Hello there! Given the coordinates, we can solve for the slope through the formula:

slope = y2 - y1 over x2 - x1

5 - (-7) = 12

(-1) - 2 = -3

The slope of our line is -12/3. When converting, this gives us -4. Hope this helps!

What's 7/8 as a decimal?<br> a. 7.8<br> b. .875<br> c. 8.7<br> d. .78
OverLord2011 [107]
If you would like to write 7/8 as a decimal, you can do this using the following steps:

7/8 = (125*7)/1000 = 875/1000 = 0.875 = .875

The correct result would be b. .875.

Goshia [24]

Let the  be the time in hours, and  meters of fencing completed. 

We know that After three hours, they have 15 meters of fencing complete, our graph will go from the point (0,0) to the point (3,15). We also know that they decide to take a 2-hour break for lunch and then resume building the fence, so our graph will go from the point (3,15) to the the point (5,15). Finally, After four more hours, they have a fence that is a total of 55 meters long, so the final part of our graph will go from the point (5,15) to the point (9,55)


We can conclude that the graph of t vs y is:

12. Solve the equation 6 - 6x = 5x – 9x - 2.
ycow [4]

Answer:

x=4

Step-by-step explanation:

6 - 6x = 5x – 9x - 2

6+2=5x-9x+6x

8=2x

4=x

What you need to do to be able to solve this is move all of the terms that have no variable and the ones that have the same variable to the other side. Once you have that, you should be able to do 6+2 and solve the side that has variables as if it has no variables. Remember that you have to flip the sign when you are moving all of the numbers. Then when you get to the step where both sides have only one number, that is when you would divide the other number, which in this case is 8, by 2, which is the number correlated with x. And that should get x by itself, and give you the solution.
