Asked by Sammy
Determine the zeros of the function 7x^2 + 9x = 0
answers were:
{-9/7}
{-9/7,0}
{o,9/7}
{9/7}
I think the answer is {-9/7,0} but I'm not positive when I worked it-If this is wrong please steer me into the correct calcs because then I don't what I'm doing wrong
2.Solution to absolute value(x-5) <= 3 is x<=8>=2
This would be true according to my calcs Thanks for checking in advance
