I think that the answer that is highlighted in blue is correct. I am not sure for this one. But, “both the table and graph are proportional” seems correct.
Answer: The equation would be W = 500 + 30T
Step-by-step explanation: The variables given are, W which represents the amount of water, and T which represents the time in minutes that water has been added. Already there is 500 liters in the water tank to start with, that means as you begin to add water, its simply an addition to the already existing 500 liters, (that is + 500).
Also you are told that you can add water at a rate of 30 liters per minute, that is you have one T for every 30 (or simply put 30T).
Therefore the equation that correctly relates W to T is shown as;
W = 30T + 500
With this, your table of values would now be shown as;
x = 1, y =530
x= 2, y = 560
x = 3, y = 590
x = 4, y = 620
x = 5, y= 650
Then your graph is as shown in the image attached.
Answer:
Step-by-step explanation:
By the way, please use the symbol " ^ " to indicate exponentiation:
f(x) = x^2
Shifted 1 unit to the right, we get g(x) = (x - 1)^2
Vertically stretched by a factor of 5, we get h(x) = 5(x - 1)^2
Reflected over the x-axis: j(x) = -5(x - 1)^2
