Question

A) y=(x+4)7-7)
Convert factored form to standard form

Answer 1

`y - 7x = 21`

Explanation:

Given

`y = (x + 4)7 - 7`

Required

Convert to standard form

`y = (x + 4)7 - 7`

Start by opening the bracket

`y = x*7 + 4*7 - 7`

`y = 7x + 4*7 - 7`

`y = 7x + 28 - 7`

`y = 7x + 21`

Subtract 7x from both sides

`y - 7x = 7x - 7x + 21`

`y - 7x = 21`

Hence:

The standard form is:
`y - 7x = 21`
