Answer:

C. (-3, 1)

Step-by-step explanation:

$- x + y = 4 \\ \therefore \: y = x + 4...(1) \\ \& \: 3x - 4y = - 13....(2) \\ substituting \: y = x + 4 \: in \: equation \: (2) \\ 3x - 4(x + 4) = - 13 \\ 3x - 4x - 16 = - 13 \\ - x = 16 - 13 \\ - x = 3 \\ \huge \red{ \boxed{x = - 3}} \\ plug \: x = - 3 \: in \: equation \: (1) \\ y = - 3 + 4 \\ \huge \purple{ \boxed{y = 1}} \\ \\ \orange{ \boxed{ \bold {\therefore \: (x, \: \: y) = ( - 3, \: \: 1)} }}$

Which is equivalent to cos-(0)? Give your answer in radians.

Setler [38]

Remember that cos(0) represents the x value of a point on the unit circle. The period for the unit circle is 2π in radians which means that adding or subtracting 2π will get you back to the same point which has the same cosine.

Examples: cos(2π),cos(100π),cos(60π)

For what value of x must ABCD be a parallelogram?

mel-nik [20]

Here is your answer

$\bold{x= 6}$

REASON:

Theorem used: The diagonals of a parallelogram bisect each other.

Let diagonals AC and BD bisect each other at O

So, OA=OC

Now,

3x=4x-6 [OA=3x and OC=4x-6]

4x-3x= 6

x= 6
