What coordinate pair satisfies both 5x - 3y=22 and -4x + y=-19

hello : coordinate pair is:  (5 ; 1)

Step-by-step explanation:

you have this system :

5x - 3y=22 (1)

-4x + y= -19(2)

by (2) : y = 4x -19

put y in (1) : 5x - 3 (4x -19) =22

5x -12x +57 = 22

- 7x = -35

x = 5

but : y = 4x -19  so : y = 4(5) -19   = 1

coordinate pair is:  (5 ; 1)

725 parts per hour.

step-by-step explanation:

hi there, this answer is actually really simple.

you can set it up as 1450/2 or 3625/5 to find the answer.

they want to know how much per hour is being made, so you just divide.

1450/2=725.

and that's how many are produced per hour.

hope this . : )
