The values of p for which the equation px = 10 have a solution −5; 1; 20 is -2, 10, 
<u>Solution:</u>
Given, equation is px = 10.
We have to find the values of p for which solutions of given equations becomes -5, 1, 20.
We just need to substitute -5, 1, 20 in given equation as x, to values of p.
Now, For -5 ⇒ p(-5) = 10 ⇒ -5p = 10 ⇒ p = -2
For 1 ⇒ p(1) = 10 ⇒ p = 10
For 20 ⇒ p(20) = 10 ⇒ 20p = 10 ⇒ p = 
Hence, the values of p are -2, 10,
for the solutions -5, 1, 20 respectively.

Celine has already knitted 0.8 meters. Her final result should be 1.2 meters.
To calculate how many meters Celine has to knit we should subtract the alreadu knitted length of scarf from the entire length. This give the equation:\
X=1.2m-0.8m
X is the unknown
X=0.4 meters

What is G(x) ?</h2>
Composition of a function is done by substituting one function into another function. For example, f [g (x)] is the composite function of f (x) and g (x). The composite function f [g (x)] is read as “f of g of x”. The function g (x) is called an inner function and the function f (x) is called an outer function.
