Answer:

y = -x +b

Step-by-step explanation:

The equation of a line is

y = mx+b where m is the slope and b is the y intercept

y = -1 x +b

Substitute the point into the equation

1 = -1*2 +b

1 = -2 +b

Add 2 to each side

1+2 = -2+b+2

3 =b

y = -x +3

Answer:

1/26

Step-by-step explanation:

Total no. of tiles = 26

In each tile , a different alphabet is written.

And we need 3 tiles (in which A , B & C are written in it) in one try.

So the probability of choosing tiles with letters A , B & C ( in one try ) = 1/26

What is the smallest positive degree angle measure equivalent to sin^-1 (0.391)?

natta225 [31]

Given:

The value is:

$\sin^{-1}(0.391)$

To find:

The smallest positive degree angle measure equivalent to $\sin^{-1}(0.391)$ .

Solution:

We have,

$\sin^{-1}(0.391)$

Using the scientific calculator, we get

$\sin^{-1}(0.391)=23.0167366398^\circ$

$\sin^{-1}(0.391)\approx 23^\circ$

Therefore, the smallest positive degree angle measure equivalent to $\sin^{-1}(0.391)$ is 23 degrees.
