The correct answer is a. for very high x-values, f(x) moves towards positive infinity.
This can always be determined by two factors.
1) is it linear or something else?
2) Is the lead coefficient positive or negative.
In this case, since the x is not being raised to a power or is not raised to a power itself, we know that there are no asymptotes. That takes care of #1 for us.
As for #2, since the coefficient of x (which is the highest power here) is positive, that means it continues to get bigger. If it were negative it would be the opposite. So, the correct answer is that as x gets bigger, f(x) moves towards positive infinity.
Find the unit rate for miles by dividing the time by the miles.
50 / 2.5 = 20
So it takes 20 minutes for her to walk 1 mile.
Answer: y = -2/5x + 3
Step-by-step explanation:
The formula for a line is: y = mx + b.
<em>m</em> is the slope of the line. We calculate this by looking at how many units the line travels vertically over how many units the line travels horizontally, or rise over run. In this example, we can see that the line goes down 2 units for every 5 it goes to the right, meaning the slope is equal to -2/5.
<em>b</em> is the y-intercept, or where the line crosses the y-axis. In this example, the line crosses the y-axis at (0, 3) making the <em>b</em> value equal to 3.
Therefore, the equation for this line put together is y = -2/5x + 3.
IT SHOULD KEEP THE SAME PROPORTION AS 1/10.
For each dollar earned one tenth is saved or 1/10 and for the $52,000, the saved money is 52000/10 = $5,200
