Use synthetic division to find the quadratic:
-4 | 6 23 -6 -8
6 -24 4 | 8
—————-
6 -1 -2 | 0 = 6x²-x-2 = (3x+1)(2x-1)
So the other two factors are 3x+1 and 2x-1.
Identify the median for the data of Johnny’s test scores: 92, 96, 97, 83, 92, 58, 93, 88, 77, 48, 65, 80, 71

Answer
The median is 83
Step-by-step explanation:
You must put the scores in order to find median.
48, 58, 65, 71, 77, 80, 83, 88, 92, 92, 93, 96, 97
Then you find the number that is in the exact middle of the list.
In this case the median (middle number) is 83

Answer:
x = 3/2
Step-by-step explanation:
4X + 1/2(4X +6)=12
Distribute
4x+2x+3 = 12
6x +3 = 12
Subtract 3 from each side
6x+3-3 = 12 -3
6x = 9
Divide each side by 6
6x/6 = 9/6
x = 3/2
2nd equation:
8 x-y=10 ⇒ y= 8 x-10
We will switch that in 1st equation:
8 x-10=x²+12 x+30, or:
x² + 4 x +40 = 0, a=1,B=4, c=40
Discriminant : D= b² - 4 ac= 16 - 160 = -144 and because it is negative there are no real solutions.
