y = A system of equations. y equals StartFraction one-half EndFraction x minus 6. x equals negative 4.x – 6

Let's solve each of the questions one by one.

1. System of equations: \( y = \frac{1}{2}x - 6 \) \( x = -4 \)

   Substitute \( x = -4 \) into the equation for \( y \): \[ y = \frac{1}{2}(-4) - 6 = -2 - 6 = -8 \] Thus, the solution is (-4, -8). But it seems like that option isn't explicitly listed. Please clarify if there's an issue with the specified options.

2. System of equations: \( y = \frac{2}{3}x + 3 \) \( x = -2 \)

   Substitute \( x = -2 \) into the equation for \( y \): \[ y = \frac{2}{3}(-2) + 3 = -\frac{4}{3} + 3 = -\frac{4}{3} + \frac{9}{3} = \frac{5}{3} \] Thus, the solution is (-2, \(\frac{5}{3}\)).

3. Infinitely many solutions: For both equations to represent the same line, they must be equivalent. Starting with the first equation: \( y = -2x + 4 \)

   Rearranging this to a linear form: \( 2x + y = 4 \)

   To find what value can be placed in the box of the second equation \( 6x + 3y = __ \), we can multiply the first rearranged equation by 3: \[ 6x + 3y = 12 \] Therefore, the answer is 12.

4. System of equations: \( y = -3x - 2 \) \( 5x + 2y = 15 \)

   Substitute \( y = -3x - 2 \) into the second equation: \[ 5x + 2(-3x - 2) = 15 \] \[ 5x - 6x - 4 = 15 \] \[ -x - 4 = 15 \] \[ -x = 19 \Rightarrow x = -19 \] Substitute back to find \( y \): \[ y = -3(-19) - 2 = 57 - 2 = 55 \] Thus, the solution is (-19, 55).

5. Conclusion drawn by Lian: Since Lian found that with her substitution she got the equation \( 75 = 75 \), it indicates both gyms have the same monthly rate and the same membership fee. Thus, the conclusion is: Both gyms charge the same monthly rate and the same membership fee.

6. Solution to the system (from tables): To find the intersection point, we look for equal \( y \) values in both tables. The first table has:

   • \( y \) values of 26, 18, 10, 2 The second table has:
   • \( y \) values of 14, 8, 2, -4

   The only common \( y \) value is 2, which occurs at different \( x \) values. From the first, when \( x = 2 \) and from the second at \( x = 0 \). Thus, the solution is (2, 2).

7. Ernesto's first error: In Step 2, when substituting for \( x \) into the second equation, he should have: \[ 3(y + 7) - 2y = 8 \] Which should simplify to: \[ 3y + 21 - 2y = 8 \] He made the first mistake here in Step 3.

8. Solution to the second system (from tables): Analyzing both functions:

   • The first has \( y \) values of -22, -10, 2, 14
   • The second has \( y \) values of -30, -21, -12, -3

   Since they intersect, we can check their values. It appears that the only way to match is to test combinations.

   The second table doesn't provide feasible solutions for \( y = 2 \), so we can check examples to get the proper intersection but it provides no matches; options lead to potential misalignment. Please let me know for further context.

9. Infinitely many solutions for the second equation: Rearranging \( 2y - 4x = ___ \) to find commonality gives a clue about what would round out into parallel equivalences: Solve: \[ 2y = 2x - 5 \] Yields –10.

10. Solution to the system: Solve two equations: \[ y = 1.5x - 4 \] \[ y = -x \] Set equal to each other: \[ 1.5x - 4 = -x \] Rearranging gives \[ 2.5x = 4 \Rightarrow x = 1.6 \] Substituting back gives: \[ y = -1.6 \] Thus, the solution is (1.6, -1.6).

[-13/3, -25]
[-14/3, -54]
(-13, -50)
(-14, -54)

Let's reassess both questions one at a time using the provided options.

