Answer:
-32x-22y
Step-by-step explanation:
4x + 2y - 6(6x - 4y)
Use distributive property
4x + 2y - <u>6(6x - 4y)</u>
4x + 2y - 36x -24y
-32x-22y
The slope-point form:
The formula of a slope:
We have the points (7, -8) and (-4, 6). Substitute:
Answer:
False
Step-by-step explanation:
2cos^2(4x) - 1 = cos(8x)
cos(8 *pi/12) = cos(2pi/3) = cos(pi - pi/3) = - cos(pi/3)= 1/2, which is not 0
cos(8x) = 0
==> 8x = 0 or pi
==> x = 0 or pi/8
Answer:
Step-by-step explanation:
We use trig to answer these questions:
sin x = opposite side of a triangle / hypotenuse
cos x = adjacent side / hypotenuse
Construct a right triangle with hypotenuse 4 m and lower angle 68 degrees.
The height of the top of the ladder is then defined by:
sin 68 degrees = height / 4 m, which yields (4 m)(sin 68) = height =
3.71 m
and the distance of the bottom of the ladder from the wall as follows:
cos 68 degrees = horizontal distance / hypotenuse =
1.50 m
Answer: x=64
Step-by-step explanation: Since the lines are perpendicular, as is apparent by the 90 degree angles, we know that x must be 90-26=64
