Answer: 1,500 liters or 396.2581 gallons
Step-by-step explanation: To figure out how much water flows every minute, you‘ll have to multiply 25 liters to 60, which is how many seconds are in a minute. Once, you multiply 25 to 60, you should get a final result of 1,500 or 1,500 liters.
*Reminder*: <u>You can convert 1,500 liters to gallons if you want, but only if your teacher allows you to.</u>

Answer:
the domain and range are all real numbers
Step-by-step explanation:
Answer:y = -4.5x - 22
Step-by-step explanation:
The standard form of finding the equation of a line is expressed as y = mx+c
m is the slope
c is the y intercept
Get the slope:
m = y2-y1/x2-x1
Given the coordinates (-6,5) and (-4,-4)
m = -4-5/-4+6
m = -9/2
m = -4.5
Get the y-intercept
Substitute (-4,-4) and m = -4.5 into y = mx+c
-4 = -4.5(-4) + c
-4 = 18 + c
c = -4-18
c = -22
Get the required equation:
Recall that: y = mx+c
y = -4.5x - 22
Hence the required equation is y = -4.5x - 22
Step-by-step explanation:
Answer:
(x + 5)(x + 2) / (x³ - 9x)
Step-by-step explanation:
We need to find a common denominator.
factor each denominator
x² - 3x = x(x - 3)
x³ - 9x = x(x² - 9) = x(x + 3)(x - 3)
x² - 9 = (x + 3)(x - 3)
As the factors of the first and third denominators are subsets of the second, the second is the LCD. This immediately eliminates the last two options as possible solutions.
Now we multiply each term by the missing factor over itself (1)
<u>(2x + 5)(x + 3)</u> - <u>(3x + 5)</u> - <u>(x + 1)(x)</u>]
(x² - 3x)<u>(</u>x + 3<u>)</u> (x³ - 9x) (x² - 9)(x)
[(2x² + 11x + 15) - (3x + 5) - (x² + x)] / (x³ - 9x)
[2x² + 11x + 15 - 3x - 5 - x² - x] / (x³ - 9x)
(x² + 7x + 10) / (x³ - 9x)
(x + 5)(x + 2) / (x³ - 9x)
