Solve the system using multiplication for the linear combination method.6x – 3y = 3
–2x + 6y = 14
What is the solution to the system?
(2, 1)
(2, –3)
(2, –1)
(2, 3)

Answers

Answer 1
Answer: If you would like to solve the system of equations, you can calculate this using the following steps:

6x – 3y = 3
–2x + 6y = 14     /*3
_________
6x – 3y = 3
–6x + 18y = 42
_________
-3y + 18y = 3 + 42
15y = 45
y = 45/15
y = 3

6x – 3y = 3
6x - 3 * 3 = 3
6x = 3 + 9
6x = 12
x = 12/6
x = 2

(x, y) = (2, 3)

The correct result would be (2, 3).

Answer: -2x

Step-by-step explanation: Very easy maths. Just add 4x + -6x, which is -2x. There's your answer.
since both of the X is to the power of one. You can act as if they’re imaginary. do 4 - 6 which equals -2. then your answer would be -2x.

1 you type 500 words in 250 minutes find the wpm2. bus holds 32 students 192 students to use the bus. find the number of students per bus.


Could you please answer and explain? I haven't learned this yet.

Answers

1. wpm = number of words / number of minutes
    so 500/250 = 2wpm

2. if one bus can hold 32 students, and you have 192 of them, divide the amount of students by the number that can fit on one bus
   192/32 = 6 buses

Round all the way 2689

Answers

2689

rounded to the nearest tens = 2690
rounded to the nearest hundreds = 2700
rounded to the nearest thousands = 3000

If the number before the place it needs to be round off is 5 and above, then it is rounded up. If the number is 4 and below, it is rounded down.

For example: 
2444 

rounded to the nearest tens = 2440
rounded to the nearest hundreds = 2400
rounded to the nearest thousands = 2000

What is the slope of the graph of 12x + 3y = –17?A.-4


B.negative one-fourth


C.one-fourth


D.4

Answers

To get the slope you need to solve for y:
12x+3y=-17
Subtract 12x from both sides:
3y=-12x-17
Divide everything by 3:
y=-4x-17/3
The slope is -4.
