How do you put 2x + 3y = 1,470 into function notation

f(x) = - x + 490

Step-by-step explanation:

noting that y = f(x), rearrange making y the subject

2x + 3y = 1470 ( subtract 2x from both sides )

3y = - 2x + 1470 ( divide terms by 3 )

y - - x + 490 , that is

f(x) = - x + 490

your answer is 23/2 - 13.5

step-by-step explanation:

7/2 evaluates to

multiply x and 4.5

multiply x and 1

the x just gets copied along.

the answer is x

x

4.5*x evaluates to 4.5x

multiply 3 and 4.5x

multiply 1 and x

the x just gets copied along.

x

4.5*x*3 evaluates to 13.5x

7/2-4.5*x*3 evaluates to

  + 8 =

the answer is

7/2-4.5*x*3+8 evaluates to

d) 48
