Answer 1

Solving the System of Equations

To solve the system of equations x - y = 6 and x + y = 10, we can use the method of substitution or elimination. Let's use the method of substitution.

1. Start with the first equation: x - y = 6. 2. Solve this equation for x: x = 6 + y.

Now, substitute the value of x in the second equation:

x + y = 10

Substituting x = 6 + y:

(6 + y) + y = 10

Simplifying the equation:

6 + 2y = 10

Subtracting 6 from both sides:

2y = 4

Dividing both sides by 2:

y = 2

Now, substitute the value of y back into the equation x = 6 + y:

x = 6 + 2

Simplifying:

x = 8

Therefore, the solution to the system of equations is x = 8 and y = 2.

Let's verify the solution by substituting the values of x and y back into the original equations:

1. For the equation x - y = 6: - 8 - 2 = 6 (True)

2. For the equation x + y = 10: - 8 + 2 = 10 (True)

Therefore, the solution x = 8 and y = 2 satisfies both equations.

Answer to Additional Questions

1. The function that is parallel to the graph of the given function cannot be determined without additional information or the graph itself. Please provide more details or the graph for further assistance.

2. To find the sum of all terms in a geometric progression, we can use the formula:

Sum = b1 / (1 - q)

Given that b1 = 4 and q = 1/3, we can substitute these values into the formula:

Sum = 4 / (1 - 1/3)

Simplifying:

Sum = 4 / (2/3) = 4 * (3/2) = 6

Therefore, the sum of all terms in the geometric progression is 6.

3. To solve the inequality 3x - 1 + 5 + x - 3 - x + 2 ≤ 15 + 6, we can simplify both sides of the inequality:

3x - 1 + 5 + x - 3 - x + 2 ≤ 15 + 6

Combining like terms:

3x + x - x - 1 + 5 - 3 + 2 ≤ 15 + 6

Simplifying:

3x - 1 + 5 - 3 + 2 ≤ 15 + 6

3x + 3 ≤ 21

Subtracting 3 from both sides:

3x ≤ 18

Dividing both sides by 3:

x ≤ 6

Therefore, the solution to the inequality is x ≤ 6.

4. To find the range of the function y = (2x^2) + (8/x^2), we need to determine the possible values of y for all valid values of x. Since the function involves a quadratic term and a reciprocal term, we need to consider the restrictions on x.

The quadratic term 2x^2 can take any positive or negative value, so there are no restrictions on it.

However, the reciprocal term 8/x^2 cannot be zero, so we need to exclude any values of x that make the denominator zero. In this case, x ≠ 0.

Therefore, the range of the function is all real numbers except 0.

I hope this helps! Let me know if you have any further questions.
