Answer:
There is 5 numbers (not including the sum/25)
The average is add up all the numbers and divide by amount of numbers
25/5=5
The average value is 5
Step-by-step explanation:
14. 2x-1 = 0, x+7=0
x = 1/2, x = -7
15. x^2 + 3x - 10 = 0
(x + 5)(x - 2) = 0
x = -5, x = 2
16. x^2 - 25 = 0
(x-5)(x+5)
x = 5, x = -5
I believe that y=-1.5x-6 is the answer.
