slope = m\implies
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{4-1}{1-1}\implies \cfrac{3}{0}\impliedby und efined

A water delivery truck is filling the water tank at Morgan's house. The truck arrived with 2400 L of water. The number of liters
Luda [366]

Answer:

11.81 minutes

Step-by-step explanation:

Here is a simple step-by-step explaination of how to solve this word problem:

Since the truck has 2,400L in it to begin with, the first part of our equation will be 2,400L

L = 2400L&#10;&#10;

Next we know that the water in the truck decreases at a <u>rate</u> of 110L/min, or <u>Liters per minute</u>.

So we will put that in the equation:

L = -110L + 2400L

Now that we have our equation set up, its time to solve.

To figure out how much water it needs to lose in <u>total</u> to end up with 1100 L left, we subtract 1,100 from 2,400.

2,400 - 1,100= 1,300&#10;&#10;

Now we can take that number and divide it by how many liters per minute were lost.

1,300/110=11.81

So the total amount of time it took for the truck to have 1,100 L left is 11.81 minutes. Your answer would be

B. L=-110t + 2400, t=11.8 min

Hope this helps! : )

Mars2501 [29]

Answer:

2. -x^{2} +3x+15

3. -x^{2} -x+9

Step-by-step explanation:

We add like terms together to simplify

2.  3x²-4x²= -x²     -2x+5x= 3x  6+9= 15  all equal to -x²+3x+15

3.  2x²-3x²= -x²      6x-7x= -x    8+1=9      all equal to -x²-x+9

Answer:

Hope it helps!

Step-by-step explanation:

Sub y=5x into y=2x+3

so

5x=2x+3

3x=3

x=1

plug x=1 into y=5x

y=5

Checking work

Plug (1,5) into y=2x+3

5=2(1)+3

5=5

Plug (1,5) into y=5x

5=5(1)

5=5
