I'm pretty sure the answer is still 6x-5.
Step-by-step explanation:
Answer:
1/5106
Step-by-step explanation:
Answer:
The solution set is (5,6).
Step-by-step explanation:
Given equations are:
-6x + 6y= 6 Eqn 1
-6x + 3y=-12 Eqn 2
Subtracting Eqn 2 from Eqn 1
(-6x+6y)-(-6x+3y)= 6-(-12)
-6x+6y+6x-3y=6+12
3y = 18
Dividing both sides by 3

Putting y=6 in Eqn 1
-6x+6(6)=6
-6x+36=6
-6x=6-36
-6x=-30

Hence,
The solution set is (5,6).
Y = |x - 1|
and
y = 3x + 2
Equating the values of y, we can write:
|x - 1| = 3x + 2
This means:
A) x - 1 = 3x + 2
x - 3x = 2 + 1
-2x = 3
⇒ x = -3/2 = -1.5
B) - ( x - 1) = 3x + 2
3x + x = 1 - 2
4x = -1
⇒ x= -1/4 = - 0.25
For x = -0.25
y = 3(-0.25) + 2 = 1.25
x = -1.5 is an extraneous root and is not applicable.
So the solution set is (-0.25, 1.25)
Option A gives the approximate solution set.
