-2 + Y = 8
Y = 10
Plug in Y to the first equation, 10 + 4 = X
X = 14
Is there any sums that you needed to solve this with?
8.a)
A= (1,1) A’= (3,3)
B= (4,6) B’= (12,18)
C= (6,1). C= (18,3)
8b.)
A= (1,1) A’(0,5,0.5)
B= (4,6) B(2,3)
C= (6,1). C(3,0.5)
Hope this helped ! :)
In order to find the volume, you have to find the volume ratio. To find the volume ratio you have to cube the scale factor. 1/2 cubed is 1/8. Now to find the volume, you multiply the volume ratio by the volume of the original prism.
160x1/8= 20
The answer is 20cm3
-6 < x + 1 ≤ 1
<u>-1 -1 -1</u>
-7 < x ≤ 0
-7 < x or x ≤ 0
x > -7 or x ≤ 0
