Answer:

2) Slope=10/3

Step-by-step explanation:

2. Use the equation y2-y1/x2-x1. In this line, I took the points (-4,-5) and (-1,5). Plug this into the equation to get 5--5/-1--4. Simplify this to get 5+5/-1+4. Simplify this to get 10/3. Therefore, the slope is 10/3

4. The equation is y=mx+b where m is the slope and b is the y-intercept. This means that the equation will be 8/3x-5.

If this has helped you please mark as brainliest

Match the expression on the left with the correct simplified expression on the right.
andriy [413]

Given: The expression below

\begin{gathered} (\frac{(3x^3y^4)^3}{(3x^2y^2)^2})^2 \\ (\frac{(3x^4y^2)^4}{(3x^5y^2)^3})^2 \end{gathered}

To Determine: The matching expression to the given expressions

Solution

Let us simplify each of the expressions using exponents rule

\begin{gathered} Exponent-Rule1=(a^m)^n=a^{m\times n} \\ Exponent-Rule2=(\frac{a^m}{a^n})=a^{m-n} \end{gathered}

Applying the exponent rule 1 above to the given expressions

\begin{gathered} (3x^3y^4)^3=3^3x^{3\times3}y^{4\times3}=27x^9y^{12} \\ (3x^2y^2)^2=3^2x^{2\times2}y^{2\times2}=9x^4y^4 \end{gathered}\begin{gathered} (3x^4y^2)^4=3^4x^{4\times4}y^{2\times4}=81x^{16}y^8 \\ (3x^5y^2)^3=3^3x^{5\times3}y^{2\times3}=27x^{15}y^6 \end{gathered}

Applying the exponent rule 2

\frac{(3x^{3}y^{4})^{3}}{(3x^{2}y^{2})^{2}}=\frac{27x^9y^{12}}{9x^4y^4}=\frac{27}{9}x^{9-4}y^{12-4}=3x^5y^8\frac{(3x^{4}y^{2})^{4}}{(3x^{5}y^{2})^{3}}=\frac{81x^{16}y^8}{27x^{15}y^6}=\frac{81}{27}x^{16-15}y^{8-6}=3xy^2

Let us not apply exponent rule 1 above

(\frac{(3x^{3}y^{4})^{3}}{(3x^{2}y^{2})^{2}})^2=(3x^5y^8)^2=3^2x^{5\times2}y^{8\times2}=9x^{10}y^{16}(\frac{(3x^{4}y^{2})^{4}}{(3x^{5}y^{2})^{3}})^2=(3xy^2)^2=3^2x^2y^{2\times2}=9x^2y^4

Hence, the matching is as shown below

A robot can complete 8 tasks in 3/10 hour. Each task takes the same amount of time. How long does it take the robot to complete
Vsevolod [243]

Answer:

Robot will take \frac{3}{80} hour to complete each task.

The robot can complete 26\frac{2}{3} tasks in one hour.

Step-by-step explanation:

We have been given that a robot can complete 8 tasks in 3/10 hour. Each task takes the same amount of time.

To find the time taken by robot to complete each task we will divide total time taken to complete 8 tasks by 8 as:

\text{Time taken by robot to complete each task}=\frac{3}{10}\div 8  

\text{Time taken by robot to complete each task}=\frac{3}{10}\div \frac{8}{1}

Now we will convert division problem into multiplication problem by flipping the 2nd fraction.

\text{Time taken by robot to complete each task}=\frac{3}{10}\times \frac{1}{8}

\text{Time taken by robot to complete each task}=\frac{3}{80}

Therefore, robot will take \frac{3}{80} hour to complete each task.

To find tasks completed by robot in one hour we will use proportions.

\frac{x}{1\text{ hour}}=\frac{8}{\frac{3}{10}}

\frac{x}{1}=\frac{80}{3}

x=\frac{80}{3}

x=26\frac{2}{3}

Therefore, the robot can complete 26\frac{2}{3} tasks in one hour.
