Answer:

x = -2y + 12

Step-by-step explanation:

Let's solve for x.

x + 2y = 12

Step 1: Add -2y to both sides.

x + 2y + −2y = 12 + −2y

x = −2y + 12

A circle with a radius of 5 is inscribed in a equilateral triangle. What is the area of the triangle's area minus the circle's a

Aleonysh [2.5K]

First off, the area of the circle would be 78.54

Now, you would do (area of the triangle)--- AT-78.54=answer

I don't know how to find the area of the triangle with just the circle's radius, so this is all I can do. I'm sorry!

Find all solutions of the equation sin^2 x=2sinx+3

Mashutka [201]

$\sin^2x=2\sin x+3$
$\sin^2x-2\sin x-3=0$
$(\sin x-3)(\sin x+1)=0$

which means either $\sin x=3$ or $\sin x=-1$ . The equation has no solution, since $\sin x$ is always bounded between -1 and 1. The second has one solution at $x=-\dfrac\pi2$ , and any number of complete revolutions will also satisfy this equation, so in general the solution would be $-\dfrac\pi2+2k\pi$ where $k$ is any integer.

So you could choose $A=-\dfrac\pi2$ and $B=2$ .

Answer:

A. 49.

Step-by-step explanation:

Given equation:

-11 2/3 * (-4 1/5)

Simplify, then solve:

-11 2/3 * (-4 1/5)
= -35/3 * (-21/5)
= $\frac{-35 * (-21)}{3 * 5}$
= 735/15
= 49.

Your answer is A. 49.
