G(x) = 3x + 5
y = 3x + 5
3x = y - 5
x = (y - 5)/3
Therefore, g^-1(x) = (x - 5)/3
Answer:
The coordinate of image triangle is M(-6,-2),N(-1,7) and P(3,4)
Step-by-step explanation:
The area of the polygon is 52.5cm^2.
Area of triangle + Area of rectangle
(b)(h)/2 + (b)(h)
(5)(5)/2 + (8)(5)
25/2 + 40
12.5 + 40
=52.5 centimeters squared
