4.08, or 4 2/25 :) hope this helps
Y = -1/2x + 4
x + 2y = -8
x + 2(-1/2x+4) = -8
x + -x + 8 = -8
8 = -8
There correct answer is "no solution"
Answer:
2
y = -0.5x + 10.5
Step-by-step explanation:
put a negative sign and 1 on top of the number next to the x to get the line thats perpendicular
2
y = -0.5x + 10.5
The ones with ✓ signs are irrational the rest are rational. note this is not generally true but it is for this particular set
Answer:
81%
Step-by-step explanation:
First, let's set up 3 equations:
w*0.6 = x
x*1.5=y
y*0.9=z
Now, we can substitute x in the second equation for w*0.6:
w*0.6*1.5 = y
Lastly, we can substitute y in the last equation for w*0.6*1.5:
w*0.6*1.5*0.9=z
w*0.81=z
Therefore, z is 81 percent of w.
