Answer:
-23
Step-by-step explanation:
You combine the numbers
8+(-13)-18=
add 8 to -13
-5
add -18 to -5
-23
Answer:
8
Step-by-step explanation:
all numbers must be positive when you have the lines on the side
Answer:
1 : 50
Step-by-step explanation:
1.50 : 75
Multiply by 2 so there are no decimals.
3 : 150
Divide by 3 to simplify.
1 : 50
First of all, we need to know the coordinate of ABCD and A'B'C'D', so the coordinate of ABCD will be:
A(-3,5)
B(-1,2)
C(-2,-1)
D(-5,-3)
Then, coordinate of new figure will be:
A'(-7,8)
B'(-5,5)
C'(-6,2)
D'(-9,0)
Next,
Let's try all the translations:
(x,y) to (x+4,y+3)
A(-3,5) to A'(-3+4, 5+3)
A(-3,5) to A'(1,8)
Which is not right because A' need to be (-7,8)
(x,y) to (x-4,y+3)
A(-3,5) to A'(-3-4,5+3)
A(-3,5) to A'(-7,8)
B(-1,2) to B'(-1-4,2+3)
B(-1,2) to B'(-5,5)
C(-2,-1) to C'(-2-4,-1+3)
C(-2,-1) to C'(-6,2)
D(-5,-3) to D'(-5-4,-3+3)
D(-5,-3) to D'(-9,0)
Yay, we found the answer. As a result, (x,y) to (x-4,y+3) is your final answer. Hope it help!
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
