The point (-3,-1) is the midpoint of (x,y) and (5,4). Find the point (x,y).

nirvana33 [79]

Answer:

(-11, -6)

Step-by-step explanation:

Find the distance between the midpoint, (-3, -1) and (5, 4). This can be calculated by finding the difference between the x coordinates and y coordinates.

-3 - 5 = -8 (distance between x coordinates)

-1 - 4 = -5 (distance between y coordinates)

Find the point (x, y) by subtracting 8 from the midpoint's x value, and then subtracting 5 from the midpoint's y value.

-3 - 8 = -11

-1 - 5 = -6

So, the point (x, y) is (-11, -6)

6cos x-6sin x=3.sqrt6

Yakvenalex [24]

Divide by 6
$cos x - sin x = \frac{\sqrt{6}}{2}$

Square both sides
$cos^2 x -2 sin x cos x + sin^2 x = \frac{3}{2}$

Simplify Left side using Trig identities: (Pythagorean, Double Angle)
$1 - sin (2x) = \frac{3}{2}$

Solve for x:
$sin (2x) = -\frac{1}{2} \\ \\ 2x = \frac{7 \pi}{6}, \frac{11 \pi}{6} \\ \\ x = \frac{7 \pi}{12}, \frac{11 \pi}{12}$
