To solve this problem, you just need to add the two functions together, making sure that you watch your signs.

f(x) + g(x) = (2x - 7) + (-6x -3)

After we simplify and combine like terms, we get:

f(x) + g(x) = 2x - 7 - 6x - 3
= -4x - 10

The domain is all real numbers because both of the functions being added together also have a domain of all real numbers.

Therefore, the answer you have selected (the last option) is correct.

Hope this helps!

A point moves along the curve y = √ x in such a way that the y-component of the position of the point is increasing at a rate of

Eduardwww [97]

Answer:

The value of x component changes at a rate of $\frac{dx}{dt}=4\sqrt{x}$ units per second

Step-by-step explanation:

We are given that $y=x^{\frac{1}{2}}$

Differentiating on both sides with respect to time we get

$\frac{dy}{dt}=\frac{d\sqrt{x}}{dt}\\\\\frac{dy}{dt}=\frac{1}{2}x^{\frac{-1}{2}}(\frac{dx}{dt})\\\\\frac{dy}{dt}=\frac{1}{2\sqrt{x}}\frac{dx}{dt}$

It is given that $\frac{dy}{dt}=2units/sec$

Solving for $\frac{dx}{dt}$ we get

$\frac{dx}{dt}=\frac{dy}{dt}\times 2\sqrt{x}\\\\\frac{dx}{dt}=4\sqrt{x}$
