Identify the domain and range of each relationship. Represent the relation with a mapping diagram. Is the relation a function?
Ivenika [448]
Remember, to be a function, all elements in the domain should correspond to one element in the range. 
The domain is the x coordinate, range is the y coordinate.
The domain we can solve for as the set {4.2, 5, 7}. The range is the set {0, 1.5, 2.2, 4.8}.
But we see that an element in the domain corresponds to more than one element in the range, thus making it not a function.

I have the equations 8x + 3y = 20.50 and 4x + 5y = 22.50<br> How do I solve for x and y?
snow_tiger [21]
8x + 3y = 20.50
-
4x+5y=22.50
=
4x-2y=-2, so you have to divide each number by 2, then
2x-y=-1, so

-y=-1-2x /-1, y=1+2x, then replace it with one original equation like the first one for instance:
8x+3(1+2x)=20.50, then
8x+3+6x=20.50, then
14x=20.50-3
14x=17.5
x=1.25, then solve y:\
y=1+2*(1.25)
y=1+2.5
y=3.5,
So answer is x=1.25, and y=3.5

How do I find, x and y?
AleksAgata [21]

Answer:

  • x = 52°
  • y = 128°

Step-by-step explanation:

The triangle is isosceles, so the angles on either end of the parallel bases are congruent. Right away, that tells you y = 128°.

The angles at the side of a trapezoid are supplementary, so ...

  x = 180° - 128°

  x = 52°
