Answer:

A. x = 68, y = 75

Step-by-step explanation:

So you see how those three angles all make a straight line? that's called complementary, where it all makes 180˚.

So, you know that...

(x-1)˚ + 40˚ + (y-2)˚ = 180˚

I'm not sure what that 74˚ is about, but what I would do is plug in the options until you get 180 degrees.

In this case, its the first option, A.

(68-1)˚ + 40˚ + (75-20)˚ = 180˚, which is true! so its A.

<h3>Answer: f( h(x) ) = 2x - 4</h3>

Work Shown:

f(x) = x - 7

f( h(x) ) = h(x) - 7

f( h(x) ) = 2x+3 - 7

f( h(x) ) = 2x - 4

Explanation:

In the second step, I replaced every x with h(x). In the next step, I replaced the h(x) on the right hand side with 2x+3. From there I combined like terms.
