Combine like terms:
-r-10r
We can always add variables as long as they are the same. So we can not add 10x+20y. That's impossible.
We can't add 3r^2+10r. That's also impossible.
However, we have the same variable, r. So we can add -r-10r. And the answer is:
-11r
Hope this helps! :)
Answer:
x = 1
Step-by-step explanation:
8 -(x+5) = 5x - 3
-(x+5) ---> -1 (x +5) = -x - 5
8 - x - 5 = 5x -3 8 - 5 = 3
-x + 3 = 5x - 3
+x +x
3 = 6x - 3
+3 +3
6 = 6x
/6 /6
<u>x = 1</u>
3k+14=k. Subtract 3k from both sides. 14= -2k. Divide both sides by -2. K=14/(-2)=-7. K is -7.
We would have to use the formula y1 - y2 / x2 - x2.
-5 - 3 = -8
2 - 6 = -4
Now we have -8/-4 and now we simplify to get 2/1
sense the formula of a line is y= mx + b we now how the first part which is
y=2x+b
now we can plug in the plot from the original points to the equation to finsish the problem
3= 2 x 6 + b
6 divided by 2 is 3 and 3 times -3 is -9 so the final answer will be
y=2x-9
