Answer:
Function: 
Not Function: 
and 
Step-by-step explanation:
Given
Required
Determine if 
is a function of 
Solving x+y=9
Make y the subject of formula
<em>Hence; y is a function of x</em>
Solving
Subtract x² from both sides
Square root of both sides
This implies that
or 
<em>Because </em><em> can be any of those two expressions, it is not a function.</em>
Solving
Reorder
Take square roots
This implies that
or 
<em>Because </em><em> can be any of those two expressions, it is not a function.</em>
Cost of 2 pounds of almonds = $ 21.98
So, cost of 1 pound will be = 
Cost of 3 pounds of dried apricots = $26.25
So, cost of 1 pound will be = 
So, comparing the two costs, the cost of 1 pound of dried apricot is less than 1 pound of almonds by $2.24
Since a serving is 1/2 cup and he needs 72 servings you can multiply 72 by 1/2 and find out that he needs to make 36 cups of punch. Two cups is a pint so he needs (36 / 2) 18 pints of juice. He already has the 8 pints of pineapple juice so 18 - 8 leaves 10 pints of orange juice.
Answer:
$475
Step-by-step explanation:
There are 3 possible accident in this question
3% chance of losing $2000
0.1% chance of losing $150,000
96.9% chance of losing $0
Then the expected value that you will lose is:
3%* $2000 + (0.1% * $15000) + (96.9% * $0)= $75
Profit made by subtracting the price with the lose. If the company want average profit $400, the charge should be:
average profit = premium price - average lose
premium price= average profit + average lose
premium price= $400 + $75 = $475
9x= x+4
Subtract x on both sides to balance the equation.
8x= 4
Divide 8 into both sides. (the inverse of multiplication)
x= 1/2
We can check this by plugging in x.
9(.5)= .5+4
4.5= 4.5
I hope this helps!
