1/4x. You didn't give us any answer choices, so if that's wrong I apologize but I doubt it is.

F(x)=5(x-2) <br> find x if f(x)=-20

Lapatulllka [165]

Answer:

x = -2

Step-by-step explanation:

f(x)= 5(x-2)

since, f(x)= -20

-20 = 5(x-2)

x-2 = -20/5

x = - 4 + 2

x = -2

Determine a series of transformations that would map polygon ABCDE onto polygon A’B’C’D’E

zalisa [80]

Answer:

Reflected across x-axis followed by a dilation with a scale factor of 2 about the origin.

Step-by-step explanation:

It's clear from the graph,

Polygon ABCDE is reflected across x-axis then dilated so that it overlaps polygon A'B'C'D'E'

Let's choose a point A having coordinates (-2, -1)

By reflecting point A across x-axis,

Rule to be followed for the reflection,

(x, y) → (x, -y)

By this rule, coordinates of the image point A will be,

A(-2, -1) → A"(-2, 1)

Now point A"(-2, 1) has been dilated by a scale factor = k to form an image points A'(-4, 2).

Rule for the dilation of a point about the origin is,

A"(x, y) → A'(kx, ky)

A"(-2, 1) → A'(-2k, k)

Since, coordinates of point A' are (-4, -2),

Therefore, -2k = -4

k = 2

Hence, polygon ABCDE was reflected across x-axis followed by a dilation with a scale factor of 2 about the origin to form polygon A'B'C'D'E'.

I NEED HELP PLEASE !!!Sketch a rectangular prism that has a volume of 36 cubic cm. Label the dimensions of each side on the pris

navik [9.2K]

Answer:

Height: 3cm
Length: 6cm
Width: 2cm

Step-by-step explanation:

To sketch such a Rectangular Prism, all you need to do is to ensure that the product of the dimensions gives 36 cubic cm.

An example is attached:

Height: 3cm
Length: 6cm
Width: 2cm

Volume of a rectangular prism = Length X Height X Width

=6 X 3 X 2

Volume=36 cubic cm
