1/5x+3/10=-4
1x/5+3/10=-4
1x/5+3/10=-4
x/5+3/10=-4
x=43/2
Answer:
The correct answer is B.
Step-by-step explanation:
In order to find this, calculate out the discriminant for each of the following equations. If the discriminant is a perfect square, then it can be factored.
Discriminant = b^2 - 4ac
The only of the equations that does not yield a perfect square is B. The work for it is done below for you.
Discriminant = b^2 - 4ac
Discriminant = 7^2 - 4(2)(-5)
Discriminant = 49 + 40
Discriminant = 89
Since 89 is not a perfect square, we cannot factor this.

Step-by-step explanation:
Answer:
No solution.
Step-by-step explanation:
1-2k+5k<u><</u>-4+3k Combine like terms on each side wherever you can.
1+3k<u><</u>-4+3k Subtract -3k on both sides (it's less confusing when you get
<u>-3k -3k</u> rid of the variable first).
1<u><</u>-4 1 is not less than or equal to -4, so there is no solution.
I hope this helped you out!! Have a great day (*^3^)╭
