P= 2(i+w) what is the solution for I?

Dafna11 [192]

First you had to switch sides of equation.

$2(i+w)=p$

Then you divide by two from both sides of equation form.

$\frac{2(i+w)}{2}= \frac{p}{2}$

Simplify.

$i+w=\frac{p}{2}$

Next, subtract by i from both sides of equation form.

$i+w-i=\frac{p}{2}-i$

Finally, simplify by equation.

$w=\frac{p}{2}-i$

Final answer: $\boxed{w=p/2-i}$

Hope this helps!

Find an equation of the line through the given pair of points. (-7,-5) and (-1,-9) The equation of the line is (Simplify your an

Phantasy [73]

Answer:

The equation of the line is y = -2/3x - 29/3

Step-by-step explanation:

The slope of these points (-7,-5) and (-1,-9) is m = -2/3

Once you plug that into the y = mx + b equation, you can see that the y-intercept is -29/3.

Put all of that into the y = mx + b equation and you'll get --> y = -2/3x - 29/3
