The awnser is 1920,000,000 I hope I helped you the decimal skips eight spaces
Notice that equality holds when either
or
, so these should be included in the solution set.
Now, since the coefficient of the leading term is positive, we know the parabola opens upward, which means we know that
when
and
, and that
when
.
So the solution set is the interval
.
1x=7
1x/1=7/1
x=7

To find the amount that each of the 4 friends paid for the peaches, you should first calculate the total cost of the peaches, then divide by the numer of friends (4).
First, let's calculate the total cost of the peaches.
18.4 pounds × $1.75/pound = $32.20
Now, divide by the number of people who were contributing to the cost of the peaches (there are 4) -
$32.20 ÷ 4 = $8.05
The correct answer is $8.05.
The equation would be 12x+85=y
x= # of people
y= Total amount of money
Edit: I did #4 sorry
