I think that the correct answer would be <span>6.5 · 10^9. but im not 100% positive
</span>
Yes what do you need help with
4.2*10^-2
..........................
The first one for the first y-intercept number is -1.
The second one is 5. (Not negative)
The third one is 11 (Not negative)
The fourth one is just 11 (Not negative as well)
The ones that say Not negative means that those numbers are postive.
I hope this helps though! :D
I love these problems, because it's just about reading the question. All you need to do is break it down. What do we know the "sum of" something is? We know that it means addition. What are we adding? "three times a number b and 33". Well, how can we express "three times b"? 3b! Right! Well, we know we're adding that to 33, so you're almost done. Right now you should have 3b+33. And what <em>is</em> 3b+33? at least 33. How can we express "at least"? >=, greater than or equal to, right! Finally, we have our answer. 3b+33>=35.
