Answer:
-8
Step-by-step explanation:
If we let x and y represent the first and second numbers, respectively, we can write the problem statement as the equations ...
We can multiply the first equation by -9 and add 4 times the second equation to get an equation in y alone:
-9(4x +5y) +4(9x +2y) = -9(-28) +4(11)
-37y = 296 . . . . . simplify
296/-37 = y = -8 . . . . . divide by the coefficient of y
The second number is -8.

Answer:
5C
6C
7D
8B
Step-by-step explanation:
5) C because median is the middle of the set of numbers source A median is 4 source B median is 6 and 4 is 2 less than 6.
6) C because there are 6 numbers altogether and 1 6s on a dice so 6+6 because we have two dice and 2 6s on both so 2/12 or simplified 1/6
7) D because mean is all the numbers add up divided by the amount of numbers so 20+25+30+20+30 = 125 and 125 ÷ 5 = 25
8 B because mean is all the numbers add up divided by the amount of numbers so
5+6+7+8+8+8+8+8+8+9+9 = 76 ÷ by 10 is 7.6
7+7+7+7+8+8+8+8+10+10 = 80 ÷ by 10 = 8
8 + 7.6 = 15.6 ÷ 2 = 7.8 and B is closest to 7.8
-6x^4-7x^2+5x-10. hope this helps ! :)
