5 pointsWhich is the image of vertex Lafter the triangle is rotated 180 degrees about the origin?
Anastasy [175]

The image of vertex L after the triangle is rotated 180 degrees about the origin= (-2, -1).

Option B.

First let's stae the the original location of the figure on the graph.

From the graph:

L (2, 1)

W(1, -3)

O (-1, -2)

A rotation of 180 degrees about the origin will change the x and y axis of each location to the opposite of those numbers;

Positive numbers becomes negative and negative numbers becomes positive.

The new location for L = L'

L' = (-2, -1)

The new location for W = W'

W' = (-1, 3)

The new location for O = O'

O' = (1, 2)

Hence, the image of vertex L after the triangle is rotated 180 degrees about the origin= (-2, -1).

Option B.

Solve. 14/n+7=10/n-4<br><br> N=5.25<br> N=3.5<br> N=31.5<br> N=30
Ilya [14]

Answer:

n=31.5

Step-by-step explanation:

The given question is:

\frac{14}{n+7}=\frac{10}{n-4}

Cross multiply to get:

14(n-4)=10(n+7)

Expand the parenthesis:

14n-56=10n+70

Group similar terms:

14n-10n=70+56

Combine the like terms

4n=126

Divide both sides by 4

n=\frac{126}{4}

n=31.5
