X should be 7 after doing all the calculation.
Answer:
18x^2 - 9
Step-by-step explanation:
y = f(x)= 6x^3 - 9x + 4
dy/dx = d/dx(6x^3) - d/dx(9x) + d/dx (4)
=6.d/dx(x^3) - 9.d/dx (x) + d/dx. (4)
=6.3x^2 - 9.1 + 0 =18x^2 - 9

Answer:
Step-by-step explanation:
Sakal and Roy each have a sack of 50 apples.
All apples are either red or green.
Sakal = x
Roy = y
If Sakal has three times as many red apples as Roy does
x = 3y
and half as many green apples as Roy does,
x = 1/2y
how many red apples does Sakal have?
