Answer: 150 cups
Step-by-step explanation:
Vivian used 25 cups of shampoo every day.
To find out the amount used in 6 days therefore, you should multiply 25 by the number of days which is 6:
= Number of days * Number of cups used per day
= 6 * 25
= 150 cups
Answer:
Let the x = # of pies Larry ate
Jesse ate 2x-5 pies
Total = 16
Your equation is:
x + (2x-5)=16
3x-5=16
3x=21
x = 7
Larry ate 7 pies.
Step-by-step explanation:
Answer:
f(x) = -(1/4)(x - 2)^2 - 1
Step-by-step explanation:
Take any point (x,y) on the graph.
The distance of this point from the focus is equal to the distance of the point from the directrix.
So √ [(x - 2)^2 + (y + 2)^2 ] = y
(x - 2)^2 + (y + 2)^2 = y^2
(x - 2)^2 + y^2 + 4y + 4 = y^2
(x - 2)^2 + 4y + 4 = 0
4y = -(x - 2)^2 - 4
y = -(1/4)(x - 2)^2 - 1 (answer).
