The amount of Diego earns at his part time job is proportional to the number of hours he works. Earns $10 per hour. b. Is y a function of x? Explain how you know?

c. Write an equation describing x as a function y. (Hint: rearrange your equation to solve for x)

b. yes because you can not find y without the x factor because it is independent.

c. f(x)=10x+0

Step-by-step explanation:

since x is time and y is rate of change the equation would be y=10x+0

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
