-8x^3-2x^2-24x-3 I think.
Answer:
<em>Correct choice: B</em>
Step-by-step explanation:
<u>System of non-linear equations</u>
It's given the following system of equations:
![y=x^2+3x+5](https://tex.z-dn.net/?f=y%3Dx%5E2%2B3x%2B5)
![y=x+13](https://tex.z-dn.net/?f=y%3Dx%2B13)
We'll use the substitution method. Substituting y from the first equation into the second equation, we have:
![x^2+3x+5=x+13](https://tex.z-dn.net/?f=x%5E2%2B3x%2B5%3Dx%2B13)
Moving all terms to the left side:
![x^2+3x+5-x-13=0](https://tex.z-dn.net/?f=x%5E2%2B3x%2B5-x-13%3D0)
Simplifying:
![x^2+2x-8=0](https://tex.z-dn.net/?f=x%5E2%2B2x-8%3D0)
Factoring:
![(x+4)(x-2)=0](https://tex.z-dn.net/?f=%28x%2B4%29%28x-2%29%3D0)
There are two solutions:
x=-4, x=2
The first solution gives a value for y:
y=-4+13=9
First solution: (-4,9)
The second solution gives a value for y:
y=2+13=15
Second solution: (2,15)
Correct choice: B
Answer: Answer is in the steps
Step-by-step explanation:
If the system of equations have the same slope and same y-intercepts then it means that they have infinitely many solutions.
if the system of equations have the same slope but different y-intercepts it means that they have no solution because they will never intersect but will always form parallel lines.
If the system of equations have different slopes and different y-intercepts or have same y-intercepts and different slopes it means that they have exactly on solution.
3/5 of 42000 is 25200 so the amount of people who did not vote is 16800 because the beginning amount of 42000 subtracted from 25200 gives you the final answer
If that's confusing the answer is 16800 votes didn't pick the winner
Answer:
the awnser is 19,500
Step-by-step explanation:
you multiply 325 × 2=650 then you multiply 30×650=19,500
