Answer:

Yes

Step-by-step explanation:

So we substitute the point given x=-5 and y = -3 to see if this solves both equations at the same time so

3(-5) - 9(-3) = 12 ->  -15+27 = 12 -> 12 = 12 [this one works]

8(-5) - 14 (-3) = 2 -> -40 + 42 = 2 -> 2=2 [this one works also]

Since (-5,-3) is a solution to both equations, then this is a solution to this system

Answer: Yes

Step-by-step explanation:

Here

x = -5

y = -3

3x - 9y = 12

Here if you substitute x and y,

3 * (-5) - 9 * (-3)

(-15) - (-27)

=<u>12</u>

8x - 14y = 2

8 * (-5) - 14 * (-3)

(-40) - (-42)

= <u>2</u>

Ten children measured how high they could jump. The results they recorded, in inches, were as follows: 8, 9, 8, 6, 8, 12, 9, 10,
Lorico [155]

Answer:

b) 9 in

Step-by-step explanation:

To find median arrange the data in ascending order and count the number of data's. if the total number of data is odd number, then (n/2)th term is the median.

If the total number of data is even, then Average of (n/2)th term and (n/2)+1 th term is the median

Ascending order:

6, 8, 8 , 8 , 9 , 9 , 10 , 11 , 12 , 16

total = 10. so even number

Median = average of 5th term and 6th term

             =(9+9)/2

             = 18/2

              = 9
