By subtracting c on both sides
Answer:
"The rate of Hose A is 1 gallon per minute more than the rate of Hose B"
Step-by-step explanation:
Hose A:
60 gallons every 15 minutes means
60/15 = 4 gallons per minute
Hose B:
y = 3x
y is gallons
x is minutes
we put x = 1 and get:
y = 3*1 = 3
That means 3 gallons per minute
Thus,
the correct choice is C), or third option. 4 is 1 greater than 3 so Hose A is 1 gallons per minute more than the rate of Hose B.
Answer:
C
Step-by-step explanation:
the value of x is 5 sub 5 into the formula your ans will be -14
<span>To do that, you need to set it all to zero and factor:
x^2+8x+15 = 0
(x+5)(x+3) = 0
then put both those in parentheses chunks in their own equations
x + 5 = 0
x + 3 = 0
and then simplify
x = -5
x = -3
So the two points where the parabola crosses the x-axis are -5 and -3.</span>
To find the mean transaction amount. We need to understand mean first.
Mean (or average) is a number that expresses the central value in a set of data, which is calculated by dividing the sum of the values in the set by their number of values.
Here, the transactions shown are
$250, -$60, -$94, $300, and -$186. So there are 5 transactions.
Now mean transaction amount is given by:
So, the mean transaction amount over 5 transactions is $42.00.
