Try a few:

1+3+5=9 too small
5+7+9= 21 just right

The greatest integer is 9

Will Mark Brainliest to the smartest and best answer!!!!! What is the measure of each interior angle in a regular 24-gon? If nec

Reika [66]

Answer:

165°

Step-by-step explanation:

Use sum of internal angles formula 180°(n - 2)

<u>For regular 24-gon it is:</u>

180°(24-2) = 3960°

<u>Each angle would be:</u>

3960/24 = 165°

In the figure, Ð1 and Ð3 are vertical angles, and Ð2 and Ð4 are vertical angles.

Ede4ka [16]

Answer:

mÐ4 = 30°

Step-by-step explanation:

Vertical angles are angles that are opposite to each other, thus are said to be equal.

Since,

i. Ð1 and Ð3 are vertical angles

ii. Ð2 and Ð4 are vertical angles

This implies that the measure of Ð1 and Ð3 are congruent. And also the measure of Ð2 and Ð4 are congruent.

So that, if mÐ2 = 30°, it would be expected that mÐ4 has the same measure. This implies that mÐ4 = 30°.

3) When solving a one-step equation, we apply the inverse operation to the value on the _____ of the variable.

sesenic [268]

Answer:

To solve one-step equations, we do the inverse (opposite) of whatever operation is being performed on the variable, so we get the variable by itself. The inverse operations are: Addition and subtraction. Multiplication and division.

Step-by-step explanation:

by it self.

Two separate linear functions are expressed by the graph and by the equation. Select all that apply.

Andre45 [30]

Answer:

First option: The slope is negative for both functions.

Fourth option: The graph and the equation expressed are equivalent functions.

Step-by-step explanation:

<h3> The missing graph is attached.</h3><h3> </h3>

The equation of the line in Slope-Intercept form is:

$y=mx+b$

Where "m" is the slope and "b" is the y-intercept.

Given the equation:

$y=-4x-4$

We can identify that:

$m=-4\\b=-4$

Notice that the slope is negative.

We can observe in the graph that y-intercept of the other linear function is:

$b=-4$

Then, we can substitute this y-intercept and the coordinates of a point on that line, into $y=mx+b$ and solve for "m".

Choosing the point $(-2,4)$ , we get:

$4=m(-2)-4\\\\4+4=-2m\\\\m=-4$

Notice that the slope is negative.

Therefore, since the lines have the same slope and the same y-intercept, we can conclude that they are equivalent.
