Answer:
The x-coordinates of the points are x = 3 and x = - 8.
Step-by-step explanation:
We have to find the x-coordinates of the points where the graph of equation y = (x - 3)(x + 8) crosses the x-axis.
Now, the x-intercept of a function implies that y = 0 {Because on x-axis, y-value is zero}
Hence, (x - 3)(x + 8) = 0
⇒ (x - 3) = 0 and (x + 8) = 0
⇒ x = 3 and x = - 8
Therefore, the x-coordinates of the points are x = 3 and x = - 8. (Answer)
Because this is a trick question therefore that is 12 units cubed so its just 12•11
Answer:
267 and 322
Step-by-step explanation:
The number of possible combinations is given by
... C(18, 3) = 18!/(3!(18-3)!) = 18·17·16/(3·2·1) = 816 . . . . possible combinations
_____
There are 18 ways to choose the first one; 17 ways to choose the second one, and 16 ways to choose the 3rd one. The same 3 students can be chosen in any of 3! = 6 different orders, so the product 18·17·16 must be divided by 6 to get the number of possible combinations in which order doesn't matter.
