Answer:

A, B, and D

Step-by-step explanation:

Substitute all the coordinates into the equation. (x, y)

3(-2) - (-7) = 1

-6 - (-7) = 1

1 = 1

3(-1) - (-4) =1

-3 - (-4) = 1

1 = 1

3(0) - (1) = 1

0 - (1) = 1

-1 does not equal 1

3(3) - (8) = 1

9 - (8) = 1

1 = 1

Find all values of x in the interval [0,2π] that satisfy the equation sin2x=cosx. enter your answers as a list of numbers separa

yuradex [85]

$\sin(2x) = \cos(x) \\ 2 \sin(x) \cos(x) = \cos(x) \\ \cos(x) (2 \sin(x) - 1) = 0$
so
$\cos(x) = 0 > > > x = \frac{\pi}{2} + k\pi \\ \sin(x) = \frac{1}{2} > > > x = \frac{\pi}{6} + 2k\pi \\ or \: x = \frac{5\pi}{6} + 2k\pi$
$x = \frac{\pi}{2} or \frac{3\pi}{2} \\ x = \frac{\pi}{6} or \frac{5\pi}{6}$

Use the distributive property to factor out y. 5y-3y+12

ladessa [460]

5y - 3y + 12

Because there is not a common factor between the three terms in it's current state, we must simplify.

2y + 12

Now, we can simplify using the distributive property.

Factor 2.

<h3>2(y + 6) is the factored form of the original expression.</h3>

There are 6 blue socks, 7 white socks, and 8 gray socks in a drawer. If you pick sock without looking, what is the probability i

BigorU [14]

Answer:

Pr(blue) = 2/7

Step-by-step explanation:

Blue = 6

White = 7

Gray = 8

Total socks = 6+7+8 =21

Probability of picking blue = number of blue ➗ total number of socks

Pr(blue) = 6/21

Divide both by 3 to make the fraction to the lowest term.

Pr(blue) = 2/7

I hope this was helpful, please mark as brainliest
