I'm not just going to give you that answer, i'm going to teach you how to do it for yourself. this is a function. what you do first is look at what the question is asking you, it's asking you to solve the function, when the value of x are as follows: -2, 1, 2. start with the easiest number, 1, and plug it in for x in each equation.
5• (1)^2 + 0
10• (1)^2 + 0
then set each equation equal to zero
5 • (1)^2 + 0 = 0
10 • (1)^2 + 0 = 0
now solve each equation. make sure the value value you get for the first equation is a negative number, because the question demands that by giving you "x<1"
complete the same steps for each other value to get the answers. hope this helps.
Hello,

Answer:
234 miles a day
Step-by-step explanation:
<em><u>The whole trip was for 2 weeks (7*2=14 days).</u></em>
<em><u>Since 1 day from each week they took rest, they drove for (14-2(1)=12 days) 12 days.</u></em>
So a total of 2808 for 12 days. The average is 2808 divided by 12 days:
The answer is 234 miles a day
Answer:
$2184
Step-by-step explanation:
The total number of "ratio units" in the ratio fiction : non-fiction is 3+5 = 8. The total number of fiction + non-fiction books is 832, so each ratio units must stand for 832/8 = 104 books.
Then the 3 ratio units of fiction books stand for 3×104 = 312 books. The total spent on fiction books is that number times the average price:
312 × $7 = $2184 . . . . total spent on fiction books
