the hypotenuse of a right leg triangle is 12 centimeters, and the shorter leg is 6 centimeters. Find the length of the other leg

1 answer:

5 0

Well that's quite easy. There is a short cut. So 12 divided by 2 is 4. Then 6 divided by 2 is 3. There is a thing called a Pythagorean Triple. And the first one is 3,4 (which is the missing side) and 5. That is the most commonly used set and so are the number's multiples. Therefore the missing leg's length is 4 centimeters.

What is the equation of the line that passes through (-3, -1) and has a slope of 2/5? Put your answer in slope-intercept form.

Zanzabum

Hi there!

The general formula of A line in slope-intercept form is the following:
$y = mx + n$

In this formula m represents the slope of the line. Therefore, we can conclude that m = 2/5.
$y = \frac{2}{5} x + n$

We also know that the line passes through the point (-3, -1) and we can therefore substitute this coordinate into the formula of the line.
x = -3 and y = -1

$- 1 = \frac{2}{5} \times - 3 + n$

Multiply first.
$- 1 = - 1\frac{1}{5} + n$

And finally add 1 1/5 to both sides of the equation.
$\frac{1}{5} = n$

We can now switch sides.
$n = \frac{1}{5}$

Now we've found our value of n, which we can substitute into the formula of our line. Hence, in slope-intercept form, we find the following:
$y = \frac{2}{5} x + \frac{1}{5}$
