Answer:
The last table given See attached image)
Step-by-step explanation:
Notice that they are asking for the inverse function to the one with the detailed relationship given. The original relationship was assigning to the Domain of number of people attending, the Range of values for charges.
Therefore, the inverse function will be assigning in the opposite way: from the average charges (now the Domain of this relationship), to the number of people attending (now the Range of this relationship). The relationship should also maintain the original element to element connection:
What was:
(20, $10) should now be ($10, 20)
(26, $6.25) should now be ($6.25, 26)
(35, $4) should now be ($4, 35)
This is exactly represented by the last table (see also image attached)
Answer:

Step-by-step explanation:
Using quadratic formula

we will have two solutions.
2x^2 - x - 4 = 0
So, a=2 b=-1 c=-4, we have:

Finally, we have two solutions:

Answer:
open circle on 75.5, arrow pointing right
Step-by-step explanation:
its math
10 000 samples wiegh 1 pound.
1 sample would weigh (1 / 10 000) pound
10 samples would then weigh 1 / 10 000 * 10 = 1/1000 = 0.001 Pound
Answer: 10
Step-by-step explanation:
2x+46+3x-6=90 degrees
5x+40=90 degrees
5x = 50 degrees
x = 10 or 10 degrees
