Subtract the like terms:
6x^2 - 2x^2 = 4x^2
3x - -4x = 3x+4x = 7x
1 - 5 = -4
Now combine them to get the final answer:
4x^2 + 7x - 4
3 1/5 = y - 12/25
Make 3 1/5 an improper fraction.
16/5 = y - 12/25
Add 12/25 to both sides.
16/5 + 12/25 = y
Make a common denominator.
80/25 + 12 / 25 = y
92 / 25 = y
3 17/25 = y
Hope this helps!
D, because of the arrows going both directions, you know part of it,
![( - \infty \: x) \: ( x \: \infty )](https://tex.z-dn.net/?f=%28%20-%20%20%5Cinfty%20%5C%3A%20%20x%29%20%5C%3A%20%28%20x%20%20%5C%3A%20%20%5Cinfty%20%29)
and then you just have to put in the values from the number line. The first arrow ends at zero with a bracket, and brackets mean the number is included. So now you have,
( - infinity, 0] ( x, infinity)
Then, your last value is at 1/2 with a parentheses, indicating it is not included. So, your final answer would be,
( - infinity, 0] ( 1/2 , infinity)
{infinity is always written with a parentheses in domain}
