Answer:
x= 8/9
Step-by-step explanation:
Open everything up to get 5x+2x-6=-2x+2. Move numbers with an x to the left side and without to the right to have 5x+2x+2x=2+6. Simplify to have 9x=8. Divide by 9 which leaves you with x= 8/9
Answer: 16.5 hours
Step-by-step explanation:
distance=rate*time
132=8*x
Divide by 8 on both sides
x=16.5
Answer:
The answer to your question is: the points are not collinear.
Step-by-step explanation:
Data
AB = 7
BC = 4
AC = 9
Are points A,B and C collinear?
If they are collinear, the distance from AB plus the distance BC must be equal to the distance AC.
Process
dAB + d dBC = d AC
7 + 4 = 9
11 = 9
The distances are different so they are no collinear
Move the x over to the other side
2y=10-5x
Divide both sides by 2 to get the y alone
y=-5/2x+5
Find m from the equation of a line (y=mx+b)
m=-5/2
Slope=-5/2
