Answer:
y = -2/3x - 3
Step-by-step explanation:
y = -2/3x + b
-1 = -2/3(-3) + b
-1 = 2 + b
-3 = b
y = -2/3x - 3
Answer:
-1 5/6, 1 2/3, -2.1, -2.2
Step-by-step explanation:
Rember the numbers are neggative, then convert -1 2/3 to -1 4/6.
The function is decreasing from -6 to -3, that is, on the interval (-6,-3), and again on the interval (1, infinity).
The function is increasing on (-3,1).
No local or absolute minimum.
(1,4) is an absolute max.
Answer:
45 square units.
Step-by-step explanation:
Applying the pythagoras theorem:
Base of the bigger triangle =
=
= 12 units
Area of a triangle is given by
× base × height
The area of the bigger triangle is
× 12 × 9 = 54 square units.
The area of the smallest triangle is
× (12 - 10) × 9 = 9 square units.
The area of the figure( required triangle) is 54 - 9 = 45 square units.
