/1 sweater is called a unit rate or rate. In this case, the rate would be $56 per sweater.
c. This relationship is linear because there is a constant rate of change between the number of sweaters knitted and the dollars earned. To verify this, we can look at the points on the graph.
If 0 sweaters are knitted, the dollars earned would be 0 as well. This means that 0 sweaters result in 0 dollars earned.
