Answer:
y = 55 + 8x
255 gallons
Step-by-step explanation:
Let x be the number of minutes the tank is being filled with water.
A water tank
- Already contains 55 gallons of water;
- Water flows into the tank at a rate of 8 gallons per minute;
- In x minutes, 8x gallons flow into the tank.
Hence, the tank will contain 55 + 8x gallons of water.
If y gallons is the volume of water in the tank after x minutes, then
y = 55 + 8x
When x = 25, then
Answer:
Step-by-step explanation:
Suppose numbers are <em>x</em> and <em>y</em>
<u>Product of </u><em><u>x</u></em><u> and </u><em><u>y</u></em><u> is </u><em><u>-2</u></em>
<u />
And sum of <em>x</em> and <em>y</em> is <em>-1</em>
