Answer:
x=2
Step-by-step explanation:
29/40
10x+391≥503
let x = # of sets
If you need at least 503 knives, both the sets of knives and the initial amount we already have (391) must add to have a number of knives greater than or equal to the minimum required amount.
Walmart: 1.20 divided by 3= 0.4
Sprouts: 1.35 divided by 5= 0.27
Sprouts has a better deal
(0,1)
The mid point of A(-2,2) and B(2,-4) is the coordinates of point P, which is (x,y)
Hence, the line AB = AP + PB.
At point AP: x = (-2+2)/2 = 0
also, point PB: y = (2 - 4)/2 = -1
Therefore, coordinates of point P = (0,-1)
