First put these in order from least to greatest.
1,2,2,4,8,9,9 is the correct order
Range is when we subtract the greatest value of our data set from the smallest so in our case it would be 9-1 which leaves us with our answer that 8 is your range.
2

Suggesting that you want this in standard form, in terms of quadratic equations, you would technically follow a process similar if not almost exactly like the 2 - step equation method with the exception of separating the (x)s and the equations to find x and then plug it in and what-not.
With that being said you would subtract 5 in (x+5) from said 5 in the second equation and -10 in the first equation in order to get 2x^2+7x-15, you would continue to do the same for the x by subtracting it from both ends making the 7x a 6x because there is a 1 at the beginning of each x if there is no number that is shown already. Which finally gives you the equation (y= 2x^2+6x-15)
Answer:
Quadrant III
Step-by-step explanation:
Because both numbers are negative, the point lands in Quadrant III.
3 giant Sandwiches,
8 friends,
Have to be shared equally,
Each friend gets =

If we solve, we'll end with 0.375 Which is between 0 and 1.
So,
It will lie in between 0 and 1.

Answer:
...
Step-by-step explanation:
di = 2.5 -( - 1.5) = 4
radius = di/2 = 2
c(x, y) =( - 0.5 , 2.5-0.5) =(-0.5 , 0.5)
