Looks good! You have the right answers.
However, the graph for 12 and 15 is inaccurate! Because he starts from a stop sign/stop light, the graph's speed should start from the origin!
Not to confuse you or anything, but this means the graph does not follow the description of the problem. Please let your teacher know so s/he can fix the worksheet.
Answer:
B
Step-by-step explanation:
11 13 18 19 22 25 29 32 37 37 38
find the median (25)
with 11,13,18,19,22 find the middle for that (18) Q1
with 29,32,37,37,38 find the middle for that (37)Q3
Q3-Q1
37-18=19
I believe the solution is x=
.
I hope this helped you out!
I believe its the second one.......the last one is eliminated based on the y intercept......
plug the x and y into the equations and see which side equals.....
Answer:
Step-by-step explanation:
y = 3*x + 4
y = 3*x - 7
Each one of the above equations is the equation for a straight line.
The solution for such a system is the point P ( x₀ , y₀ ) which coordinates belong to both straight lines. According to this, there is only one solution for that system ( only one point of intersection). The intersection of a pair of straight lines either can occur or not depending on the slope of the lines, if they have the same slope they are parallel, then they did not touch each other ever. How can m, be identified in the straight line equation??, just by looking at the coefficient of x.
The two equations have slope 3 they are parallel then there is not a solution ( there is not a common point to both equations)
