Answer:
(-6, 6)
Step-by-step explanation:
The coordinates of B to start with is
(-2, 2)
To dilate this by a factor of 3....
-2 * 3 = -6
2 * 3 = 6
The new coordinates of B' would be
(-6, 6)
A few things to know:
- The number 3 is called a "<u>scale factor</u>"
- Dilation means we are multiplying all the (X, Y)'s by the scale factor
- If the scale factor is <u>greater than 1</u>, the size of the shape overall increases
- If the scale factor is <u>less than 1</u>, the size of the shape overall decreases
- If the scale factor is <u>negative</u>, the shape size stays the same. The shape just rotates 180 degrees and moves to the opposite quadrant.
Hello!
To find the area, you take one side, (16) and multiply it by that number..
So, 16 * 16 = 256.
The area of a square with 16in sides is 256.
Hope this helps! ☺♥
Answer:
x= -6
Step-by-step explanation:
3x+4= 2 (x - 1)
3x+4= 2x -2
Subtract 4 from both sides of the equation
Simplify
Subtract 2x from both sides of the equation
Simplify
= -6
In a survey with 60 people, each people would get 1/60th of the chart which has 360 degrees, so everyone would get 360/60=6 degrees
and 13 people would get 13*6=78 degrees!
