Problem 1
The portion from t = 0 to t = 5 represents going downhill, which is a total duration of 5 seconds. This is because the speed is going up (the y values are increasing) as you move from right to left for this interval. It looks like you're going uphill here, but keep in mind that the y axis is not position. Instead, the y axis represents speed.
Answer: 5 seconds

Problem 2
You have the correct table. Nice job. Don't forget to show your work if your teacher requires it.

Problem 3
f(x) = x*|-2|^x
f(3) = 3*|-2|^3 ... replace every x with 3
f(3) = 3*(2)^3
f(3) = 3*8
f(3) = 24
The input is x = 3 which leads to the output y = 24
The ordered pair (x,y) = (3,24) is on the function curve
Answer: 24
To determine the total variation in water level, multiply 1.8 mm/year by 2.2 years. The exact answer is 3.96 mm/year. Use rounding to check the answer by using the problem 2(2) =4. 4 is close to 3.96.
Answer:
6x + 3y
Step-by-step explanation:
3(2x + y)
6x + 3y
Bet of Luck!
Huh? I really don’t know what your talking about there isn’t a picture of the problem or something
c. Infinitely many solutions is the right answer
Step-by-step explanation:
Given equations are:
When we closely observe the equations we see that both the equations are equivalent.
From equation 2:
Dividing the equation by 2
We can see that the equation 2 is equivalent to equation 1.
This means that the graph of both equations will be on each other so the equations will have infinite many solutions
Hence,
c. Infinitely many solutions is the right answer
