Segment FG begins at point F(-2, 4) and ends at point G(-2, -3). The segment is translated 3 units left and 2 units up, then ref
Alexus [3.1K]

Answer:

F'G' = 7

Step-by-step explanation:

Given

F = (-2,4)

G = (-2,-3)

Required

Distance of F'G'

The transformation that give rise to F'G' from FG are:

  • Translation
  • Reflection

The above transformations are referred to as rigid transformation, and as such the side lengths remain unchanged.

i.e.

F'G' = FG

Calculating FG, we have:

FG = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}

Where:

F = (-2,4) --- (x_1,y_1)

G = (-2,-3) --- (x_2,y_2)

FG = \sqrt{(-2 - -2)^2 + (4 - -3)^2}

FG = \sqrt{(0)^2 + (7)^2}

FG = \sqrt{0 + 49}

FG = \sqrt{49}

Take positive square root

FG = 7

Recall that:

F'G' = FG

F'G' = 7

Solve. State the number of solutions.
Oksi-84 [34.3K]

Answer:

a. x=8

b.Step 1: Simplify both sides of the equation.

2(2x−2)=4x−4

(2)(2x)+(2)(−2)=4x+−4(Distribute)

4x+−4=4x+−4

4x−4=4x−4

Step 2: Subtract 4x from both sides.

4x−4−4x=4x−4−4x

−4=−4

Step 3: Add 4 to both sides.

−4+4=−4+4

0=0

Answer:

All real numbers are solutions.

c. Step 1: Simplify both sides of the equation.

3(x+1)=4x+7−x

(3)(x)+(3)(1)=4x+7+−x(Distribute)

3x+3=4x+7+−x

3x+3=(4x+−x)+(7)(Combine Like Terms)

3x+3=3x+7

3x+3=3x+7

Step 2: Subtract 3x from both sides.

3x+3−3x=3x+7−3x

3=7

Step 3: Subtract 3 from both sides.

3−3=7−3

0=4
