You can identify points on a graph by looking at them. The x coordinate is the horizontal line. and the vertical line is the y axis
Answer:
960cm³
Step-by-step explanation:
Find the base of the triangle (use phytagoras theorem)
c²= a²+b²
20²= 16²+b²
400=256+b²
b²=400-256
b²= 144
b=

base= 12
Volume: (1/2×b×h)×l
= (1/2×12×16)×10
=(6×16)×10
=96×10
=960cm³

Answer:
K' (-1,10)
L'(0,4)
M'(2,2)
Step-by-step explanation:
To use the mapping rule, substitute x and y with the original values
The coordinates of K are x=-4, and y=5.
Using the mapping rule, x of K' = -4+3 = -1
Using the mapping rule y of K' = 2x5=10
So K' is at the coordinate (-1,10)
The coordinates of L are x =-3, and y =2.
Using the mapping rule, x of L' = -3+3=0
Using the mapping rule y of L' = 2x2=4
So L' is at the coordinate (0,4)
The coorindates of M are x=-1 and y=1
Using the mapping rule, x of M' = -1+3=2
Using the mapping rule, y of M' = 2x1 = 2
So M' is at the coordinate (2,2).
