Answer:3x-4y
Step-by-step explanation:
To express the sum of (2x-5y) and (x+y),
We are going to have
2x-5y+x+y
The next thing to do is to collect the like terms;
Then we have;
2x+x-5y+y
Answer realized will now be
3x-4y
I don't have a graph, but I can try to show you how to do it.
Go to -3 on the y-axis (the vertical one in the middle)
Put a dot there. That's your y-intercept.
From the dot go up 1 line, then go right 2 lines.
Put a dot where you end up. Continue doing so until you get enough for your graph.
Answer:
<h2><u>
24 inches</u></h2><h2><u>

Step-by-step explanation:
c = πd
75 = 3.14d
Divide both sides by 3.14
23.89 = d
Rounded
24 inches
The tub holds 43 gallons.....it contains 18.....(43 - 18) = 25....so it needs 25 gallons.....after 5 minutes, the tub is full.....so it fills at a rate of 25/5 = 5 gallons per minute
y = 5x + 18....where y is the total gallons and x is the number of minutes
but we need it in standard form....
y = 5x + 18
-5x + y = 18
5x - y = -18 <== standard form
