Solve 10+6(-9-4x)=10(x-12)+8
Anna71 [15]

10 + 6(-9 + -4x) = 10(x + -12) + 8

10 + (-9 * 6 + -4x * 6) = 10(x + -12) + 8

10 + (-54 + -24x) = 10(x + -12) + 8

Combine like terms: 10 + -54 = -44

-44 + -24x = 10(x + -12) + 8

Reorder the terms:

-44 + -24x = 10(-12 + x) + 8

-44 + -24x = (-12 * 10 + x * 10) + 8

-44 + -24x = (-120 + 10x) + 8

Reorder the terms:

-44 + -24x = -120 + 8 + 10x

Combine like terms: -120 + 8 = -112

-44 + -24x = -112 + 10x

Solving

-44 + -24x = -112 + 10x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-10x' to each side of the equation.

-44 + -24x + -10x = -112 + 10x + -10x

Combine like terms: -24x + -10x = -34x

-44 + -34x = -112 + 10x + -10x

Combine like terms: 10x + -10x = 0

-44 + -34x = -112 + 0

-44 + -34x = -112

Add '44' to each side of the equation.

-44 + 44 + -34x = -112 + 44

Combine like terms: -44 + 44 = 0

0 + -34x = -112 + 44

-34x = -112 + 44

Combine like terms: -112 + 44 = -68

-34x = -68

Divide each side by '-34'.

x = 2

Simplifying

x = 2

Find the sine, cosine, and tangent of 120 degrees. (5 points) Sin 120 degrees = square root of 3 divided by 2, cos 120 degrees =
salantis [7]
120° will be found on in the second quadrant of the unit circle. Specifically, the reference angle will be 60°. This is because the angle measurement starts from the positive x axis, and rotates 120° counter-clockwise. The angle formed at this point between the line and the x-axis (negative direction) is 60°.

The special right triangle formed will have a hypotenuse of 1, and a reference angle of 60°.
We know that the adjacent line, the line opposite the 30° angle, will be 1/2 the hypotenuse, or -1/2. Negative because it goes in the negative x direction.
The opposite end, or vertical side, will be √3/2.

sin(120) = opposite/hypotenuse = √3/2 ÷ 1 = √3/2

cos (120) = adjacent/hypotenuse = (-1/2) / 1 = -1/2

tan (120) = opposite / adjacent = (√3/2) / (-1/2) = -√3
