Answer:
yes
Step-by-step explanation:
There are several ways to go at this.
My first choice is to use a graphing calculator. It shows the function has a zero at x=5, so x-5 is a factor.
Another good choice is to use synthetic division (2nd attachment). If the remainder is zero, then x-5 is a factor. It is and it is.

You can also evaluate the function at x=5. The remainder theorem tells you that if the value is zero, then x-5 is a factor. Evaluating the polynomial written in Horner form is a lot like synthetic division.
(((x -4)x -15)x +58)x -40 for x=5 is ... (-10·5 +58)5 -40 = 40-40 = 0
The value of h(5) is zero, so x-5 is a factor of h(x).
<em>Volumes of 2% Solution = </em><em>5 ml</em>
<em>Volumes of 10% Solution = </em><em>5 ml</em>
Simultaneous Linear Equations could be solved by using several methods such as :
- <em>Elimination Method</em>
- <em>Substitution Method</em>
- <em>Graph Method</em>
If we have two linear equations with 2 variables x and y , then we need to find the value of x and y that satisfying the two equations simultaneously.
Let us tackle the problem!
<em>Let:</em>
<em>Volumes of 2% Solution = x</em>
<em>Volumes of 10% Solution = y</em>
<em>Total Volume = 10 ml</em>
→ <em>Equation 1</em>
<em>The nurse needs to mix 2% solution with 10% solution to get 10 ml of the prescribed 6% solution</em>.
→ <em>Equation 2</em>
<em>Equation 1 - Equation 2:</em>
<em>Volumes of 2% Solution = </em><em>5 ml</em>
<em>Volumes of 10% Solution = </em><em>5 ml</em>
