Answer:
y = 50 x = 10.
Step-by-step explanation:
Let's solve for y first.
We know the line angle 80 and angle 2y-5 is on a 180 degree line.
Now we can do our work:
180 - 85 = 95
2y - 5 = 95
95 + 5 = 100
100 ÷ 2 = 50
2(50) - 5 = 95?
The equation is correct, therefore y = 50.
No we do the same thing for the other angles, 90 and 3x + 55.
Again, 180 line.
180 - 95 = 85
3x + 55 = 85
85 - 55 = 30
30 ÷ 3 = 10
3(10) + 55 = 85?
The equation is correct therefore x = 10.
Thus, y = 50 and x = 10.

Answer: Choice B) purple and orange</h3>
The purple graph reflects over the line y = x to get the orange graph. Every point on the purple graph reflects over y = x using the rule (x,y) --> (y,x). So the x and y values swap places more or less.
We do not reflect over any horizontal line, which is why the blue and purple don't pair up as inverse pairs.
---------
The blue doesn't pair with the orange because of two reasons
1) The first local max, or highest hill, on the blue graph means that for some small region/interval, the y value is highest. However, the first bump in the orange graph shows that x is smallest for some y interval. The x and y swap when it comes to inverses.
2) The blue graph has y go off to negative infinity for both endpoints. So x must go off to negative infinity for the inverse (again x and y swap), but this isn't the case. Instead x goes off to positive infinity for both endpoints in the orange graph.

Answer:
68.06 sq. feets
Step-by-step explanation:
Area of room's floor
11.33 × 7 = 79.33
Area of tiled floor
4.83 × 2.33 = 11.278
Area of floor needed to be carpeted
79.33-11.278= 68.06
