Take into account that in general, a linear function can be written as follow:
where m is the slope of the line and b the y-coordinate of the y-intercept.
In this case, you have that m=1/5 and b=-3, then, the line equation is:
In order to graph the line, proceed as follow:
Use two values of x to replace into the equation for y, for instance, use 0 and 5:
The previous results mean that (0,-3) and (5,-2) are two points on the line.
Place the previous points on the coordinate system, and draw a straight line which crosses these points:
The red line is the graph of the given function.
Answer:
x^2+4x
Step-by-step explanation:
Use the Foil formula
s = standard version amount
h = high quality version amount
we know that there were 1090 downloads of the song, meaning s + h = 1090.
we also know that the total amount of MBs downloaded was 3353 MBs, and since the standard is 2.1 MBs and the high quality is 4.9MBs, then 2.1s + 4.9h = 3353.
109 numbers hope this helps :)
