Answer:
x=5
Step-by-step explanation:





Answer:
a. 96 square units
Step-by-step explanation:
The figure is a rectangle with width AB = (20-12) = 8 units and height BC = (20-8) = 12 units.
The area of the rectangle is (8 units)×(12 units) = 96 square units.
Answer:
(x, y) → (x - 3, y + 5 )
Step-by-step explanation:
A shift of 3 units to the left means subtract 3 from the original x- coordinate.
A shift of 5 units up means add 5 to the original y- coordinate.
Thus the rule representing the translation is
(x, y ) → (x - 3, y + 5 )
-10x - 15y = -30
-10x + 30 = 15y
(30 - 10x) / 15 = y
(30/15) - (10x/15) = y
2 - 2x/3 = y
Answer: y = -2x/3 + 2 or y = 2- 2x/3
