Ah, direct variation/proportion.
That is simply a linear equation with a y-intercept of 0.
So... let's solve this.
Simply put, a direct variation multiplies the x-value by a constant to get the y-value.
Let's take the point
on this graph and solve for the constant of proportionality:
We easily solve that and get our answer of
. (B)
Answer:
9cups of dried split peas
8 qts of water
3 cups of chopped onion
4 cups chopped celery
8 lbs Ham shank
Step-by-step explanation:
The recipe serves 8 people, so to figure out how much you need to serve 32 people you multiply each measurment by 4 because 8 x 4=32.
2 1/4 x 4 = 9
2 x 4 = 8
3/4 x 4 = 3
1 x 4 = 4
2 x 4 = 8
Okay to split a segment in half you just need to find the midpoint of the two endpoints. Mathematically this is just the average of the coordinates of the endpoints which is:
mp=((x1+x2)/2, (y1+y2)/2)
Which in this case is:
mp=((-2+3)/2, (4+7)/2)
mp=(1/2, 11/2)
mp=(0.5, 5.5)
So the x-coordinate by itself is just 0.5, or answer c.
Answer:
10.50x = 63
You'll divide 63 by 10.50 to get 6 weeks.
