Turn both fractions to improper.

2 2/3 = multiply whole number by the denominator. which is 6. now add the numerator with 6. and this equals to 8. now use 8 as a numerator and keep the same denominator. so it should be 8/3. 

Do the same thing for 4 1/3 and you get 13/3.

now you both have improper fractions. 

= 8/3 divided by 13/3 . 

flip the second fraction, : 13/3, and this is called reciprocal. 

And turn the division sign to multiplication. 

= 8/3 x 3/13

multiply both numerators and denominators.

8 x 3 = 24 

3 x 13= 39

now you have 24 / 39

you can further simplify it. both are divisible by 3.

24 divided by 3 is 8

39 divided by 3 is 13

Now your fraction remain as: 8/13.

This is the farthest it can simplify. so your answer is 8/13.

thank you for posting your answer here on brainly, have a great day!

Please mark as brainliest so i can answer more! :)

Let y′′′−9y′′+20y′=0. find all values of r such that y=erx satisfies the differential equation. if there is more than one correc
DerKrebs [107]

we are given

differential equation as

y'''-9y''+20y'=0

we are given

y=e^{rx}

Firstly, we will find y' , y'' and y'''

those are first , second and third derivative

First derivative is

y'=re^{rx}

Second derivative is

y''=r*re^{rx}

y''=r^2e^{rx}

Third derivative is

y'''=r^2*re^{rx}

y'''=r^3e^{rx}

now, we can plug these values into differential equation

and we get

r^3 e^{rx}-9r^2 e^{rx}+20re^{rx}=0

now, we can factor out common terms

e^{rx}(r^3 -9r^2 +20r)=0

we can move that term on right side

(r^3 -9r^2 +20r)=0

now, we can factor out

r(r^2 -9r +20)=0

r(r-5)(r-4)=0

now, we can set them equal

r=0

r-5=0

r=5

r-4=0

r=4

so, we will get

r=0,4,5...............Answer
