I can’t see the numbers but here is a way to help you solve. Domain go from left to right and range bottom to the top
Answer:
24
Step-by-step explanation:
A triangle is a three sided polygon with three edges and three vertices
There are different types of triangles. They include :
- Right angled triangle - one of the angles measure 90 degrees
- equilateral triangle - all three sides of the triangle are equal
- isosceles triangle - two sides of the triangle are equal
Area of a triangle = 1/2 x ( base x height)
1/2 x (6 x 8) = 24 ft²
The ratio of coordinates in the image to the coordinates of the original will tell you the dilation factor when diation is about the origin (as here).
Jx'/Jx = -2/-3 = 2/3
This same ratio is true for the other 5 coordinate values, so we know that ...
... the scale factor used in the dilation is 2/3.
_____
Jy'/Jy = -8/-12 = 2/3
Kx'/Kx = -4/-6 = 2/3
Ky'/Ky = -10/-15 = 2/3
Lx'/Lx = -6/-9 = 2/3
Ly'/Ly = -8/-12 = 2/3
The incorrect answer is B.
All you have to do is plug in x to the formulas and see if the are equal.
4x - 2 = 3x + 6
4(8) - 2 = 3(8) + 6
30 = 30
CORRECT
The second is not only not equal, but it is the wrong kind of formula for what you are trying to prove there.
Hope that helps!
SSS (Side, side, side), ASA (Angle, side, angle), SAS (Side, angle, side), AAS (Angle, angle, side), or HL (Hypotenuse, leg). Make sure those factors are congruent with eachother.
