If the required rate is gallons per minute, then its obvious from the question, that the rate of filling the pool is 10 gallons per minute, and its obviously a constant number.
But for the rate to be in gallons per hour, then
1 minute corresponds to 10 gallons
so
1 hour corresponds to 10x60 = 600 gallons
hence
rate (gallons per hour) = 120,000/600 = 200 gallons per hour.
which is again a constant number.
Answer:
Range = (7,5,-1,-9)
Point 1 = ( -3, 7)
Point 2 = ( -2, 5)
Point 3 = ( 1, -1)
Point 4 = ( 5, -9)
Step-by-step explanation:
g(x)= 1-2x
The domain is x.
The range is y.
g(x) is the function.
To solve this you just input each number from the domain into the function.
g(x) = 1 - 2(-3)
-2 × -3 = positive 6
It is a positive because a negative multipled by a negative equals a positive. This means it is not 1-6 because it is not a negative, it would be 1+6.
1 + 6 = 7
g(x) = 1 -2(-2)
-2 × -2 = positive 4
1 + 4 = 5
g(x)= 1 - 2(1)
-2 × 1 = -2
Since it is multipled 1 time it will be -2. So the equation is still 1-2.
1 - 2 = -1
g(x)= 1 - 2(5)
-2 × 5= -10
A negative multipled by a positive is a negative.
1 - 10 = -9
Now that you have all the numbers put them in parentheses things like the domain
Range = {7,5,-1,-9}
To graph it you need to put in each point by finding the first number of the domain and range and that is your point.
The first point would be (-3,7) and so on and so forth.
Answer:
C
Step-by-step explanation:
.........................
I can not see the trapezoid
I guess you mean that the zeroes are 2 and -3/5.
In factor form the function could be
f(x) = (x - 2)(3x + 5)
expanding we get
f(x) = 3x^2 -x - 10
