Could anyone me with this? ? in advance : )

Suppose that f(0) = −3 and f '(x) ≤ 8 for all values of x. how large can f(4) possibly be? solution we are given that f is differentiable (and therefore continuous) everywhere. in particular, we can apply the mean value theorem on the interval [0, 4] . there exists a number c such that

What is the value of x in the equation7x+2y=48 when y=3

Yvaries directly as x. y =90 when x=6. find y when x=13
