21 and -4, because -4x21 = -84, and 21+-4 (– 4) = 17
Answer:
See below.
Step-by-step explanation:
No, a reasonable estimate is around 7 * 6 = 42.
Round $6.99 to $7 and multiply by the 6 family members.
1. y=4 x=0
2. I think no solution
The error was the Jacob multiplied 2.5 by 3 instead of dividing. Instead it should be.
5 beads are used for every 3 inches, that makes 5/3 beads per inch.
Thus that can be modeled by the graph y=x*5/3 where x is the number of inches and y is the number of beads.
