Answer:

A

Step-by-step explanation:

4x - 5x + 2 = 3(2x - 4)

-x + 2 = 6x - 12

+x          +x

2 = 7x - 12

+12       +12

14 = 7x

/7     /7

Answer:

<h3>A. 2</h3>

Step-by-step explanation:

To find the value of x, first, you have to isolate it on one side of the equation. Isolate x on one side of the equation.

4x-5x+2=3(2x-4)

4x-5x=-x (Combine like terms and group like terms.)

-x+2=3(2x-4)

3(2x-4) (Expand.)

<em><u>DISTRIBUTIVE PROPERTY:</u></em>

A(B+C)=AB+AC

A(B-C)=AB-AC

3*2x=6x

3*4=12

6x-12

-x+2=6x-12

-x+2-2=6x-12-2 (Subtract 2 from both sides.)

12-2 (Solve.)

12+2=14

-x=6x-14

-x-6x=6x-14-6x (Subtract 6x from both sides.)

-x-6x (Solve.)

-x-6x=-7x

-7x=-14

-7x/-7=-14/-7 (Then, divide by -7 from both sides.)

-14/-7 (Solve.)

-14/-7=2

x=2

Hence, the correct answer is (A.) 2.

There is a line that includes the point (6,–10) and has a slope of –9. What is its equation in point-slope form?
8_murik_8 [283]

Answer:

A slope of zero means a horizontal line (parallel to the x axis). So the line is y=-6, which is the y intercept. There is no x term because y=-6 for all x.

Triangle XYZ, with vertices X(-2, 0), Y(-2, -1), and Z(-5, -2), undergoes a transformation to form triangle X′Y′Z′, with vertice
Debora [2.8K]
<h2>Answer with explanation:</h2>

1)

The vertices of X,Y and Z are:

X(-2, 0), Y(-2, -1), and Z(-5, -2)

Now, when X,Y and Z are translated by using the translation transformation:

         (x,y) → (x+6,y-2)

Then we obtain the transformation:    

X(-2, 0) → X′(4, -2)

Y(-2, -1) → Y′(4, -3)

Z(-5, -2) →  Z′(1, -4)

The type of transformation that triangle XYZ undergoes is a translation transformation by the rule:   (x,y) → (x+6,y-2)

2)

Next when we reflect the triangle X'Y'Z' across the x-axis then we obtain X"Y"Z"

Since, the rule that follow on reflecting across x-axis is:

           (x,y) → (x,-y)

Hence, we get:

X′(4, -2) → X″(4, 2)

Y′(4, -3) →  Y″(4, 3)

Z′(1, -4) → Z″(1, 4)

Hence, the type of transformation that triangle X′Y′Z′ undergoes is a reflection transformation (on reflecting across x-axis)
