Answer:

y=3x+b

Step-by-step explanation:

finding slope:

slope= y2-y1/x2-x1

-2--5/3-2

3/1

slope is 3

i'm not sure how to find the y-intercept using this format but hope this kinda helped!

Which equation is the inverse of 2(x - 2)2 = 8(7 + y)?

Scrat [10]

The inverse of an equation is the opposite of the equation

The inverse of the function is $y =2 \pm \sqrt{28 + 4x$

<h3>How to determine the inverse of the function </h3>

The equation is given as:

$2(x - 2)^2 = 8(7 + y)$

Divide both sides of the equation by 2

$(x - 2)^2 = 4(7 + y)$

Open the bracket

$(x - 2)^2 = 28 + 4y$

Take the square roots of both sides

$x - 2 = \pm\sqrt{28 + 4y$

Add 2 to both sides

$x =2 \pm \sqrt{28 + 4y$

Swap the occurrences of x and y

$y =2 \pm \sqrt{28 + 4x$

Hence, the inverse of the function is $y =2 \pm \sqrt{28 + 4x$

Calculate using Cauchys integral formula

zhuklara [117]

Answer:

9πi/2

Step-by-step explanation:

$\oint\limits_C {\frac{5z^{2}+4}{(z-1)(z+3)} } \, dz,\ C: |z|=2$

Let f(z) = (5z² + 4) / (z + 3).

$\oint\limits_C {\frac{f(z)}{z-1} } \, dz,\ C: |z|=2$

Using Cauchy's integral formula:

$2\pi i\ f(1)\\2\pi i\ (\frac{5(1)^{2}+4}{1+3}) \\2\pi i\ (\frac{9}{4}) \\\frac{9\pi i}{2}$

Please help me out !! ( I will mark brainliest)

Question 1: The y-intercept is where the line crosses the y-axis. The increments of the y-axis is by 20, and the y-intercept is at (0, 20).

The slope is the change in y over the change in x. Find two points:

(0, 20) and (2, 80)

Now:

(80 - 20)/(2 - 0) = 60/2 = 30

Slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

So:

y = 30x + 20

Question 2: Again, look for the y-intercept, which is pretty clear. It's (0, 60).

Now find two points:

(0, 60) and (2, 40)

Find the slope:

(40 - 60)/(2 - 0) = -20/2 = -10

So, the equation is:

y = -10x + 60

And, there you go!
