Answer: 20−12/3=?16
16=16
True
Step-by-step explanation: hope this help:)
First, we have two points and we need to use these points to find the slope. To do this, let's label one point x1 and y1, the other point x2 and y2 then,
Slope = (y2 - y1) / (x2 - x1)
(2, 3) - 2 is x1 and 3 is y1
(-1, -12) -1 is x2 and -12 is y2
Slope = (-12 - 3) / ( -1 - 2) = -15 / -3 = 5
Now the equation of our line is: y = 5x + b
Let's plug one of our points into this equation to solve for b.
3 = 5(2) + b
3 = 10 + b
Subtract 10 from both sides.
-7 = b
The equation of our line is: y = 5x - 7
Answer:
yes
Step-by-step explanation:
x isnt a number
X = 12 y = 5... to get r you'll add 12^2 + 5^2 = r^2. From there you just place the numbers in trig functions.. sin= y/r cos=x/r tan=y/x csc=r/y and so on. If you draw the triangle it's much easier than it looks here.
