Desperate for help, please! Maths!

Answer 1

Answer:

c) m = 5p-4

Explanation:

Given that function A is : x → +4 → ×2.

A(x) = 2(x+4).

Given that function B is: x → ÷5 → +1.

B(x) = x/5 + 1.

To find the working variables for:

m → Function A → Function B → 2p + 1.

Create this composite function: B(A(x)) = 2(x+4)/5 + 1

Then set x equal to m and solve for the working equation to 2p + 1

_______________

(simplify)

2(m+4)/5 + 1 = 2p + 1

-1 -1

________________

2(m+4)/5 = 2p

÷2 ÷2

___________

(m+4)/5 = p

×5 ×5

_________

(m+4) = 5p

-4 -4

________

m = 5p - 4