6. First System of Tables

The two tables are as follows:

Table 1:

• \( x: -4, -2, 0, 2 \)
• \( y: 26, 18, 10, 2 \)

Table 2:

• \( x: -4, -2, 0, 2 \)
• \( y: 14, 8, 2, -4 \)

To find the solution to this system of functions, we look at the specific points where the \( y \) values are equal.

From both tables:

• At \( x = 2 \):

  • Table 1: \( y = 2 \)
  • Table 2: \( y = -4 \) (no match)

• At \( x = 0 \):

  • Table 1: \( y = 10 \)
  • Table 2: \( y = -12 \) (no match)

• At \( x = -2 \):

  • Table 1: \( y = 18 \)
  • Table 2: \( y = 8 \) (no match)

• At \( x = -4 \):

  • Table 1: \( y = 26 \)
  • Table 2: \( y = 14 \) (no match)

• The only pair that gives a match is:

  • Both tables have \( y = 2 \) at \( x = 0 \) (which would be a likely intersection, not provided as a direct choice).

Since the provided option isn't listed, it looks like no valid set from the tables can meet that intersection in specified form.

However, looking at the options given, none of them apply to coordinate matches derived from the charts, but since we need a choice, my evaluation finds no clear invalid point,

Let’s agree on checking if “(1, 0)” is representative of vague behavior from varied findings or expectations represented from their linearity.

8. Second System of Tables:

Table 1:

• \( x: -6, -3, 0, 3 \)
• \( y: -22, -10, 2, 14 \)

Table 2:

• \( x: -6, -3, 0, 3 \)
• \( y: -30, -21, -12, -3 \)

Checking for common \( y \) values for both tables:

• At \( x = 3 \):

  • Table 1: \( y = 14 \)
  • Table 2: \( y = -3 \) (no match)

• At \( x = 0 \):

  • Table 1: \( y = 2 \)
  • Table 2: \( y = -12 \) (no match)

• At \( x = -3 \):

  • Table 1: \( y = -10 \)
  • Table 2: \( y = -21 \) (no match)

• At \( x = -6 \):

  • Table 1: \( y = -22 \)
  • Table 2: \( y = -30 \) (no match)

To find if they're representing down to one from the options restructuring:

• The solutions must yield logical spots through the given clauses.

The feasible options from choices:

1. \((-13/3, -25)\)
2. \((-14/3, -54)\)
3. \((-13, -50)\)
4. \((-14, -54)\)

Checking for a need on output: Through \( x \) analysis to match towards next items, they leave distinct equivalency. No direct fits yield feasible values for interactions that correspond—leaving matching to test through:

The best matched actual solution comparing to lineal relay proves mutual drop: thus would agree \( (-14, -54) \) yields layers of indication placed in pure evaluation leading proportional expectations drawn off content available.

Elliot has a total of 26 books. He has 12 more fiction books than nonfiction books. Let x represent the number of fiction books.

Which equation represents the situation?

How many fiction books does Elliot have?

How many nonfiction books does Elliot have?

Let's break down the information given:

1. Let \( x \) represent the number of fiction books.
2. According to the problem, Elliot has 12 more fiction books than nonfiction books. Therefore, the number of nonfiction books would be \( x - 12 \).
3. The total number of books that Elliot has is 26.

We can now set up the equation based on the total number of books:

\[ x + (x - 12) = 26 \]

Now, let's simplify and solve this equation:

1. Combine like terms: \[ 2x - 12 = 26 \]

2. Add 12 to both sides: \[ 2x = 38 \]

3. Divide by 2: \[ x = 19 \]

So, Elliot has 19 fiction books.

To find the number of nonfiction books:

\[ \text{Nonfiction books} = x - 12 = 19 - 12 = 7 \]

Thus, Elliot has 7 nonfiction books.

Summary:

• Equation representing the situation: \( x + (x - 12) = 26 \)
• Number of fiction books: 19
• Number of nonfiction books: 7
