Answer:
<em>The scale factor is 3</em>
Step-by-step explanation:
<u>Dilations</u>
A dilation is a transformation that produces an image that has the same shape as the original but has a different size.
A dilation is described by the scale factor or constant of dilation and the center of the dilation.
We are given a triangle XYZ of coordinates given in the graph to the left:
X=(-1,1), Y=(-1,4), Z=(-2,1)
It was dilated to triangle X'Y'Z' with coordinates:
X'=(-3,3), Y=(-3,12), Z=(-6,3)
Note each coordinate of the dilated triangle is three times the coordinates of the original triangle, thus the scale factor is 3
Answer:
the correct answer is 3.
Step-by-step explanation:
3×3×3= 27
No 'real' numbers can do that job.
The two numbers are complex.
They are ...
<em>1 + i √3</em>
and
<em>1 - i √3</em> .
Answer:
( x, y ) = ( 4, 1/3)
Step-by-step explanation:
x - 3y = 3
2x +9y = 11
1. substitute the value of x
x= 3 + 3y
2x + 9y = 11
2. solve equation
2 (3 + 3y) +9y = 11
3. substitute the value of y
y = 1/3
4. solve equation
x = 3 + 3 x 1/3
x = 4
5. check solution
(x, y) = ( 4, 1/3 )
check x ----> 4 - 3 x 1/3 = 3
check y ------> 2 x 4 + 9 x 1/3 = 11
for x----> 3=3
for y----> 11=11
Assuming that there was no error in you typing, the exponent is 1 and the coefficient is -2
