Answer:
Step-by-step explanation:
slope = (y2 - y1) / (x2 - x1)
(-3,-4)....x1 = -3 and y1 = -4
(-2,r)....x2 = -2 and y2 = r
slope = 10
now sub
10 = (r - (-4) / (-2 - (-3)
10 = (r + 4) / (-2 + 3)
10 = (r + 4) / 1.....multiply both sides by 1, eliminating the 1 on the right
10 * 1 = r + 4
10 = r + 4
10 - 4 = r
6 = r <======
Answer:
-10
Step-by-step explanation:
f(n)= f(n-2)+f(n-1)
• Put n = 3
=> f(3) = f(3-2) + f(3-2)
=> f(3) = f(1) + f(2)
=> f(3) = -6 + -4
=> f(3) = -10
<span>You need to add 4.0L water.</span>
So 15.90 is almost $16 so you will round up...
and 18 is almost 20
so that would be 20%of $16
so the best estimate would be around $3-$4
