What is the solution to the system of equations?
3x - 2y = 8
6x - 4y = 12
Use any algebraic method (substitution or elimination) to justify that the given system of equations has no solution.
What do you know about the two lines in this system of equations graphically?

Answer:
[tex]\displaystyle Inconsistency\:[No\:Solution][/tex]
Step-by-step explanation:
We need to isolate one pair of variables so they are set to zero. Now, in this case, we need to split one of the equations in negative half, so we will select the second equation:
[tex]\displaystyle \left \{ {{3x - 2y = 8} \atop {6x - 4y = 12}} \right. \\ \\ \\ \left \{ {{3x - 2y = 8} \atop {-\frac{1}{2}[6x - 4y = 12]}} \right. \\ \\ \left \{ {{3x - 2y = 8} \atop {-3x + 2y = -6}} \right. \\ \\ \\ \boxed{0 \ne 2}[/tex]
The fact that we have a result like this proves that we cannot obtain a solution from this system, which means that on a graph, these equations are considered parallel [no intersection, so no solution].

p=3829.39
ur welcome
Answer:
p = 10
Step-by-step explanation:
10p - 3 = 2(12 + 4p) - 7
First, distribute within the parenthesis
10p - 3 = 24 + 8p - 7
Combine like terms
10p - 3 = 17 + 8p
Subtract 8p from both sides of the equation
2p - 3 = 17
Add 3 to both sides of the equation
2p = 20
Divide both sides by 2 to get your answer:
p = 10

Let's substitute the given coordinate pair into each inequality:
[tex]y > 2x+6\\-4 > 2(-5)+6\\-4 > -10+6\\-4 > -4\rightarrow\text{Not true!}[/tex]
Since this coordinate pair does not satisfy the inequality (note the coordinate pair must satisfy BOTH inequalities), therefore (-5, -4) is not a solution to this system of inequalities.
Amy, Jane, and Kayla bought tickets to a movie. Amy bought 2 adult tickets and 4 children tickets for $35. 50. Jane bought 3 adult tickets and 3 children tickets for $36. 0. How much will Kayla pay for 5 adult tickets and 4 children tickets?
Answers
Using a system of equations, it is found that Kayla will pay $54.25 for 5 adult tickets and 4 children tickets.
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
Variable x: Cost of an adult ticket.Variable y: Cost of a children ticket.Amy bought 2 adult tickets and 4 children tickets for $35.50, hence:
2x + 4y = 35.50
x + 2y = 17.75
x = 17.75 - 2y
Jane bought 3 adult tickets and 3 children tickets for $36.0, hence:
3x + 3y = 36
x + y = 12
From the first equation:
17.75 - 2y + y = 12
y = 5.75.
x = 17.75 - 2 x 5.75 = 6.25.
Hence the total paid for Kayla is given by:
T = 5 x 6.25 + 4 x 5.75 = $54.25.

if 3x + 28 = 46 what is the value of 2x + 6
Answers
Answer:
18
Step-by-step explanation:
3x + 28 = 46
Subtract 28 from each side
3x + 28 = 46
3x+28-28 = 46-28
3x=18
Divide each side by 3
3x/3 = 18/3
x = 6
Find 2x+6
2(6)+6
12+6

Hey there!
3x + 28 = 46
SUBTRACT 28 to BOTH SIDES
3x + 28 - 28 = 46 - 28
CANCEL out d 28 - 28 because it give you 0
KEEPs 46 - 28 because it help solve for the x-value.
NEW EQUATION: 3x = 46 - 28
SIMPLIFY IT!
3x = 18
DIVIDE 3 to BOTH SIDES
3x/3 = 18/3
CANCEL out: 3/3 because it give you 1
KEEP: 18/3 because it give you the x-value.
NEW EQUATION: x = 18/3
SIMPLIFY IT!
x = 6
Now that we have your x-value we can substitute it into the equation of: 2x + 6
SIMPLIFYING:
2x + 6
= 2(6) + 6
= 12 + 6
= 18
Thus, your answer is: 18
