(m-3)/(7)=(m)/(m+8) Solve the proportion.

ExtremeBDS [4]

Answer: m=6, m=-4

Step-by-step explanation:

To solve this proportion, we have to cross multiply.

$\frac{m-3}{7} =\frac{m}{m+8}$

$(m-3)(m+8)=7m$

Now that we have cross multiplied, we actually need to FOIL the left side to expand the equation.

$m^2+8m-3m-24=7m$

Combine like terms.

$m^2+5m-24=7m$

We can move all terms to one side and then solve for m.

$m^2-2m-24=0$

We can actually factor this to:

$(m-6)(m+4)=0$

We set each factor equal to 0 to find m.

m-6=0

m=6

m+4=0

m=-4

How to find the slope of (0,7) and (5,9)?

bekas [8.4K]

Answer:

The slope is 2/5 (0.4).

Step-by-step explanation:

The formula for finding a slope is m = (yB - yA)/(xB - xA). That equation becomes:

m = (9 - 7)/(5 - 0)

Subtract 7 from 9 to get 2.

m = 2/(5 - 0)

Any number subtracted by 0 equals itself.

m = 2/5, or 0.4 is the final answer.

If x+y is rational,must x and y each br rational?

aniked [119]

Answer:

No.

Step-by-step explanation:

$x$ and $y$ could be irrational and $x+y$ be rational.

Example:

Let $x=\sqrt{2}$ and $y=-\sqrt{2}$ .

And $x+y=\sqrt{2}+-\sqrt{2}=0$ and 0 is rational.
