Answer:
F ( 2 , -2)
Step-by-step explanation:
Answer:
y=-5,x=2
Step-by-step explanation:
3x+3y=-9________________eqn 1
3x-3y=21________________eqn 2
using elimination method
3x+3y=-9
-
3x-3y=21
subtract equation 2 from equation 1
0+6y=-30
6y=-30
y=-30/6
y=-5
substitute the value of y in equation 1
3x+3y=-9
3x+3(-5)=-9
3x-15=-9
3x=-9+15
3x=6
x=6/3
x=2
Answer:
Yes
Step-by-step explanation:
they were just dilated differently
Answer:
16 cm^2
Step-by-step explanation:
Given
-- Bigger Triangle
-- Smaller Triangle
--- Scale factor
Area of CBD = 9
Required
Determine the area of CAE
The area of triangle CBD is:
The area of CAE is:
Where:
and
The above values is the dimension of the larger triangle (after dilation).
So, we have:
Re-order
Recall that:
Hence, the area is 16 cm^2
