I believe it is b)
Because you always do rise over the run and if it goes right then it is positive and if it goes left it is negative.
Answer:
x=12
Step-by-step explanation:
16x - (8x + 6) =90
The first step is to distribute the - sign
16x -8x -6 =90
Now we combine the like terms
8x-6 = 90
Add 6 to each side
8x-6+6 = 90+6
8x = 96
Divide each side by 8
8x/8 = 96/8
x =12
Answer:
12/5
Step-by-step explanation:
-3/2 ÷ -5/8 =
-3/2 x 8/-5 =
-24/-10 =
12/5
The answer is A bcs y=mx +c
Answer:
Step-by-step explanation:
E is the midpoint of Ac & D is the midpoint of AB
DE = (1/2)BC {Midpoint theorem}
![x +1 = \dfrac{1}{2}(4x - 6)\\\\\\ Multiply \ the \ whole \ equation \ by 2\\\\ 2*(x+1) =2*\dfrac{1}{2}*(4x - 6)](https://tex.z-dn.net/?f=x%20%2B1%20%3D%20%5Cdfrac%7B1%7D%7B2%7D%284x%20-%206%29%5C%5C%5C%5C%5C%5C%0AMultiply%20%5C%20the%20%5C%20whole%20%5C%20equation%20%5C%20%20by%202%5C%5C%5C%5C%0A2%2A%28x%2B1%29%20%3D2%2A%5Cdfrac%7B1%7D%7B2%7D%2A%284x%20-%206%29)
2*x + 2*1 = 4x - 6
2x + 2 = 4x - 6
Add 6 to both sides
2x + 2 + 6 = 4x
2x + 8 = 4x
Subtract 2x from both sides
8 = 4x - 2x
2x = 8
Divide both sides by 2
x = 8/2
x = 4
