Answer:it’s going to be b
Step-by-step explanation:
Answer:
|x-3|+4 = 12
|x-3| = 12-4
|x-3| = 8
now solve for both positive and negative values
x - 3 = 8 | x - 3 = -8
x = 8 + 3 | x = - 8 + 3
x = 11 | x = -5
solution set : { 11, -5 }
Step-by-step explanation:
Answer:
y=6
Step-by-step explanation:
y=3x x=2
y=3(2)
y=6
<span>A) 2x - 7y = 13
B) 3x + y = 8
Multiplying equation B by 7
B) 21x + 7y = 56 then adding it to A
</span><span>A) 2x - 7y = 13
23x = 69
x = 3
y = -1
</span>
Y = 7.5*200 +500
y = 1500 +500
y = 2000
2000 gallons are in the pool 200 minutes after the pump is turned on.
