Answer:

y=7

Step-by-step explanation:

Parallel lines have the same slope(m) value.

Since our line is parallel to one whose equation is y=4;

The slope of our line is hence zero.

Slope(m) = change in y ÷ change in x

0 = $\frac{y - 7}{x - 0}$

Cross multiplying gives that the equation of our line is;

y=7

Answer:dy/dt(x=3)=54

Step-by-step explanation:

We know that we can write:

$\frac{dy}{dt}=\frac{dy}{dx} *\frac{dx}{dt}$

and so evaluate it as a product of functions, that is for a given value of x or t, we get that

$\frac{dy}{dt}(s)=\frac{dy}{dx} (s) * \frac{dx}{dt}(s)$ .

Now we are told that:

$1. x=x(t),\ 2.y=x^3+4,\ \frac{dx}{dt} =2,\ for \ x=3,$

whenever it happens, this means the influence of t is hidden, and we only consider the result, that is, how much is x when the derivative has the value of 2, we are not concerned for what value of t it happens, since we get all the necessary information beforehand.

Now we need to calculate

$\frac{dy}{dx}=3x^2 \rightarrow \frac{dy}{dx}(3)=3(3)^2=27$ .

Therefore

$\frac{dy}{dt}(x=3)=\frac{dy}{dx} (x=3) * \frac{dx}{dt}(x=3)$ or

$\frac{dy}{dt}(x=3)=27 *2 = 54$ .

The answer was actually posted on another one but it should be step 2; 6x - 12 = 14 + 2x. Or you can search the question again on here and you should find it!
