Specify, what are you needing?
Answer:
B
Step-by-step explanation:
I know this because 12 dividend by 13 is closer than 9 than any other answer.
Answer:
x=2 y=-5
Step-by-step explanation:
7x-y=19
2x-3y=19
Multiply the first equation by -3
-3(7x-y)=19*-3
-21x +3y =-57
Add this to the second equation to eliminate y
-21x +3y =-57
2x-3y=19
-----------------------
-19x = -38
Divide by -19
-19x/-19 = -38/-19
x = 2
Now we need to find y
7x-y = 19
7(2) -y =19
14 -y =19
Subtract 14 from each side
14-14 -y=19-14
-y=5
Multiply by -1
y = -5
Let's factor the following polynomial to find the roots:
x2-13x + q = 0
Factoring we have:
(x-12.5) * (x + a)
Where,
-12.5 + a = -13
a = -13 + 12.5
a = -0.5
We now look for the coefficient q:
q = -12.5 * a
q = -12.5 * (- 0.5)
q = 6.25
The polynomial will then be:
x2-13x + 6.25 = 0
Its roots are:
x1 = 12.5
x2 = 0.5
Answer:
The other root and the value of the coefficient are:
0.5 and 6.25 (Respectively)
