Answer:
7) 1
8) -2
9) undefined (no slope)
10) 4/3
11) -2/7
12) 0
Step-by-step explanation:
to find the slope when given to points ... minus the y values and x values
formula :
y - y
------ = slope
x - x
Together it would take a total of 4 hours to completely fill the pool.
1760 divided by 4 equals 440. This is the amount of liters that the second pump will fill the pool in 4 hours, so 440 divided by four is the amount that the second pump will fill the pool in one hour. 440/4= 110.
Now we add 110 to 330 to get the hourly rate of both pumps filling the pool. 110+330=440.
1760/440 equals 4.
So it takes 4 hours for both pumps to fill the pool.
Hope this helps!
(3w + 9) + (6w + 7) + (8w - 4) =
= 3w + 9 + 6w + 7 + 8w - 4 =
= 3w + 6w + 8w + 9 + 7 - 4 = <u>1</u><u>7</u><u>w</u><u> </u><u>+</u><u> </u><u>1</u><u>2</u>
The equation 7x + 3x - 18 = 6(x+3) is 9
<h3>What is equation?</h3>
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
given:
7x + 3x - 18 = 6(x+3)
7x + 3x - 18 = 6x+18 [Distributive Property]
10x-18= 6x+18 [Addition Property of Equality]
10x-6x= 18+18 [Combine Like Terms ]
4x=36 [Subtraction Property of Equality]
4*x=36 [Multiplication Property of Equality]
x=36/4 [Division Property of Equality]
x=9
