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.

Reasoning Solve the system of linear equations using substitution. Use pencil and paper. Which expression would be easier to substitute into the other​ equation, in order to solve this​ problem? Explain your reasoning. x = 4y - 2 x + 4y =7

Answers

Answer:

x = 5 /2 , y = 9 / 8

Step-by-step explanation:

x = 4y - 2 ....... (i)

x + 4y =7 ....... (ii)

Substituting eqn  (i) into eqn (ii);

(4y - 2 ) + 4y = 7

4y - 2 + 4y = 7

8y = 7 + 2 = 9

y = 9 / 8

substitute y = 9 / 8 in eqn (i)

x = 4 (9 / 8) - 2

x = 9 / 2   -   2

x = (9 - 4 ) / 2

x = 5 / 2

y=-x+3 follows the same equation as y=mx+b

3 is b, and b is the y-intercept. The y intercept is where the line crosses on the y axis,  and -x is is m, which is the slope. However since its a variable, its point is on the same number as positive three on the y axis, so then its 3 on the x axis.
