Answer:

The function rule can be written as: f(x) = 2x-3

So, when  we input 3, we replace all of the x's for  3's and have: f(3) = 2(3)-3.

This simplifies to be: f(3) = 3, meaning that 3 is the output.

Hope this helps!

Answer:3

Step-by-step explanation:

The output value is y so set an equation at y=2x-3. Now x is the input value so plug in 3 for x. Two times three is 6 and then you have to subtract three from that. So the output value for an input of 3 is 3.

Answer:

?=91 degrees.

Step-by-step explanation:

There is no x- I'll find ? though.

So, angles in a triangle must equal 180.

180-29-62=89. The last angle in the triangle is 89 degrees.

A straight angle is equal to 180 degrees. ? + 89=180.

180-89=91.

?=91 degrees.

Hope this helped!
