B I did this to:) it’s pretty easy once u get the hang of it
Answer:
The images are;
A’ (5,2) B’ (2,1) and C’ (1,3)
Step-by-step explanation:
Firstly, we want to reflect across the x-axis
When we reflect a point (x,y) over x-axis, we get (x,-y)
So;
A ( 2,5) becomes (2,-5)
B (1,2) becomes (1,-2)
C ( 3,1) becomes (3,-1)
Then we proceed to rotate 90 degrees counterclockwise about the origin
Here we have;
(x,y) becomes (-y,x)
(2,-5) becomes (5,2)
(1,-2) becomes (2,1)
(3,-1) becomes (1,3)
Answer:
x=11.8
Step-by-step explanation:
17.2/4.3=4
34.4/4=8.6
47.2/4=11.8
P = 7n + 20
consider the results of figure to perimeter
1 → 27
2 → 34
3 → 41
the difference between perimeters is 41 - 34 = 34 - 27 = 7
multiplying the figure number by the difference gives
1 × 7 = 7 ← require 27 thus add 20
2 × 7 = 14 ← require 34 thus add 20
3 × 7 = 21 ← require 41 thus add 20
Hence the required equation is
P = 7n + 20
