- Reading a coordinate plane
- Solving systems of equations by graphing
Step-by-step explanation:
If 2 lines are parallel, they will have no solution.
If 2 lines are the same, they will have infinite amount of solutions.
We see from the graph that the 2 lines intersect at one point, near x = 1.5.
∴ our systems has 1 solution.

Answer:
Step-by-step explanation:
We are given the following in the question:
Keith has $100 in a savings account at the beginning of the summer.
Let x be the number of weeks he works.
He makes $25 each week at his babysitting job.
He wants to earn more than $350 dollars during summer.
Total money earned by job = 
His total money in account should be more than 350$.
We can write this with the help of inequality:
The following inequality represents the given situation.
Find the mean and median of the data set 3,5,6,2,10,9,7,5,11,6,4,2,5,4
Tanya [424]
Answer:
mean: 5.6 ; median: 5
Step-by-step explanation:
first order them:
2, 2, 3, 4, 4, 5, 5, 5, 6, 6, 7, 9, 10, 11
now we can see that the median is 5 since it's in the middle
and the mean is adding all and dividing by how many numbers we have (AKA 14) so 2+2+3+4+4+5+5+5+6+6+7+9+10+11 = 79 and now we divide 79 by 14 which is:
5.64285714
