Mathematics
1 answer:
zloy xaker [14]4 years ago
4 0

Answer:

  (x, y) = (1, 1)

Step-by-step explanation:

Using the second equation to substitute for y in the first equation, we have ...

  x = -2x +3

  3x = 3 . . . . . . . add 2x

  x = 1 . . . . . . . . .divide by 3

  y = x = 1

The solution is (x, y) = (1, 1).

_____

If you have the graph, you can read the solution from it as the coordinates of the point where the lines cross.

Which statement accurately explains whether a reflection over the X-axis and a 180° rotation would map figure ACB onto itself?​
Arlecino [84]

Using transformation rules, it is found that the correct option is:

No, A'C'B' is located at A(-1,1), C'(-3,4) and B'(-5,1).

--------------------

  • The transformation rule for a reflection over the x-axis is (x,y) \rightarrow (x,- y)
  • The transformation rule for a rotation of 180º is (x,y) \rightarrow (-x,-y)

  • After the reflection over the x-axis: (x,y) \rightarrow (x, -y)
  • Taking the reflection, and rotating: (x,-y) \rightarrow (-x, -(-y)) = (-x,y).
  • Not the same rule, that is, (x,y) \rightarrow (x,y), so it would not map figure onto itself.
  • A(1,1) would be mapped to A(-1,1), for example, thus, the correct option is:

No, A'C'B' is located at A(-1,1), C'(-3,4) and B'(-5,1).

The team won 18 of its 30 games. What was the team’s won-lost ratio?
NemiM [27]

Answer:

18:12 (accurate)

3:2 (simplified)

Step-by-step explanation:

The team won 18 games out of 30 total games. Find the amount of games lost by simply subtracting 18 with 30:

30 - 18 = 12

The ratio you are trying to find is won to lost, or won:lost. Plug in the corresponding numbers to the corresponding terms:

won:lost ⇒ 18:12

18:12 is the ratio.

If the teacher asks you to simplify, factor both sides. Divide 6 from both sides:

(18)/6 : (12)/6

3:2

3:2 is your simplified ratio.
