Find the slope of the line that passes through points (3,5) and (8,5)

Katyanochek1 [597]

Answer: m = 0

Step-by-step explanation: To solve this problem, we don't even have to use our slope formula. It's important to understand that when we have the same <em>y</em> coordinate in our first ordered pair and our second ordered pair, this means that the line will be flat or horizontal.

When a line is horizontal, it means the line has a slope of zero.

We use the variable <em>m</em> to represent slope.

So here, we can say that <em>m = 0</em>.

Answer:

Option: C is correct.

$x=\ln\sqrt{\dfrac{t+1}{1-t}}$

Step-by-step explanation:

We are asked to solve for 'x' such that we are given a equation as:

$\dfrac{e^x-e^{-x}}{e^x+e^{-x}}=t$

This equation could also be written as:

$e^x-e^{-x}=t(e^x+e^{-x})\\\\e^x-e^{-x}=te^x+te^{-x}\\\\e^x-te^x=te^{-x}+e^{-x}\\\\(1-t)e^x=(t+1)e^{-x}\\\\e^{2x}=\dfrac{t+1}{1-t}$

on taking logarithmic function on both the sides we have:

$2x=\ln (\dfrac{t+1}{1-t})$

(since $\ln (e^x)=x$ )

$x=\dfrac{1}{2}\times \ln (\dfrac{t+1}{1-t})$

as we know $\dfrac{1}{2}\times \ln b = \ln (b^\frac{1}{2})$

Hence, we have: $x=\ln\sqrt{\dfrac{t+1}{1-t}}$

Hence, option C is correct.

Solve the system<br> 4x + 2y = 10<br> x = y + 13

Maslowich

Answer:

$x = 6$

$y = -7$

Step-by-step explanation:

We have the system of equations:

$4x+2y=10\\x=y+13$

Let's solve by substituting. We know that $x=y+13$ , so we can substitute $y+13$ in as $x$ in the equation $4x+2y=10$ .

$4(y+13) + 2y = 10$

Simplify this down so that we have $y$ on one side of the equation:

$4y + 52 + 2y = 10\\\\6y + 52 = 10\\\\6y = -42\\\\y = -7$

Now that we know the value of $y$ , we can substitute it in to the equation $x = y+13$ to find $x$ .

$x = -7+13\\\\x = 6$

Hope this helped!
