Answer:
c) f(x)=3x+1
Step-by-step explanation:
the graph of this function, g(x), is y=3x-1, we know this because the slope is 3 and the y intercept is -1.
finding slope:
subtract the y values and x values and then divide.
y2-y1/x2-x1=2+1/1-0
=3/1
slope=3
finding the y intercept:
more of a visual task, find where the line intersects on the y axis. in this case, it is at -1
plug it in:
next all you have to do is plug this into slope intercept form (y=mx+b), where m is slope and b is y intercept.
y=3x-1
making f(x) from g(x):
all you have to do is add 2 to the y intercept because the question says f(x) is 2 units above g(x).
y=3x-1+2
<em>y=3x+1</em>

Rachel will have ran 114 miles in six weeks.
There's five weekdays in a week: (3.2 x 5) = 16 miles
There's two days in a weekend: (1.5 x 2) = 3 miles
16 [weekday] + 3 [weekend] = 19 miles [7-day week]
(19 x 6) = 114 miles
Hope this helps, please mark brainliest. Have an amazing rest of your day and stay safe! xx

Use long multiplication to evaluate.
Answer:
standard deviation
Step-by-step explanation:
The standard deviation is defined as the measure of how spread out the numbers are in a given population. In other words, statistics refers to the amount of the dispersion or variation of a set of given values.
It is denoted by the Greek letter sigma, σ.
Thus the standard deviation is the measure of how dispersed the data are in the population which can be used to provide context to a larger data sets.
