We are given with two equations and is asked to determine the solution of the system of linear equation. via elimination, we add the two equations to eliminate 3x, this means y should be equal to 9 and from the first equation, x should also be equal to 9, too
The other dude most likely attached a virus
The answer is 0.56464247339
Across from the right angle is the hypotenuse
Across from where the two long sides end is the opposite
And the other side is the adjacent
Sin (opposite/hypotenuse) cos(adjacent/hypotenuse) tan (opposite/adjacent)
8x5=40
So the car is 40 inches long
Answer:
C. f has a relative maximum at x = 1.
Step-by-step explanation:
A. False. f(x) is concave down when f"(x) is negative. f"(x) is the tangent slope of the graph, f'(x). So f(x) is concave down between x = -1.5 and x = 1.5.
B. False. f(x) is decreasing when f'(x) is negative. So f(x) is decreasing in the intervals x < -3 and 1 < x < 2.
C. True. f(x) has a relative maximum where f'(x) = 0 and changes from + to -.
