Question

P(m)=m/5+8

Answer 1

M(p) = 5p-40 (apex) ....

Answer 2

Answer:

C. M(p)= 5p-40

Step-by-step explanation:

Here, the given function,

$P(M)=\frac{M}{5}+8$

$\implies P=\frac{M}{5}+8$

$P-\frac{M}{5}=8$   ( Subtracting $\frac{M}{5}$ on both sides )

$-\frac{M}{5}=8-P$  ( Subtracting P on both sides )

$\frac{M}{-5}=8-P$

$M=-5(8-P)$           ( By cross multiplication )

$M=-40+5P$     ( By distributive property )

$M=5P-40$       ( Commutative property )

$\implies M(P) = 5P-40$

Which is the required function in which the input value is number of problems.

Option C is correct.
