Answer:

A. x = 6.08, x = -0.58

Step-by-step explanation:

[tex]\displaystyle \frac{2x}{x-4}-\frac{2x-5}{x^2-10x+24}=\frac{-3}{x-6}[/tex]

1. Factor the denominator.

[tex]\displaystyle \frac{2x}{x-4}-\frac{2x-5}{(x-6)(x-4)}=\frac{-3}{x-6}[/tex]

2. Multiply the leftmost fraction by (x-6)/(x-6) to get common denominators.

[tex]\displaystyle \Big ( \frac{x-6}{x-6} \Big ) \frac{2x}{x-4}-\frac{2x-5}{(x-6)(x-4)}=\frac{-3}{x-6}[/tex]

3. Simplify.

[tex]\displaystyle \frac{2x^2-12x}{(x-4)(x-6)}-\frac{2x-5}{(x-6)(x-4)}=\frac{-3}{x-6}[/tex]  

4. Combine like terms.

[tex]\displaystyle \frac{2x^2-14x+5}{(x-4)(x-6)}=\frac{-3}{x-6}[/tex]  

5. Multiply the right side of the equation by (x-4)/(x-4).

[tex]\displaystyle \frac{2x^2-14x+5}{(x-4)(x-6)}=\frac{-3}{x-6} \Big ( \frac{x-4}{x-4} \Big )[/tex]  

6. Simplify.

[tex]\displaystyle \frac{2x^2-14x+5}{(x-4)(x-6)}=\frac{-3x+12}{(x-6)(x-4)}[/tex]

7. "Cancel" out the denominators because they are equivalent.

[tex]2x^2-14x+5=-3x+12[/tex]

8. Set the equation equal to 0.

[tex]2x^2-11x-7=0[/tex]

Quadratic formula:

[tex]\displaystyle x = \frac{-b\pm \sqrt{b^2-4ac} }{2a}[/tex]  

9. Factor using the quadratic formula.

[tex]\displaystyle x = \frac{-(-11)\pm \sqrt{(-11)^2-4(2)(-7)} }{2(2)}[/tex]

10. Multiply and simplify.

[tex]\displaystyle x = \frac{11 \pm \sqrt{177} }{4}[/tex]

11. Plug this into your calculator and solve for x.

[tex]x=6.07603367 \approx 6.08[/tex] [tex]x=-0.57603367 \approx -0.58[/tex]

The correct answer is A. x = 6.08, x = -0.58.

Question 12 (1 point) Johnny says the sequence below is (A) Arithmetic because it has a common difference. He also says the first term is 100. (B) Do you agree? a 65 – 100n (A) Is it arithmetic? (B) is the first term 1007 if not what is the first term?​

Answers

Answer:

The sequence is Arithmetic because it uses subtraction.

The first term is a(1) = 65 since it comes first in the formula.

Step-by-step explanation:

We are given the equation 65-100n. 65 is the first term since it comes first in the arithmetic formula and 100n is the common difference. So the correct answer should be an arithmetic sequence and 65 as the first term.

If f(x) = 2x - 5 , Find f(3).
Substitute 3 for x then type your final answer.

Answers

Answer:

f(3) = 1

Step-by-step explanation:

To find f(3), plug in 3 as x and simplify the expression:

f(x) = 2x - 5

f(3) = 2(3) - 5

f(3) = 6 - 5

f(3) = 1

So, f(3) = 1
