Answer: I think the reflection would be (-7,-2)

Step-by-step explanation:

The rule of a reflection over the x-axis is that the x remains the same but the Y becomes it’s opposite (the sign is changed)

Answer:

(-7,-2)

Step-by-step explanation:

Graphed on the Cartesian plane.

                     |

  +                 |

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

  O                |

                     |

+ represents original

o represents reflected.

Both points are at x = -7. When reflected across the x-axis, the point is seems to have moved lower than from its original position.

What is the solution for: 10n^2+n^2+16
ivanzaharov [21]

The solution is n= <u>+</u> 4i/√11

Step-by-step explanation:

step 1: 10n^2+n^2+16=0

step 2: 11n^2+16=0

step 3: 11n^2= -16

step 4: n^2= -16/11

step 5: taking square root on both sides,

            n= √(-16)/√11 (square root of a negative number is a <u>complex term</u> 'i')

            n= <u>+</u> 4i/√11

Phoenix [80]

First, classify each line segments of triangle that are the same in both triangles.

RS = XU

RT = XW

ST = WU

Second, divide to find the scale ratio.

7.5/3 = 2.5

16/6.4 = 2.5

15/6 = 2.5

Since the scale ratios are identical, the triangles are similar.

Therefore, the answer is [ Yes, the sides are in the ratio 2:5 ]

Best of Luck!
