How to turn it from standard form to slope intercept form

Answers

7 . X + 2y = 4 (move x beside 4, since it's positive it will be negative)

2y = 4 - X (divide terms to 2)

| 2y ÷ 2 = y | 4 ÷ 2 = 2 | -X ÷ 2 = -1/2 (There's always an imaginary 1 beside x, only just x).

y = 2 - 1/2x (rearrange terms)

y = -1/2x + 2

9. -2x + 3y = -6 (move -2x beside -6, since it's negative it will turn into a positive)

3y = -6 + 2x (divide by 3)

y = -2 + 2/3x (rearrange)

y = 2/3x -2

11. 5x - 2y = 14

-2y = 14 - 5x (-2 ÷ -5x is 5/2x, but since numerator and denominator are negative, fraction turns positive)

y = -7 + 5/2x

y= 5/2x - 7

13. 4x + 3y = 12

3y = 12- 4x

y = 4 -4/3x

y = -4/3x + 4

15. x + 3y = -3

3y = -3 -x

y = -1 -1/3x

y -1/3x - 1

There you go!

Just remember those steps and you should be fine :)

Which statement about the slope of the line is true?The slope from point O to point A is fraction 1 over 4 times the slope of the line from point A to point B.
The slope from point O to point A is 4 times the slope of the line from point A to point B.
It is 4 throughout the line.
It is fraction 1 over 4 throughout the line.

Answers

A straight line has the same gradient all along its length. The gradient equals vertical rise over horizontal distance. It does not matter which triangle you use.
For large triangle it equals 2/8 or 1/4 for smaller one.  Both equal 1/4 (last statement)

What is the approximate volume of the sphere? Use 3.14 to approximate pi and round the answer to two decimal places if needed. A. 48 cm3

B. 150.72 cm3

C. 288.00 cm3

D. 904.32 cm3

Answers

There should have been an image that accompanied this word problem. 
I saw the image of the sphere. It has a radius of 6 cm.

We need the radius of the sphere to solve for its volume.

Volume of a sphere = 4/3 π r³
V = 4/3 * 3.14 * (6m)³
V = 1.33 * 3.14 * 216cm³
V = 902.06 cm³

I solved the problem using the full value of pi and the given answer was Choice D. 904.32

There is a difference in the actual answers because of the use of numbers with that only extends two decimal places.
