When a shape is rotated, it must be rotated around a point.

<em>To determine the location of the new triangle, Sonja must subtract (5,-1) from the coordinates of the original triangle, before rotating by </em>90^o<em>.</em>

<em />

From the question, we have:

C = (5,-1) --- the center of rotation

Let the vertices of the triangle be (x,y).

First, she must subtract the coordinates of the center of rotation from the vertices of the triangle.

This gives:

(x,y) \to (x - 5, y + 1)

Then the vertices are rotated by 90^o

<u />

<u>The rule of </u>90^o<u> rotation is:</u>

(x,y) \to (-y,x)

So, we have:

(x - 5,y + 1) \to (-y - 1,x - 5)

From the attachment, the coordinates of the triangle are: (0,2), (0,5) and (4,2)

After rotation, the coordinates are calculated as follows:

(0,2) \to (-2-1,0-5) \to (-3,-5)

(0,5) \to (-5-1,0-5) \to (-6,-5)

(4,2) \to (-2-1,4-5) \to (-3,-1)

Hence, the coordinates are: (-3,-5), (-6,-5) and (-3,-1)

11h - (2h - 1) = 118
julia-pushkina [17]

You have the following equation:

11h - (2h -1) = 118

In order to solve for h the previous equation you proceed as follow:

11h - (2h -1) = 118

elminate parenthesis by takin into accoun the multilpication of signs

11h - 2h + 1 = 118 simplify similar terms and subtract 1 both sides

9h = 117 divide by 9 both sides

h = 117/9

h = 13

Hence, the solution to the given equation is h = 13

In the 1990s, the number of target stores increased from 420 stores to 914 stores. What was the percent increased in the number
tino4ka555 [31]
Divide 914/420, move the decimal over to the right two places and you'll get approximately 217.5%

EDIT: My mistake, read question wrong.
914-420 = 494
494/420 = 1.17
<u></u>117.62% 
Subtract the difference and divide by original number (: Move decimal place over two places.
