Answer:

\sf \dfrac{3}{{z-3} }

Explanation:

\Longrightarrow \sf \dfrac{1}{z}  \div  \dfrac{z-3}{3z}

apply the theorem when \dfrac{a}{b}  \div \dfrac{c}{d} then \dfrac{a}{b}  \times \dfrac{d}{c}

\Longrightarrow \sf \dfrac{1}{z}  \times  \dfrac{3z}{z-3}

Join the fractions

\Longrightarrow \sf \dfrac{3z}{z({z-3)} }

Cancel out common factor z

\Longrightarrow \sf \dfrac{3}{{z-3} }

I really need help someone please
Olegator [25]
The factorization of A is y = (x - 8)(x + 7).
The factorization of B is y = (x + 1)(x - 4)(x - 5)

In order to find these, you must first find where each graph crosses the x-axis. In the first problem it does so at 8 and -7. In order to find the correct parenthesis for those, you need to write it out as a statement and then solve for 0. 

x = 8 ---> subtract 8 from both sides
x - 8 = 0
This means we use (x -  8) in our factorization. 

You then need to repeat the process until you have all the pieces. In the second problem, there will be 3 instead of 2 since it crosses the axis 3 times.

This means all the numbers greater than 65.

Do not include 65 because it is not a greater than or equal to symbol.

Hope this helps!

If not, I am sorry.

Write the compound inequality shown by the graph.<br> 20. 2QHHH<br> UNIT 4
belka [17]

Answer:

x ≥ 9 and x < 5

Step-by-step explanation:

See the line graph of a compound inequality shown in the attached photo.  

Inequality has two parts. The right-hand part is shown by an arrow that is more than 9 and including 9.

So, the equation of inequality for this part is x ≥ 9.

Again, the left-hand part of the inequality graph shows another arrow which is less than 5 but not including 5.

So, the equation of inequality for this part is x < 5

Therefore, compound inequality is x ≥ 9 and x < 5 (Answer)
