Answer:
12 slots
Step-by-step explanation:
1/3 of an hour = 20 minutes
4 hours * 60 =240mins/20mins=12
Your ratio is 6:5
This means that it is 6/5.
You have to find a common number to either divide or multiply that can work for both the numerator and denominator.
6/5 doesn't have any common number to divide without getting a remainder
But we can multiply by a common number such as 2
6×2 = 12
5×2 = 10
= 12/10. ☆= the ratio is 12 : 10
or even by 3, =the ratio 18:15
So since the vertex falls onto the axis of symmetry, we can just solve for that to get the x-coordinate of both equations. The equation for the axis of symmetry is , with b = x coefficient and a = x^2 coefficient. Our equations can be solved as such:
y = 2x^2 − 4x + 12:
y = 4x^2 + 8x + 3:
In short, the vertex x-coordinate's of y = 2x^2 − 4x + 12 is 1 while the vertex's x-coordinate of y = 4x^2 + 8x + 3 is -1.
Answer:
49/4
Step-by-step explanation:
x^2+7x=4
Take the coefficient of x
7
Divide by 2
7/2
Then square it
(7/2) ^2 = 49/4
Add this to both sides of the equation to complete the square
