Answer:
y = 3x + 30
Step-by-step explanation:
This is what the table should look like.
Number of Bars Sold (x) Total Earnings (dollars) (y)
0 30
1 33
2 36
3 39
When x = 0, y = 30. The point (0, 30) is the y-intercept.
As x goes up by 1, from 0 to 1, from 1 to 2, from 2 to 3, y goes up by 3, from 30 to 33, from 33 to 36, from 36 to 39.
A change of 1 in x results in a change of 3 in y.
That is a slope of 3 since
slope = (change in y)/(change in x)
The equation of a line in slope-intercept form is
y = mx + b
We have m = 3 and b = 30, so the equation is
y = 3x + 30
Answer: 3x + 30
Answer:
Yes, it is a linear equation. This equation is in y=mx+b form, which is a linear equation. To rearrange it into y=mx+b form, you'll just do y= -2x+8
To make a line, you only need two points, so here are two points that fit into the line of y= -2x+8:
(0,8) and (1,6)
Answer:
Can't be answered.
Step-by-step explanation:
No system of equations nor solid variables to substitute, eliminate, or graph.
Domain is infinite.
First lets convert the diameter to cm,
2.4 m equals 240 cm, that is by multiplying 2.4 times 100 because 1 meter has 100 cm
then we need to know how to calculate the circumference, and that is by multiplying pi (3.14) times the diameter of the circumference, that is:
circumference = pi*diameter = 3.14*240
circumference = 753.6 cm
that is the solution
Do you have a picture of the graphs to choose from? :)
