## Need to find slope x-2/3y=1/4

So, (12x) / 12 - (8y) / 12 = 3 / 12;

Then, 12x - 8y = 3;

8y = 12x - 3;

y = (12x)/8 - 3/8;

y = (3x)/2 - 3/8;

y = (3/2)x - 3/8;

The slope is 3/2.

## Fine the domain of: y = -3x + 1 A. All negative number B. X > 0 C. All real numbers D. X = 3

C all real numbers are the same

## 3 x + 2 y = 20 if x = 3 in the equation above, what is the value of y ?

Y=9!

Hope that's right

## Can anyone help me and show me how to get the answer to this problem 54➗6+2(8-3*4)

## The area of the cross section of a sphere at the largest point is 100π square miles. what is the total surface area of this sphere? leave your answers in terms of π.

The cross-section of a sphere is a circle . The area of a circle can be calculated by the formula A= Where r is the radius of the circle.

Given :

Solving for r we have:

Or r= 10.

The area of a sphere is calculated by the formula :

Substituting r value we have:

SA=

The total surface area of this sphere is 400π .

## Can u show me how to get the answer for this problem 54➗6+2(8-3*4)

first of all the brace and x or / before + or -

3x4=12

8-12=-4 => first part

54/6=9

9+2=11 => second part

11x(-4)=-44

## What is the equation of the line that has a slope of 1/4 and a Y intercept of -3

**Solution: **

we have been asked to find

The equation of the line that has a slope of 1/4 and a Y intercept of -3.

The standard equation of straight line in the slope-intercept form is given by the formula

where m is the slope of the straight line and b is the y-intercept.

Substitute the given values we get

**Hence the equation of the line that has a slope of 1/4 and a Y intercept of -3 is**

## 1. N+5(n-1)=7 2. -4(r+6)=-63 Solve each equation

Hey there! :)

1) n + 5(n - 1) = 7

Simplify.

n + 5n - 5 = 7

Add 5 to both sides,

n + 5n - 5 + 5 = 7 + 5

Simlify.

n + 5n = 12

Simplify.

6n = 12

Divide both sides by 6.

6n ÷ 6 = 12 ÷ 6

Simplify.

**n = 2**

2) -4(r + 6) = -63

Simplify.

-4r - 24 = -63

Add 24 to both sides.

-4r - 24 + 24 = -63 + 24

Simplify.

-4r = -39

Divide both sides by -4.

-4r ÷ -4 = -39 ÷ -4

Simplify.

**r = 39/4**
