The slope-intercept equation is y=mx+b.

The slope formula is $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

Our three points are (5,5), (-5,-7) and (0,-1)

Using our slope formula our slope becomes $\frac{-7-5}{-5-5} =\frac{12}{10} =\frac{6}{5}$

Then, if we use one of our points (pick whichever you want, although (0,1) is the easiest) to solve the equation. So, $y=\frac{6}{5}x-1$ . When we solve for x and y, we get -1=0+b, or b=-1.

When we plug that back into the equation, we get $y=\frac{6}{5}x-1$ .

WHAT IS 5/9-5/18?!PLS HELP ME!!!!

IgorLugansk [536]

Answer:

5/18

Step-by-step explanation:

note: 5/9 is the same as 10/18 (we get this by multiplying both numerator and denominator by 2)

hence

5/9-5/18

= 10/18 - 5/18

= (10-5) / 18

= 5/18

If ex + e*-1= 2, then x =..

lianna [129]

<em>Note: Your equation seems a little unclear. But, I am assuming that your equation is:</em>

$e^x\:+\:e^{-1}=\:2$

<em>Because my solution would still clear your concept about this topic, no matter what the question is.</em>

Answer:

Please check the explanation.

Step-by-step explanation:

Given the equation

$e^x\:+\:e^{-1}=\:2$

subtract $e^{-1}$ from both sides

$e^x+e^{-1}-e^{-1}=2-e^{-1}$

$e^x=2-\frac{1}{e}$

$\ln \left(e^x\right)\:=\ln \:\left(2-\frac{1}{e}\right)$

$\:x\cdot ln\left(e\right)=\ln \:\:\left(2-\frac{1}{e}\right)$

$\:x\cdot 1=\ln \:\left(2-\frac{1}{e}\right)$ ∵ $\:\:\ln \left(e\right)=1$

$x=\ln \:\left(2-\frac{1}{e}\right)$

$x=0.5$

What is the 7th term in the geometric sequence described by this explicit formula?an = –3 • (3)(n – 1)

I am Lyosha [343]

Answer:

7th term = -2187

Step-by-step explanation:

The formula for nth term of a geometric sequence is given by:

$a_n=a*r^{n-1}$

Where

a is the first term,
r is the common ratio,
n is the nth term (term number)

Since the question gives us the formula and wants to know 7th term, we just plug in 7 into n:

$a_n=(-3)*(3)^{n-1}\\a_n=(-3)*(3)^{7-1}\\a_n=(-3)*(3)^6\\a_n=-2187$
