Answer:
y = 50
Step-by-step explanation:
All triangle angles add up to 180 degrees.
To set this equation up, you need to add everything given in the triangle and set it equal to 180:
y + y + 80 = 180
<em><u>Add like terms:</u></em>
2y + 80 = 180
<u><em>Subtract 80 from both sides:</em></u>
2y + 80 = 180
- 80 - 80
___________
2y = 100
<u><em>Divide both sides by 2:</em></u>
y = 50
<u><em>If you're unsure, you can plug in the 50 for y:</em></u>
y + y + 80 = 180
50 + 50 + 80 = 180
100 + 80 = 180
180 = 180
Answer:
It's definitely not parallel... I think it's neither...
Step-by-step explanation:
Tip: if it is parallel, the slope is the same. The formula for finding slope is y two minus y one divided by x two minus x one.
Answer:
option c
->(x,-y)
Step-by-step explanation:
When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed), So we can see from the graph that,
point M(-5,4) is reflected to m'(-5,-4)
similarly,
point N(-2,3) is reflected to N'(-2,-3)
point L(-4,2) is reflected to L'(-4,-2)

Step-by-step explanation:
Reason is, adult tickets and child tickets are two different things, so they require two different variables, and two different equations because they have two different sums. (This was probably already obvious to you though).
Hope this helps :)
I tried my best to explain.
