Question

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

Answer 1

Answer:

$y - 7x = 21$

Step-by-step 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: $y - 7x = 21$
