Answers

Answer: The slope is  -2.

Step-by-step explanation:

(2,-3)

(-2,5)

Using the two given points,  you can find the slope by finding the difference in the y coordinates and diving it by the difference in the x coordinates.

y coordinates:  -3 - 5= -8

x coordinates;  2-(-2) = 4  

Slope:  -8/ 4 = -2

Three more than twice a number x is 15. Determine the value of x.

Answers

Answer:

Pretty sure the answer would be x=6

Step-by-step explanation:

The number (x) in: "3 more than twice a number is 15" is what we are solving here.

In other words, you are looking for a number (x) that if you multiply it by two (same as twice) and then add 3, you get 15.

To solve this, you first write the problem as an algebra equation as follows: 2x + 3 = 15

Then you solve the equation by subtracting 3 from both sides, and then divide both sides by 2. Here is the math to illustrate better:

2x + 3 = 15

2x + 3 - 3 = 15 - 3

2x = 12

2x/2 = 12/2

x = 6

1/2x + 1/4=3/5 solve for x

-1=3x-2

add 2 to both sides

-1+2=3x-2+2

1=3x

divide both sides by 3

1÷3=3x÷3

1/3=x

-3x=9

divide both sides by -3

-3x÷-3=9÷-3

x=-3

-10=-5x

divide both sides by -5

-10÷-5=-5x÷-5

2=x

What is the solution to this system of linear equations?
2x + y = 1
3x – y = –6

(–1, 3)

(1, –1)

(2, 3)

(5, 0)

Answers

x = -1

y = 3

2x + y = 1 (eq no 1)

3x - y = -6 (eq no 2)

solve eq no 1

y = 1 - 2x (eq no 3)

enter eq no 3 into eq no 2

3x - ( 1 - 2x ) = -6

3x - 1 + 2x = -6

5x = -5

x = -5/5

x = -1

enter x = -1 into eq no 1

2 (-1) + y = 1

-2 + y = 1

y = 3

Answer:

A. (-1,3)
