Answer:
The value of k is -21
Step-by-step explanation:
ax² + bx + c = 0
Sum of the roots = -b/a
3x² + kx + 1 = 0
= sum of the roots = -k/3
-k/3 = 7
Now, Multiply both side by (-3) we get,
(-3)-k/3 = 7(-3)
k = -21
Thus, The value of k is -21

Step-by-step explanation:
m = -91.3
Since you move from 91.3 to the other side of the equal sign, it becomes a negative number (-91.3)
Think of the equal sign as a seperator from the positive and negative side.
If you also get an equation like -x=91.3, just flip the -x, to x, and change the 91.3 to a negative 91.3!
Cheers!
