Answer:
15
Step-by-step explanation:
6=S
therefore, to find one you must divide both sides by 6
the answer should be = 1=S/6
N; n+1; n+2 - 3 consecutive numbers
n(n + 1) = (n + 2)² - 19 |use a(b + c) = ab + ac and (a + b)² = a² + 2ab + b²
n² + n = n² + 4n + 4 - 19 |subtract n² from both sides
n = 4n - 15 |subtract 4n from both sides
-3n = -15 |divide both sides by (-3)
n = 5
n + 1 = 5 + 1 = 6
n + 2 = 5 + 2 = 7
Answer: 5; 6; 7.
When x = 0 y = a(b)^x = a which is the y intercept
so as the y-intercept = 3 a must be = 3.
