Step-by-step explanation:
y = -5/6x - 4
(0,-4) is the y intercept
the slope is -5/6, it descends 5 and goes 6 horizontally.
The answer is ( < ) I believe.
Answer:
33
Step-by-step explanation:
A group of k elements can be chosen from a group of n elements in

ways.

There are 20 different 3-member groups.
Pythagoras’ theorem
a^2 + b^2 = c^2
Where a and b are two sides on a triangle and c is the hypotenuse.
Rearrange to find one to the sides that isn’t the hypotenuse.
a^2 = c^2 - b^2
a^2 = 25^2 - 10^2
a^2 = 625 - 100
a^2 = 525
(square root)
a = √525
= 5√21
