Answer:
0.5 meters (50 cm.)
Explanation: 2 divided by 4=0.5=50 cm.
Step-by-step explanation:
9(-2) =-2(-2)+3(-2)-5
9(2)=-2(4)-6-5
9(0)=-2(4)-6-5
0=-8-11
0=-19
Answer:
x=-15/2, y=1/8. (-15/2, 1/8).
Step-by-step explanation:
3x+4y=-22
x-4y=-8
------------------
4x=-30
x=-30/4
simplify
x=-15/2
-15/2-4y=-8
4y=-15/2-(-8)
4y=-15/2+8
4y=-15/2+16/2
4y=1/2
y=(1/2)/4
y=(1/2)(1/4)
y=1/8
If xy=0, assume that x and/or y=0
so we already gots factored
therfor
assume
3n-2=0 and 4n+1=0
solve
3n-2=0
3n=2
n=2/3
4n+1=0
4n=-1
n=-1/4
n=2/3 and/or -1/4
