Answer:
x=3/22 ; y=-9/44
Step-by-step explanation:
1/2x+1/3=4
=>1/2x=4-1/3
=>1/2x=(12-1)/3
=>1/2x=11/3
=>22x=3
=>x=3/22....(1)
then,
3x+2y
2y=-3 . (3/22)
y=-9/44
Answer:
(-3, 4) is a solution
Step-by-step explanation:
The point (-3, 4) is inside the shaded area of the graph, so is a solution.
You can check in the inequality
y > -2x -3
4 > -2(-3) -3 . . . . substitute for x and y
4 > 3 . . . . . . . true; the given point is a solution

Answer:
10.62
Step-by-step explanation:
Mean can be described as the average of a sum of numbers, it can be calculated by sum ing all the numbers together and then diving by the total
The mean of the set of numbers shown in the question above can be calculated as follows
3+4+6+7+10+15+19+21/8
= 85/8
= 10.62
Hence the mean is 10.62
