Answer:
36 cups of water
Step-by-step explanation:
Make a proportion, where x is the number of cups of water needed:
=
Cross multiply and solve for x:
2x = 72
x = 36
So, 36 cups of water will be needed
I got 69.4444444444
To figure out this problem you need to do 72%/100% multiplied by 50/n. Then you cross multiply. (100x50 and 72xn) You get 5,000 and 72n. 72n can be divided by 72. Then you just do 5,000 divided by 72 and you get 69.4444444444

Answer:
Vertex:
Y-intercept:
Step-by-step explanation:
The x-coordinate of the vertex would be and the y-coordinate of the vertex is whatever the output is given the value of x.
Therefore, the x-coordinate of the vertex is
This means the y-coordinate of the vertex is
So, the vertex is
The y-intercept of a function is the y-value at which x=0, or the y-value when the function crosses the y-axis. Therefore, if we plug x=0 into the function, we see that , so our y-intercept is -8 or (0,-8).
I attached a graph below to help you visualize the vertex and y-intercept given the function.
