Answer:
y = 14
Step-by-step explanation:

When x = 2:


That's it. :)
-5 is on the left side of zero (negative) and 5 is on the right side of zero (positive). So, 5 is the answer...
Every week he withdraws $35 from the $950 in his savings, and he wants at least $600 by the end of the summer. So we could write:

Where 'x' is the number of weeks. Now let's solve it for 'x'.
Subtract 950 to both sides:

Divide -35 to both sides, don't forget to switch the sign when dividing/multiplying by a negative number:

So he can only withdraw at money for at most 10 weeks if he wants at least $600 left in his account.
12 flips, 11 heads, 1 tails
Let's say there's a 50-50 chance of landing heads.
There are 12 flips and 12 specific outcomes.
The probability is 2^(-12) = 1/4096 = 0.0244%
If the last flip doesn't matter, then the probability would be 2^(-11) = 1/2048 = 0.0488%.
Have an awesome day! :)
