Answer: y = 0.5x
Step-by-step explanation: The total cost of dollars, y is equal to $0.50 per pound x. This is written as y = 0.5x.
Answer:
3.35
Step-by-step explanation:
Take the total cost and subtract off the cost of the tax
We need to determine the tax
71.02 = original cost + original cos* tax rate
71.02 = original cost + original cost* .06
71.02 = original cost (1+ .06)
71.02 = original cost (1.06)
Divide each side by 1.06
71.06/1.06 = original cost before tax
67 = original cost before tax
Now to find the cost of each light bulb
Divide by the number of light bulbs
67/20=3.35
Answer:
Let x = time in minutes
Let y = water in ounces
<u>Part A</u>
If the water drips at a constant rate of 2 ounces per 5 minutes, then
x = 0, y = 0
x = 10, y = 4
x = 20, y = 8
<u>Part B</u>
Graph is attached.
Please note that the scales on the y and x axes are <em>different</em>.
<u>Part C</u>
Answer:
There is only one solution. x = 2
Step-by-step explanation:
3(x + 2) = 14 - x
3x + 6 = 14 - x
3x + x = 14 - 6
4x = 8
x = 2
Yes this is proportional. The constant term is the y is 2 times then the x . Y= x•2
