Answer:
The coordinate of pre-image is, B(3 , -9).
Step-by-step explanation:
Given an image point has coordinate B'(7, -4).
We have to find the coordinates of its pre-image:
The rule of translation on pre-image (x, y) is given by;

then;
(7, -4) = (x+4, y+5)
on comparison we have;
x+4 = 7 and y + 5 = -4
First solve for x;

Subtract 4 from both sides we have;
x + 4 -4 =7-4
Simplify:
x = 3
To solve for y;
y+5 = -4
Subtract 5 from both sides we get;
y = -9
Therefore, the coordinate of pre-image is, B(3, -9)
From the number given is appears the rule is y = 2x + 1
This works for all three:
17 = 2(8) + 1
1 = 2(0) + 1
15 = 2(7)+1
Answer:
24 units
Step-by-step explanation:
Perimeter of Polygon PQRSTU = sum of all its side lengths = PQ + QR + RS + ST + TU + PU
PQ = |-4 -(-2)| = 2 units
QR = |4 - 2| = 2 units
RS = |-2 - 2| = 4 units
ST = |2 -(-2)| = 4 units
TU = |2 -(-4)| = 6 units
PU = |4 - (-2)| = 6 units
Perimeter of Polygon PQRSTU = 2 + 2 + 4 + 4 + 6 + 6 = 24 units
