Answer:

r (1) = 2; r (n - 1) + 3, for n >_2

and

r (n) = 3n -1

Step-by-step explanation:

yall aint even give us the functions  smh but its only two because r(1) is obv 2 and thats not expressed by any other answers. if u just plug it into the other functions (the ones without the first term) only one of the three work

Well we don't have the choices, maybe they're coming.

We want r(1)=2, r(2)=5, r(3)=8, ...

We can write that

r(n)=2 + 3(n-1)

That's equivalent to

r(n)=3n-1

Hopefully those are the two expressions among the choices.  There are many equivalent expressions but these are the most likely.

Find 7512−(−334) . Write your answer as a mixed number in simplest form.
Savatey [412]

Answer:

7846

Step-by-step explanation:

two 'minus' signs cancel each other out and become an 'plus' sign

therefore

7512-(-334) = 7512 + 334

= 7846

I don't know why you wrote ' write your answer as a 'mixed number ' in 'simplest form'. A mixed number can only be formed when you have a fraction, an improper fraction no less, the answer is a whole number, and therefore cannot be written as a mixed number in simplest form. If I am wrong pls let me know and elaborate by what you mean by 'mixed number' in the comments.

I believe it may be a trick question, but who knows.

Examples of fractions expressed as a mixed number.

19/8 = 2 3/8

17/5 = 3 2/5

10. Evaluate if: y = 4 and z = -2
Bas_tet [7]

Substitute with y = 4 and z = -2

= 4^2*(-2)/4 + 10

= 16*(-2)/4 + 10

= -32/4 + 10

= -8 + 10

= 2

Hope This Helped! Good Luck!
