First, distribute -2 to all terms within the parenthesis
-2(2x) = -4x
-2(3) = -6
-4x - 6 + 11 = 11 - 3x
SImplify. Combine like terms
-4x (-6 + 11) = 11 - 3x
-4x + 5 = 11 - 3x
Isolate the x. Add 3x to both sides, and subtract 5 from both sides
-4x (+3x) + 5 (-5) = 11 (-5) - 3x (+ 3x)
-4x + 3x = 11 - 5
Simplify
-x = 6
Isolate the x. Divide -1 from both sides
-x/-1 = 6/-1
x = -6
-6 is your answer
hope this helps
Answer:
0.125
Step-by-step explanation:
Since R is the midmoint of QS that means that QR and RS are equal to each other. So first you need to find x. There are many different ways to set up the equation to solve for x, but I'll show you the easiest one:
QR+QS=RT+QR
(2x-4)+(2x-4)=(8x-43)+(2x-4)
Combine like terms:
4x-8=10x-47
Isolate Variable:
4x-8=10x-47
-4x -4x
6x-47=-8
Isolate Constant:
6x-47=-8
+47 +47
6x=39
Divide:
x=6.5
Check Your Answer:
(Plug in 6.5 as x)
(4(6.5)-8)=(8(6.5)-43)+(2(6.5)-4)
18=18
Answer:
Lol i got u homie!
-0.02
(Sorry if that wasn't a fraction but hopefully this helps)
Step-by-step explanation:
For 1. If two lines are parallel, the slopes are the same.
If two lines are perpendicular, the slopes are the opposite reciprocal, or is -1.
2. The answer is 3/2. Because in a perpendicular slope of a line, it has to be opposite sign and the reciprocal.
3.It is parallel.
because first we solve 6x-3y=8
We move the 6x to the other side, making it -6x
Now we have -3y=-6x+8
We use the y=Mx+b
-3y=-6x+8
Then we divide by -3
answer: y= 2x-8/3
now compare
y=2x+3
and
y=2x-8/3
With this we know it’s parallel because it’s the same slope but different y-intercept .
