Answer:
18/5
Step-by-step explanation:
Supplementary angles add up to 180º
If one is 40º, then the other is (180º-40º) = 140º
None of those choices describes a plane.
choice C is the only example of a plane.
Answer:
False
Step-by-step explanation:
4g + 7 = 5g - 1 - g
Simplify:
4g + 7 = 4g - 1
Subtract both sides by 4g:
7 = -1
There are no solutions to this equation.
Answer:
y=-1/5x+1
Step-by-step explanation:
divide both sides by 5: 1/5x+y=1
subtract 1/5x so y is alone since slope-intercept has y=mx+b: y=-1/5x+1
