Answer:

(1,-3/4)

Step-by-step explanation:

Luckily, y is already opposites, so it should be easier:

6x-8y=12

5x+8y=-1    

Combine; This should end up with y eliminated -

11x = 11

x = 1

Now we can plug 1 in for x in one of the equations to find y. I'm going to use the second one.

5(1) +8y = -1

5+8y=-1

8y=-6

y=-6/8 (you can simplify)

The point at which the lines intersect is (1,-3/4)

Put the following equation of a line into slope-intercept form, simplifying all fractions.
baherus [9]

Answer: y=-3/2x+3

Step-by-step explanation:

First subtract 3x from both sides to start isolating the y.

Then you get 2y=-3x+6

Divide both sides by 2 to get y alone and you get

y=-3/2x+3

Artyom0805 [142]

Answer:

Points to remember

nCₐ = n!/(r!(n - r)!)

The given word is "FRIENDLY"

F R I E N D L Y is a 8 letter word.

<u>To find the number of combinations</u>

5 letters can be selected from 8 letter = 8C₅

8C₅ = 8!/(8 - 5)!5!

 = 8!/3!5!

 = (8 * 7 * 6* 5!)/(1 * 2 * 3 * 5!)

 = 8 * 7

 =  56

5 letter combinations can be created from the letters in the world “friendly = 56
