what is the equation in slope- intercept form of the line that passes through the points (-26 -11) and (39, 34) ?A) y = -9/13 x
Alisiya [41]

what is the equation in slope- intercept form of the line that passes through the points (-26 -11) and (39, 34) ?



A) y = -9/13 x + 7

B) y = -9/13 x - 7

C) y = 9/13 x + 7

D) y = 9/13 x - 7 ​

step 1

Find out the slope

m=(34+11)/(39+26)

m=45/65

simplify

m=9/13

step 2

Find the equation in slope intercept form

y=mx+b

we have

m=9/13

point (39,34)

substitute and solve for b

34=(9/13)(39)+b

b=34-27

b=7

therefore

the equation is

y=(9/13)x+7

Answer:

Isolate the variable by dividing each side by factors that don't contain the variable.

Exact Form:

x=1211x=1211

Decimal Form:

x=1.¯¯¯¯09x=1.09‾

Mixed Number Form:

x=1111

Step-by-step explanation:

Hope this helps, If it did, then I would really appreciate it if you gave me Brainliest, I only need one more to rank up and it has taken forever to get to where I am currently. Thanks.

Lim x→π/2 1-sinx/cot^2x<br>any genious help please ​
Simora [160]

Rewrite the limand as

(1 - sin(<em>x</em>)) / cot²(<em>x</em>) = (1 - sin(<em>x</em>)) / (cos²(<em>x</em>) / sin²(<em>x</em>))

… = ((1 - sin(<em>x</em>)) sin²(<em>x</em>)) / cos²(<em>x</em>)

Recall the Pythagorean identity,

sin²(<em>x</em>) + cos²(<em>x</em>) = 1

Then

(1 - sin(<em>x</em>)) / cot²(<em>x</em>) = ((1 - sin(<em>x</em>)) sin²(<em>x</em>)) / (1 - sin²(<em>x</em>))

Factorize the denominator; it's a difference of squares, so

1 - sin²(<em>x</em>) = (1 - sin(<em>x</em>)) (1 + sin(<em>x</em>))

Cancel the common factor of 1 - sin(<em>x</em>) in the numerator and denominator:

(1 - sin(<em>x</em>)) / cot²(<em>x</em>) = sin²(<em>x</em>) / (1 + sin(<em>x</em>))

Now the limand is continuous at <em>x</em> = <em>π</em>/2, so

\displaystyle\lim_{x\to\frac\pi2}\frac{1-\sin(x)}{\cot^2(x)}=\lim_{x\to\frac\pi2}\frac{\sin^2(x)}{1+\sin(x)}=\frac{\sin^2\left(\frac\pi2\right)}{1+\sin\left(\frac\pi2\right)}=\boxed{\frac12}
