Question

These really confus me....


Solve the following inequality:
-7r + 1 < -62

Answer 1

what would say
-7r + 1 = -62
give you if you solve it for "r"?

Answer 2

r < -9 r < 9
r > -9 r > 9

Answer 3

So in the long run...you want to isolate 'r' right?

so we need to get rid of all the "extra stuff" that is next to your r

-7r + 1 < -62

we want to get rid of that +1.....so lets do the opposite of adding 1...and lets subtract 1 from both sides of the equation (to maintain equality)

-7r + 1 - 1 < -62 - 1

this leaves us with

-7r < -63

Now we want to completely isolate 'r'...so since r is being multiplied by -7...we should divide both sides by -7

****when dividing or multiplying by a negative number SWITCH THE DIRECTION OF THE SIGN***

-7r / -7 < -63/-7

r > ?

Answer 4

Those are my awnsers....
