DeltaMath is due Thursday night!

Asemmisa {{asɛmmisaAhyɛnsode}}

1.

Given \frac{9}{x^2+3x}. What is the domain?
(make sure to start with x \ne)

Asemmisa {{asɛmmisaAhyɛnsode}}

2.

Solve: 7+\frac{x}{x+3}=\frac{9}{x^2+3x}

Asemmisa {{asɛmmisaAhyɛnsode}}

3.

Solve: \frac{5x}{x+2}-\frac{2}{x^2+2x}=-\frac{9}{x+2}

Asemmisa {{asɛmmisaAhyɛnsode}}

4.

Solve: \frac{3}{x-1}+\frac{2x+3}{x+5}=\frac{3x}{x-1}

Asemmisa {{asɛmmisaAhyɛnsode}}

5.

Solve: 7x+\frac{1}{x}=-8

Asemmisa {{asɛmmisaAhyɛnsode}}

6.

Solve: \frac{5}{x-4}+\frac{x}{x-6}=\frac{2x}{x^2-10x+24}

Asemmisa {{asɛmmisaAhyɛnsode}}

7.

Solve: 1+\frac{7}{x+6}=\frac{7}{x^2+13x+42}

Choose all that are true

I am confident in this lesson.

I would like some assistance.

I can find the common base.

I can find the domain.

I can decide when to reject answers.
