If f(x)=2x-4, what would be the answer if f(3)-1??
Vinil7 [7]

Answer:

1

Step-by-step explanation:

We have the function

f(x) = 2x - 4

and we want to know the value of f(3) - 1.

The first step is to find f(3) ; we can subtract 1 from it at the end! But what does f(3) mean?

Basically, we're saying <em>"what is the value of the function when </em>x = 3<em> ?"</em>

So, we simply replace x with 3 in the function, and we get:

f(3) = 2\times 3 - 4 = 2.

Finally, we subtract 1 to find f(3) - 1 = 1.

Find the value of x in each case:
goblinko [34]

Answer:

x = 11

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ FEB and ∠ DEB are adjacent angles and supplementary, thus

∠ FEB = 180 - 4x , so

180 - 4x + x = 147, that is

180 - 3x = 147 ( subtract 180 from both sides )

- 3x = - 33 ( divide both sides by - 3 )

x = 11
