-6x+4y=-12 in slope intercept form

2 answers:

7 0

Slope intercept form is y=Mx+b
First add 6x to each side
Then you get 4y=6x-12
Next divide each side by 4 to get y alone.
Then you get y= 6/4x-3.

Answer:

x= 2 /3 y+2

Step-by-step explanation:

Let's solve for x.

−6x+4y=−12

Step 1: Add -4y to both sides.

−6x+4y+−4y=−12+−4y

−6x=−4y−12

Step 2: Divide both sides by -6.

−6x /−6 = −4y−12 /−6 x= 2 /3 y

=x= 2 /3 y+2

Find the surface area (in terms of π) of a sphere if its volume is 972 π.

Sholpan [36]

Surface area of sphere is $Surface\,\,Area=324\pi$

Step-by-step explanation:

We need to find the surface area of the sphere while we are given volume of sphere = 972π

The formula used to find surface area is:

$Surface\,\,Area=4\pi r^2$

We need to find radius of sphere

We are given Volume = 972π, using this volume we can find radius of sphere

The formula used to find volume is:

$Volume=\frac{4}{3}\pi r^3$

Putting values and finding r

$972\pi =\frac{4}{3}\pi r^3$

$r^3=\frac{972\pi *3}{4\pi } \\r^3=729$

Taking cube root on both sides

$\sqrt[3]{r^3}=\sqrt[3]{729}\\ r=9$

So, Radius of sphere r=9

Now finding surface area:

$Surface\,\,Area=4\pi r^2$

$Surface\,\,Area=4\pi (9)^2$

$Surface\,\,Area=4\pi 81$

$Surface\,\,Area=324\pi$

So, surface area of sphere is $Surface\,\,Area=324\pi$
