Given point B is located at
ELEN [110]

Answer: \Large\boxed{Point~B'~=~(-4,~-2)}

Step-by-step explanation:

<u>Given information</u>

Point B = (-2, -4)

Reflection line: y = x

<u>Concept:</u>

When reflecting over the line y = x, the position of y and x in the original coordinate switches places.

This is because it is " y = x ", assuming that they could interchange

<u>Find the coordinate of Point B'</u>

Original (x, y) = (-2, -4)

Point B' = (x', y') = (y, x) = \Large\boxed{(-4,~-2)}

<em>Please refer to the attachment below for a graphical understanding</em>

Hope this helps!! :)

4x + 10 = 2x - 14<br> Find the value of x.
Gre4nikov [31]

Answer:

x= -12

Step-by-step explanation:

Simplifying

4x + 10 = 2x + -14

Reorder the terms:

10 + 4x = 2x + -14

Reorder the terms:

10 + 4x = -14 + 2x

Solving

10 + 4x = -14 + 2x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2x' to each side of the equation.

10 + 4x + -2x = -14 + 2x + -2x

Combine like terms: 4x + -2x = 2x

10 + 2x = -14 + 2x + -2x

Combine like terms: 2x + -2x = 0

10 + 2x = -14 + 0

10 + 2x = -14

Add '-10' to each side of the equation.

10 + -10 + 2x = -14 + -10

Combine like terms: 10 + -10 = 0

0 + 2x = -14 + -10

2x = -14 + -10

Combine like terms: -14 + -10 = -24

2x = -24

Divide each side by '2'.

x = -12

Simplifying

x = -12
