Answer:
20y - 20
Step-by-step explanation:
We multiply the first term and the second term in the parentheses by the 4. That means we do:
4(5y) + 4(-5)
And we simplify to get:
20y - 20
Answer:
12, 17, 24
Step-by-step explanation:
To find the first 3 terms, substitute n = 1, 2, 3 into the rule, that is
T₁ = 1² + 2(1) + 9 = 1 + 2 + 9 = 12
T₂ = 2² + 2(2) + 9 = 4 + 4 + 9 = 17
T₃ = 3² + 2(3) + 9 = 9 + 6 + 9 = 24
Answer:
Distance between Alan and Alissa (ft/s)
Time (s)
Step-by-step explanation:
In this example, since Alan and Alissa are both traveling at a constant rate, their velocity is not a varying quantity. However, the distance between Alan and Alissa is varying as a function of time at a rate of 9 feet per second. Since the distance is a function of time, time is also a varying quantity.
Therefore, the only varying quantities are the distance between Alan and Alissa (ft/s) and the time (s).
The answer would be 2x^2+2x-4
