-5n=13-3m solve for m

Mathematics
1 answer:
Ket [755]3 years ago
6 0

Answer:

Step-by-step explanation:

-5n = 13 - 3m

Subtract 13 from both sides

-5n - 13 = -3m

Multiply the whole equation by (-1)

-5n *(-1) - 13*(-1) = -3m*(-1)

5n + 13 = 3m

Divide both sides by 3

\dfrac{5n+13}{3}=m\\\\\\m =\dfrac{5n+13}{3}

The slope of AB is -2/5. Segments CD has endpoints at C(-5,3) and D(10,-3). Are AB and CD parallel, perpendicular or neither? Ju
bazaltina [42]

Answer:

AB and CD are parallel

Step-by-step explanation:

AB has the slope of -2/5

lets see what slope the line CD has:

  • points are (-5, 3) and (10, -3)
  • slope= m= (y2-y1)/(x2-x1)= (-3-3)/(10+5)= -6/15= -2/5

as we see AB and CD have same slope, therefore they are parallel

Simplify the expression given below.
svet-max [94.6K]

Answer:

Option B. \frac{1}{3x+1}.

Step-by-step explanation:

The given expression is \frac{x+2}{x^{3}+2x^{2}-9x-18}\div \frac{3x+1}{x^{2}-9}

In this expression we will simplify \frac{x+2}{x^{3}+2x^{2}-9x-18} first.

=\frac{x+2}{x^{2}(x+2)-9(x+2)}

=\frac{x+2}{(x+2)(x^{2}-9)}

=\frac{1}{x^{2}-9}

Now we can rewrite the given expression as

=\frac{1}{x^{2}-9}\div \frac{3x+1}{x^{2}-9}

=\frac{1}{x^{2}-9}\times \frac{x^{2}-9}{3x+1}

= \frac{1}{3x+1}

So option B. \frac{1}{3x+1} is the right answer.
