Iasked this question this morning, but no combine like terms to create an equivalent expression. 1/7-3(3/7n-2/7) /'s equal fractions

1/7-9/7n+6/7

1-9/7n

That is the extended form and is simplified

Hope it helps! :)

distribute: 1/7 - 9/7n + 6/7

combine like-terms: 1/7 + 6/7 = 1

1 - 9/7n

i think the amount would be $140.62

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
