Answer:
yes
Step-by-step explanation:
You can check to see if the numbers satisfy the Pythagorean theorem.
9² +12² ?= 15²
81 + 144 = 225 . . . . yes these segments form a right triangle
_____
You know that segments of lengths 3, 4, 5 form a right triangle. This is the first "Pythagorean triple" that most folks run across. The segments given here are all 3 times those numbers, so will also form a right triangle.
Answer:
y = -5x-3
Step-by-step explanation:
You use rise/run to simply find the m
which will be -5/1
because look at the point at (-1,2) and now move down 5 points and 1 to the right so u will reach the point that is on the y axis. so because u moved 5 down so tht is -5 and moves 1 to the right so tht is 1 and we use rise/run to write our slope. so its -5 and now we see where our point is on the y axis so that is -3. so thats our b because b means y intercept
So we're given Y = 3x.
We now can replace Y, for 3x in the equation:
Y = x + 4
3x = x + 4
3x - x = 4
2x = 4
x = 2
