Step-by-step explanation:

(a)

Given

f(x) = 2x + 1

To find f(2) substitute x = 2 into f(x)

f(2) = 2(2) + 1 = 4 + 1 = 5

(b)

let y = f(x) and rearrange making x the subject, that is

y = 2x + 1 ( subtract 1 from both sides )

y - 1 = 2x ( divide both sides by 2 )

= x

Change y back into terms of x with x = (x)

(x) =

(c)

Substitute x = 7 into (x) , that is

(7) = = = 3

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.
