Answer:

A'(-6,4)\\B'(-3,-5)\\ C'(1,1)

Step-by-step explanation:

The given vertices are

A(-6,-4)\\B(-3,5)\\C(1,-1)

Now, when we reflect a figure across the x-axis, the coordinates of that figure change. In this case, all vertical coordinates (y-variable) must change to its opposite in order to ensure the reflection across the x-axis.

A(-6,-4) \implies A'(-6,4)\\B(-3,5) \implies B'(-3,-5)\\C(1,-1) \implies C'(1,1)

Therefore, the vertices of the reflected image are

A'(-6,4)\\B'(-3,-5)\\ C'(1,1)

The height of a cylinder is equal to the diameter of the base What expression represents the volume of the cylinder, in cubic un
Sveta_85 [38]

Answer: 3 units

Step-by-step explanation:

the volume of a cone C = πr²h/3

C = 18π, h =2x, r = diameter/2 = 2x/2 =x

18π = π* x²* 2x/3

divide through by π

18 = x² * 2x/3

multiply through by 3

54 = 2x³

divide through by 2

27 = x³

x =∛27 = 3

x = 3 units = radius

Is the figure a rectangle? Explain.
luda_lava [24]

The correct option is b. No, it is not a rectangle because the sides of the parallelogram do not meet at right angles.

<h3>How to explain the information?</h3>

The figure is a parallelogram and one diagonal measure 28 units.

In this case, it is not a rectangle because the sides of the parallelogram do not meet at right angles.

Therefore, the correct option is B.

Please Help. Lateena solved the equation below. Is her solution correct? Explain why or why not?
bonufazy [111]

Answer:

Not correct

Step-by-step explanation:

Given:

x² - 6x - 7 = 0

The following equation can be solved correctly by factoring Thus,

x² - x + 7x - 7 = 0

x(x - 1) +7(x - 1) = 0

(x - 1)(x + 7) = 0

(x - 1) = 0

x - 1 = 0

x - 1 + 1 = 0 + 1

x = 1

Or

(x + 7) = 0

x + 7 = 0

x + 7 - 7 = 0 - 7

x = -7

Therefore, the solution would be x = 1 or x = -7

Lateena solution is therefore NOT CORRECT because she used a wrong method.
