Answer:

x=5/2

Step-by-step explanation:

4x-2=2x+3

1) Add 2 to both sides:

4x=2x+5

2) Subtract 2x from both sides:

2x=5

3) Divide both sides by 2:

x=5/2

  • m = (-2 - 6)/(3 - 7) = -8 / -4 = 2
  • m = 2
<h3>Q2</h3>

Angles 2 and 6 are on the corresponding sides of the parallel lines, hence are corresponding angle

<u>Correct option is </u>

  • A. Corresponding
<h3>Q3</h3>

Congruent triangles have congruent corresponding parts

PLEASE HELP PLEASE!!!
Alja [10]

Answer:

F; A translation of 6 up and 4 left and a reflection across the x-axis

Step-by-step explanation:

Here, we want to perform the translation that would move S to S’

to do this, we can have a subtraction

For 1 to move to -3 on the x-axis;

it means there is a leftward shift of upto 4 units

For -8 to turn to 2;

this is positive; there is a vertical upward translation of upto 10 units on the y-axis

This option is not directly available; thus we have to factor the reflection

if we reflect on the x-axis, the y-axis value becomes negated; if we reflect on the y-axis, the x-value becomes negated

The correct answer is thus;

A translation of 6 up and 4 left, followed by a reflection across the x-axis
