Answer:
There are 14 pairs of Brand A sold.
Step-by-step explanation:
In order to find this, you need to set up a system of equations. You can set up on equation for the number sold:
A + B = 32
And you can set up one for the amount made:
30A + 35B = 1090
Now, in order to solve for the amount of A sold, multiply the first equation by -35 and add the two equations together.
-35A - 35B = -1120
30A + 35B = 1050
----------------------------
-5A = -70
A = 14
Yes
9x^2-12x+4 can be factored to (3x-2)(3x-2). If you use the FOIL method, 3x times 3x gives you 9x^2, 3x times -2 gives you -6x, -2 times 3x gives you -6x (-6x + -6x gives you -12), and lastly -2 times -2 gives you 4.
i believe that c and d are the answers
It looks like we have
and we want to find .
Since is approaching 5, we don't care about the value of when .
We do care about how behaves to either side of . If from below, then , so that
On the other hand, if from above, then , so that
The one-sided limits do not match, since 0 ≠ 8, so the limit does not exist.
