Here are the answers i’m order from top to bottom 12x/5 , 12x+5, 12x-5
Answer: y = 4x - 12
Step-by-step explanation:
Answer:
x+120 , if x < -120
x+12 , if x > -12
x+12 , if x < -12
x+12 , if x = -12
x÷3 , if x > 0
x÷3 , if x < 0
Step-by-step explanation:
Well whatever is in the absolute value sign is always positive.
8x +7y = 39 multiply everything by 2
2(8x +7y = 39)
16x +14y = 78
+4x - 14y= -68
-------------------------
20x = 10
20x /20 = 10/20
x = 1/2
Plug x into first formula
8 x + 7y =39
8(1/2) 7y=39
4+ 7y =39
4-4+7y =39-4
7y =35
7y/7 = 35/7
y = 5
(1/2, 5)
