How to turn it from standard form to slope intercept form

Answers

Answer 1

Answer:

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 :)

You have six trophies to arrange on the top shelf of the bookcase how many ways are there to arrange the trophies

Answers

Answer:

So, we can do it in 720 ways.

Step-by-step explanation:

We have been given total of six trophies to arrange in the top shelf of the bookcase

If we need to arrange n things in different ways we can do it in n! ways

Similarly, Here we will do it in 6! ways

n!=n(n-1)(n-2).....1

So, 6!=6 x 5 x 4 x 3 x 2 x 1=720
