If the legs are length a and b and hyptonuse is c then
a²+b²=c²
so
if the legs are 20 and 21 and the hypotnuse is x then
20²+21²=x²
400+441=x²
841=x²
29=x
There is 1 branch per 2 inches.
1 foot is 12 inches, that means there are 6 branches in 1 foot.
6 branches multiplied by 6 is 36.
There are 36 branches on the tree.
-8x-8y=0 (divide both sides by -8, you get:) x+y=0, x=-y
-8x2y=-20 (divide both sides by -16:) xy=20/16=5/4
plug the first simplified equation into the second one,
-y²=5/4...This does not have a solution, are you sure you typed the second equation correctly?
58 the 5 is 50 and the 8 is just 8 . the 5 is in the 50s place and the 8 is in the ones place
For this case we have that by definition, the equation of the line of the slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cut-off point with the y axis
We have two points through which the line passes:
We found the slope:
Substituting we have:
Thus, the equation is of the form:
We substitute one of the points and find the cut-off point:
Finally, the equation is:
