Since it says the line will be parallel to that, keep 2x-3y and replace -6 with a variable.
Like this: 2x-3y=c
Replace x and y with the x and y values from (1,-2)
2(1)-3(-2)=c
Solve for c
2+6=c
8=c
Now, replace c in 2x-3y=c with 8:
2x-3y=8 is the answer
3x+2(x-1)=9x=4
We move all terms to the left:
3x+2(x-1)-(9x)=0
We add all the numbers together, and all the variables
-6x+2(x-1)=0
We multiply parentheses
-6x+2x-2=0
We add all the numbers together, and all the variables
-4x-2=0
We move all terms containing x to the left, all other terms to the right
-4x=2
x=2/-4
x=-1/2
Replace f(x) in the equation with what it equals:
Distribute 4 to each term in parentheses:
The answer is
C.

Step-by-step explanation:
6.5/10 = 0.65 unit price
14/20 = 0.70 unit price
Answer:
Incorrect
Step-by-step explanation:
We are given the equation:
Add both sides by 9.
When we want to tell if the absolute equation has solutions or not, we have to simplify in this form first: or isolate the absolute sign.
If c ≥ 0, the equation has solutions.
If c < 0, the equation does not have solutions.
Therefore, it does not always matter if the constant on right side is in negative because if there is a number on the left side then there is a chance that the equation has solutions.
From |3x+8| = 4 is equivalent |3x+8|-9=-5 and the right side is 4 which is positive.
Hence, the equation does have a solution!
