Answer:

A'(6,5),  B'(3,1) and C'(1,6)

Step-by-step explanation:

The reflection of a given point over the line x = 5 doesn't change its y- coordinate.

The distance from the original point to the line must be the same as from the reflected point to the line, then:

distance from A(4,5) to x = 5 is 5-4 = 1, then the x-coordinate of A' is 5+1 = 6

distance from B(7,1) to x = 5 is 7-5 = 2, then the x-coordinate of B' is 5-2 = 3

distance from C(9,6) to x = 5 is 9-5 = 4, then the x-coordinate of C' is 5-4 = 1

Therefore, the reflected points are: A'(6,5),  B'(3,1) and C'(1,6)

50% of 80 solve pls show working<br>pls I know it just try working it​
Eduardwww [97]

Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{40}}}}}

Step-by-step explanation:

\sf{50 \: \% \: of \: 80}

To convert the percent into a fraction , divide it by 190 and remove the % symbol. Then , Simplify the fraction to its lowest term.

⇒\sf{ \frac{50}{100}  \times 80}

⇒\sf{ \frac{1}{2}  \times 80}

Divide 80 by 2

⇒\sf{40}

Hope I helped!

Best regards!!

Determine which of the following sets of ordered pairs represents a function
Illusion [34]

Answer:

B.

Step-by-step explanation:

Every answer besides B. has an input that repeats. A function contains inputs that have exactly one output. This means x values cannot have more than one y value.

Y=1/4x−2y=−2x+3 help solve problem.
8_murik_8 [283]

Answer:

  (x, y) = (2 2/9, -1 4/9)

Step-by-step explanation:

Equate the values of y and solve for x.

  1/4x -2 = -2x +3

  (2 1/4)x = 5 . . . . . . . . add 2+2x to both sides

  x = 20/9 = 2 2/9 . . . multiply by 4/9

  y = -2(2 2/9) +3 = -4 4/9 +3 . . . . substitute for x in the second equation

  y = -1 4/9

The solution is x = 2 2/9, y = -1 4/9.

Find the image of the points after a reflection in the line x=-2​
meriva

Answer:

The Y value part of the point's coordinates will always stay the same, and then calculate the distance from the point's x value to the line -2 and then count the same amount in the opposite direction. For example, if the point was (-3,1), then the point is 1 left from the line, so you will go point one right from the line and get the answer (-1,1)
