Answer:

1) Expression

2) Equation

3) Equation

4) Expression

Step-by-step explanation:

An equation always contains an equal sign, so in this case, if it doesn't contain an equal sign, it's an expression.

For 2 and 3, you can see that there is an equal sign, but for 1 and 4, there is not.

Therefore, 1 and 4 are expressions and 2 and 3 are equations.

I hope this helped.

The bases of an isosceles trapezoid are represented by 4x and 2x.. The height of the trapezoid is represented by (x − 6). Which
Igoryamba
The area of a trapezoid is calculated by the equation,
                          A = 0.5(b₁ + b₂)h
where b₁ and b₂ are the bases and h is the height. When we substitute the given expression for the dimensions in the given,
                          A = 0.5(4x + 2x)(x - 6)
                          A = 0.5(6x)(x - 6) = 3x² - 18
Thus, the answer is letter A.

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

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'.

Given the following linear function sketch the graph of the function and find the domain and range. f( x ) = 2/7 x− 2
Savatey [412]

Answer:

Domain: All Real Numbers Range: All Real Numbers

Step-by-step explanation:

The domain and range is going to be infinite. The linear function will be using the x and y- axis in order to continue being a function. The y-intercept will be -2 on the y-axis. I recommend using the rise-over-run method for your slope value. from the point (0, -2) on the y-axis. Go up two on the y-axis, and right 7 on the x-axis.

Sorry, it may be difficult to explain through words.
