Isolate I for the literal equation V = IR

1 answer:

3 0

In order to isolate any term from an equation we need to clear out any different variable or numbers different from the one we want

$V=IR$

in this case I is being multiplied by R, so we need to do the opposite which is divide in order to eliminate

$V=\frac{IR}{R}$

But since this is an equality we must do it on both sides so de equation does not get altered

$\frac{V}{R}=\frac{IR}{R}$

Then we simplify the equation

$I=\frac{V}{R}$

Answer:

Triangle DEF is a right, scalene triangle. It is not isosceles, obtuse, acute, or equilateral

Step-by-step explanation:

All we know about m and n are that they are not equal to each other and they are positive. This was given in the problem. See image. Once it is graphed you can see on the graph the lengths of DE and EF. Use Pythagorean theorem to calculate DF. see image.

DE is horizontal and EF is vertical, so you can see their slopes or calculate using a formula. Calculate the slope of DF. Slope is y-y on top of a fraction and x-x on the bottom of the fraction.

Lastly, use midpoint formula to find the midpoints. Average the x's and average the y's to find the x- and y-coordinates of the midpoints. See image.

Finally, DEF is a right triangle. The graph as well as the slopes show us that DE and EF form a right angle. So DEF must be a right triangle (and not obtuse nor acute) We were told that m doesNOT equal n, so the triangle cannot have two equal sides, so it cannot be isosceles (2 equal sides) nor equilateral (3 equal sides) It has 3 different lengths of sides; that is called scalene.
