If y = 3ax - 16 is the equation of the tangent of f(x)= 5x^3 - 3x + c at x = 1, then calculate the value of a .

Substitute the given value into the function and evaluate.

fy=3ax−16=5x3y−3xy+cyfy=3ax-16=5x3y-3xy+cy

x=1=5x3y−3xy+cyx=1=5x3y-3xy+cy

a=5x3y−3xy+cy

Hope this helps, If it did, then I would really appreciate it if you gave me Brainliest, I only need one more to rank up and it has taken forever to get to where I am currently. Thanks.

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
