Which value is a solution of the equation 2 - 8x = -6?<br> A. 1<br> B. 1/2<br> C. -1<br> D. 8

Nuetrik [128]

Answer:

A.) 1

Step-by-step explanation:

First change the equation to 2 + ( - 8x ) = -6 so it’s easier to read

Take away 2 from both sides

So now you have -8x = -8

Divide both sides by -8 so you get positive x and 1

x = 1

Determine if the function f(x) = 4√x − 3x satisfies the Mean Value Theorem on [4, 49]. If so, find all numbers c on the interval

Vedmedyk [2.9K]

Answer:

Step-by-step explanation:

The mean value theorem states that for a continuous and differentiable function on a interval there exists a number c from that interval, that

$f'(c)=(f(b)-f(a))/(b-a)$

First we must determine the endpoints:

$f(49)=-119$

$f(4)=-4$

We find the derivative of the function, f'(c)

$f'(c)=3+2\sqrt{c}$

Therefore:

$3+2\sqrt{c}=((-119)-(-4))/((49)-(4))$

Simplify:

$3+2\sqrt{c}=-23/9$

$c=81/4$
