Answer: The system forms the same line.
Step-by-step explanation:
3x - y = -2
-y = -3x - 2 (subtract 3x from both sides)
y = 3x + 2 (divide both sides by -1)
First equation: y = 3x +2
Second equation: y = 3x +2
THEY ARE THE SAME LINE —> there are infinitely many solutions.

Answer: m = 25</h3>
====================================================
Work Shown:
Triangle ABC is congruent to triangle DEF. The order of the lettering is important because it tells us how the angles pair up. We see that angle B and angle E are the second letters of ABC and DEF respectively. Because the triangles are congruent, this leads to angle B = angle E.
Angle B is shown to be 20 degrees, so,
angle E = angle B
2(m-15) = 20
m-15 = 20/2
m-15 = 10
m = 10+15
m = 25
------------------
A slightly alternative way to solve:
2(m-15) = 20
2m-30 = 20
2m = 20+30
2m = 50
m = 50/2
m = 25
------------------
Checking the answer:
2(m-15) = 20
2(25-15) = 20
2(10) = 20
20 = 20
We get the same thing on both sides, so we end up with a true equation. This means the first equation is true when m = 25. The solution has been confirmed.
Answer:
.8
Step-by-step explanation:
funtions: a, b, c...
formulas: 1, 2, 3...
A and 5, F and 2, B and 4, D and 1, C and 3, E and 6
$140 divided by 4 is $35 which is a fifth of the original price so u multiply that 5 to get 5 fifths which is $175
The original is $175
