Answer:
No
Step-by-step explanation:
For a proportional relationship :
y = kx
Where , k = constant of proportionality
Taking the first set of data:
x = 50 ; y = 10
10 = 50k
k = 10/ 50 = 1/5
Hence, the proportional equation or relation is :
y = 1/5x
Check if this is true for other data points on the data :
Taking the second data point :
x = 85 ; check if y will be 20
From :
y = 1/5x
y = 1/5*85
y = 85/5
y = 17
Since ;
y value from the equation isn't the same as that in the table, then the table does not show a proportional relationship.

Answer:
$40.12.
Step-by-step explanation:
We have been given that your family went to a pancake house for breakfast and spent $34 your family decides to leave at 18% tip how much is the tip. We are asked to find the total amount of bill with the tip.
The total amount of bill with the tip will be cost of breakfast plus 18% of cost of breakfast.
Therefore, the total amount of the bill will the tip would be $40.12.
The solution is: (6,0)
Step-by-step explanation:
Given equations are:
<u>Part A:</u>
The graph is made using the online tool Desmos.
The graph is attached as a picture
<u>Part B: Solution from graph:</u>
On the graph we can see that both lines intersect at (6,0)
So the solution is x=6 and y=0
<u>Part C: Algebraic Verification</u>
Putting y= 1/3x-2 in equation 1
Adding 12 on both sides
Dividing both sides by 3
Putting x = 6 in equation 2
Hence,
The solution is: (6,0)
