Answer:

  B.  Square

Step-by-step explanation:

When in doubt, it can help to plot the points on a graph.

__

By looking at the coordinate values, you see that the first two points have the same y-coordinate (0) and the other two points have the same y-coordinate (-4). These points are on horizontal lines that are 4 units apart.

Looking at the x-coordinates, you see that one pair of points has x-coordinates 4, and the other pair has x-coordinates 8. That is, these pairs of points are on vertical lines that are 4 units apart.

Vertical and horizontal lines are at right angles to each other. That means the figure must be a rectangle or square. The lengths of the sides are all 4 units, so the figure is a square.

3 (6+3n) = 5n + 18 + 3n
amid [387]

Answer:

n = 0

Step-by-step explanation:

Multiply parenthesis by 3 and get:

1.) 18 + 9n = 5n + 18 + 3n

Then cancel the equal terms:

9n = 5n + 3n

Collect like terms:

9n = 8n

Move variable to the left:

9n - 8n = 0

n + 0

Plugin the value of 0 into x:

3 (6 + 3 x 0) = 18

5 x 0 + 3 x 0 + 18 = 18

*If the plugged in value have the same result than the answer is correct because 18 + 18.

Solve for x in the following figure. Choose the appropriate result.
pickupchik [31]

Answer:

d

Step-by-step explanation:

all of the angles add up to equal 180 so we setup the equation as 45+3x=180

first you subtract each side by 45

135=3x

then you divide each side by 3 and get that

x=45

Answer:

D. Yes The Triangles ARE ≅

Step-by-step explanation:

By definition equilateral triangles have all equal angles and sides. Since they share a side that means one of each triangle's sides are congruent. Using the transitive property (if side a ≅ side b and side b ≅ side c, then side a ≅ side c), you can prove that all other sides are congruent or equal in measure, no matter how you pair them.

What is the average rate of change from −3 to 0 of the function represented by the graph?
aleksandrvk [35]

Answer:

-0.5

Step-by-step explanation:

The average rate of change from a to b:

[f(b) - f(a)]/(b - a)

Look in the graph for the function values at x = -3 and x = 0.

f(-3) = 2

f(0) = 0.5

average rate of change =

= [f(-3) - f(0)]/(-3 - 0)

= [2 - 0.5]/(-3)

= 1.5/(-3)

= -0.5
