I graphed this line below.
Start with an open dot on 7.
The reason we use an open dot is because x
does not equal 7, it is only greater than 7.
So from your open dot, draw an arrow to the right
to represent all numbers greater than 7.
Finally, state your answer in set notation if possible.
It is read as {x: x > 7}.
Answer:
Step-by-step explanation:
The funtion is:
C(p)= 3(p)+1.07 (1)
where: 3 is the package cost, p is the number of packages and 1.07 is the taxes
the cost could be equal or less than the gift card value so:
C (2)
Replace 2 en 1
x 1.07
3(p)
14.02\\\\p\leq \frac{14.02}{3} \\\\p\leq 4.67[/tex]
It´s important to aprox the quantity to the minimum value so I can buy 4 packages
The reasonable domain is for all R because any number is a possible value of the independent variable
Answer:
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
The slope can be found from two points.
The two points from the graph are (1, 9) and (2, 12).
Plugging in the values and evaluating.
The slope of the line is 3.
The y-intercept of the line is where the line cross the y-axis.
The line crosses the y-axis at (0, 6).
The slope-intercept form of the line is:
