Answer:

Step-by-step explanation:

The slope (m) can be found using the formula ...

m = (y2 -y1)/(x2 -x1)

Any pair of points will do. We can use the first two.

m = (2 -(-10))/(17 -15) = 12/2

m = 6

The slope of the line is 6.

What is the trigonometric ratio for cosC?

valentina_108 [34]

Answer:

the ratio of the adjacent side to the hypotenuse is a function of the angle c, so we can write the symbol as cos(c) = value. 90

Step-by-step explanation: You can also see that 40 + 41 + 9 = 90. hope this helps

Answer: They are inverses of each other

============================================================

Explanation:

We need to check two things:

f(g(x)) = x
g(f(x)) = x

If both of those equations are true, then f and g are inverses of each other.

----------------

Part 1

$f(x) = -3x-12\\\\f(g(x)) = -3( g(x) )-12\\\\f(g(x)) = -3\left( \frac{-12-x}{3} \right)-12\\\\f(g(x)) = 12+x-12\\\\f(g(x)) = x\\\\$

So far, so good. Now we need to check the other equation mentioned.

------------------

Part 2

$g(x) = \frac{-12-x}{3}\\\\g(f(x)) = \frac{-12-( f(x) )}{3}\\\\g(f(x)) = \frac{-12-( -3x-12 )}{3}\\\\g(f(x)) = \frac{-12+3x+12}{3}\\\\g(f(x)) = \frac{3x}{3}\\\\g(f(x)) = x\\\\$

That works out as well. Both equations mentioned are true, which confirms the two original functions are inverses of one another.
