(x-4)/(3)(x+5)(x-5)

In order for the rational expression to be undefined, the denominator must be equal to 0.

Thus, set 3(x+5)9(x-5)=0

x=5 and -5

Do i need to flip the reciprocal please explain your answer<br> 2y/2 &lt; 10/2
saul85 [17]

Answer:

\displaystyle \large \boxed{y < 5}

Step-by-step explanation:

We are given the Inequality:

\displaystyle \large{ \frac{2y}{2}  <  \frac{10}{2} }

First, we can simplify the expression. On the left side of Inequality, we can cancel 2; on the right side, we can cancel 2 out as well.

Simply, division!

\displaystyle \large{ \frac{ \cancel{2}y}{ \cancel{2}}  <  \frac{ \cancel{10}}{ \cancel{2} }}

2 divides 2 is 1; 2 divides 10 is 5.

\displaystyle \large{ \frac{1y}{1}  <  \frac{ 5}{ 1}}

Generally, it is not recommended to write 1 beside the variable nor write 1 as a denominator.

Simplify the expression:-

\displaystyle \large{ y  <  5}

Therefore, the value of y is less than 5.

Let me know if you have any questions after reading the explanation!
