Answer:
The system of equations has a one unique solution
Step-by-step explanation:
To quickly determine the number of solutions of a linear system of equations, we need to express each of the equations in slope-intercept form, so we can compare their slopes, and decide:
1) if they intersect at a unique point (when the slopes are different) thus giving a one solution, or
2) if the slopes have the exact same value giving parallel lines (with no intersections, and the y-intercept is different so there is no solution), or
3) if there is an infinite number of solutions (both lines are exactly the same, that is same slope and same y-intercept)
So we write them in slope -intercept form:
First equation:
second equation:
So we see that their slopes are different (for the first one slope = -6, and for the second one slope= -3/2) and then the lines must intercept in a one unique point. Therefore the system of equations has a one unique solution.

The stem-and-leaf plot above shows house sale prices over the last week in Tacoma. What was the most expensive house sold? Give your answer in dollars
Answer:
$370,000
Step-by-step explanation:
Given the stem and leaf plot :
Stem__Leaf
0_____667778999
1_____ 02447778889999
2_____0011234445667889
3_____00011227
The stem is represented in units of hundred thousand and the leaf in ten thousand. Therefore from the plot above, the most expensive house will be the one with both the highest hundred thousand and ten thousand placed value.
300,000(stem) + 70,000(leaf) = 370,000
