Question

$p(x) = 5x - \pi \:by x = \frac{4}{5}$

Answer 1

Answer:

$\frac{6}{7}$

Step-by-step explanation:

Given :

$p(x) = 5x - \pi$

$x = \frac{4}{5}$

Solution :

We know that, $\pi$ ≈ $\frac{22}{7}$

$p(x) = 5x - \pi$

$p(\frac{4}{5}) = 5(\frac{4}{5}) - \frac{22}{7}$

$p(\frac{4}{5}) = 4 - \frac{22}{7}$

$p(\frac{4}{5}) = \frac{28 - 22}{7}$

$p(\frac{4}{5}) = \frac{6}{7}$

∴ When $x = \frac{4}{5}$ , $p(x) = 5x - \pi = \frac{6}{7}$
