Answer: y=2x+1

Step-by-step explanation:

Let's use point-slope form which is y-y1 = m(x-x1)

Let's substitute these in.

y-3 = 2(x-1)

y-3 = 2x-2

y = 2x+1

When graphed on desmos it looks like this:

Answer:

see explanation

Step-by-step explanation:

Using the trigonometric identities

• tanx = $\frac{sinx}{cosx}$

• sin²x + cos²x = 1 ⇒ sin²x = 1 - cos²x

Consider the left side

$\frac{tan^2x-sin^2x}{tan^2x}$

= $\frac{tan^2x}{tan^2x}$ - $\frac{sin^2x}{tan^2x}$

= 1 - cos²x

= sin²x = right side ⇒ verified

PLSSS HELP GIVING BRAINLIEST <br>Find the value of x. 160° (10x + 50) O A. 11 B. 13 O c. 4 D. 21

Answer:

A. 11

Step-by-step explanation:

Since the angles are vertical angles (share a vertex) they are equal in measure.

160 = 10x + 50

subtract 50 from both sides

110 = 10x

divide both sides by 10

x = 11

Answer:

(6x6x6x6) x (6x6x6)

Step-by-step explanation:

6 to the power of four is just 6 multiplied to itself 4 times.

6 to the power of three is just 6 multiplied to itself 3 times.

So, you would be multiplying 6, 7 times.

You could check it with a calculator. - 6^4 x 6^3 = 279936.

6^7 = 279936.
