The answer to this is true
Answer:
4/7 as a decimal is 0.57142857142857.
This is indeed a linear equation. y-4x=9 in standard form is y=4x+9.
7/8% is .875 as a decimal.
Answer:
x=-4, y=2. (-4, 2).
Step-by-step explanation:
5x+6y=-8
-2x+8y=24
-----------------
2(5x+6y)=2(-8)
5(-2x+8y)=5(24)
-----------------------
10x+12y=-16
-10x+40y=120
---------------------
52y=104
y=104/52
y=2
5x+6(2)=-8
5x+12=-8
5x=-8-12
5x=-20
x=-20/5
x=-4
