How to solve this equation
1) 2(x – 10) + 8x = 10

Answers

Answer 1

Answer:

x = 3

Step-by-step explanation:

First you need to distribute 2(x-10) to make the equation 2x - 20 + 8x = 10

Then add 20 to itself and 10 so the equation becomes 2x + 8x = 30

Now u can just add 2x + 8x which makes the equation 10x = 30

So now you divide 10 by itself and 30. Since that 10/10 cancels out the answer will be 3. There for x = 3

What is the slope of the line that passes through the points (2, –3) and (–2, 5)? 2 1/2 -1/2 -2

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

What is the equation of a line that passes through the point (-1, 3) and is parallel to y=2x -7

Answers

So because it’s parallel you’re gonna have the same slope. You need to use point slope formula to find the equation of the line

y-y1=m(x-x1). Here, x1= -1 and y1=3. Your m is the slope which is parallel which means you’re gonna have the same slope. Our equation is given in y=mx+b form so our m is 2 so the parallel slope is 2. So m=2, x1=-1, y1=3

Plugging all of these in you have

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

Simplifying we have

y-3=2(x+1)

Applying distributive property we have

y-3=2x+2

adding 3 to each side we get

y=2x+5
