4. Yes, line L is parallel to M because they do not intersect, the angles do not matter.
5.
A. 2 and 3 would be Alt. Int. Angles.
B. 2 and 4 are congruent angles.
$1248.93, you just have to multiple 850 by 1.08, then that number by it, until you've multiplied by 1.08 5 times
Answer:
40m
Step-by-step explanation:
0.2/1=8/x
cross multiply
8*1=0.2x
8=0.2x
8/0.2=x
x=40
Answer:
D infitently Many
Step-by-step explanation:
A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line). This article reviews all three cases. One solution. A system of linear equations has one solution when the graphs intersect at a point.
Answer:
14 and 6
Step-by-step explanation:
Let's start by naming the first number x.
We can name the second number y.
We can set up equations to model our situation.
x+y=2x-8
x-y=2y-4
Let's simplify the equations.
x+y=2x-8
Subtract 2x from both sides
-x+y=-8
__________
x-y=2y-4
Subtract 2y from both sides.
x-3y=-4
Add the two equations together to eliminate x.
x-3y=-4
-x+y=-8
________
0x-2y=-12
-2y=-12
Divide both sides by -2.
y=6
The second number is 6.
Plug that back in.
x+6=2x-8
Subtract x from both sides
6=x-8
Add 8 to both sides
x=14
The first number is 14
