Two numbers are called x and y
x + y = 15
3x = y+2
Convert to slope intercept:
y = -x + 15
y = 3x - 2
Answer:
Step-by-step explanation:
Solving the proportion, there would be 3.45 liters in each pitcher, meaning that there would be 24.15 liters of lemonade in 7 pitchers.
The ordered pairs are:
<span>{(1, 80), (2, 240), (3, 720), (4, 2160)}
with
a_1 = 80
a_2 = 240
a_3 = 720
a_4 = 2160
The terms are in a geometric sequence with a common ratio of
240/80 = 720/240 = 2160/720 = 3
The equation is:
a_n = 80 * 3^(n - 1)</span>
