Answer:
$19.50
Step-by-step explanation:
First, we find the number of gallons in 100 cups.
1 gallon = 16 cups
100 cups * (1 gallon)/(16 cups) = 6.25 gallons
100 cups is the same as 6.25 gallons.
Now we multiply the number of gallons by the cost per gallon.
6.25 gallons * 3.12 $/gallon = $19.50
X+y=8
2x^2-y=-5
elimination method means you link the 2 equations together to make one
these two already have y in the perfect form where you can cancel it out +y and -y so no need to perform any other action to a certain equation.. all you need to do is add them now
2x^2+x=3
Answer
The line of symmetry x = -4
Step by step explanation
Here we have to use the formula.
The symmetry of a parabola x = -b/2a
Now compare the given equation y = 3x^2 + 24x -1 with the general form y = ax^2 + bx + c and identify the value of "a" and "b"
Here a = 3 and b = 24. Now plug in these values in to the formula to find the line of symmetry.
x = -24/ 2(3)
x = -24/6
x = -4
Therefore, the line of symmetry x = -4.
Thank you.
