Answer:
-3x + y = 2
Step-by-step explanation:
The slope is 3. So the coefficient of x is 3.
when x = 1, y = 5.
So 3*1 + c = 5
So c is 2.
So y = 3x + 2
Therefore, taking 3x to the LHS, we get,
-3x + y = 2
Hope it helps ;)
Answer:
the slope is 1/2
Work:
if the x-coordinate is two times the y-coordinate, that means you are going up one over two each time
slope= y2-y1/x2-x1
so you can pick two points, like (2, 1) and (4,2) and use the formula
slope= 2-1/4-2= 1/2
So if you do 6(pi) then you should get 18.84
Answer:
Algebra Review: x=-4, r =5
Step-by-step explanation:
Use distributive prop;
-3x-6=6
then add 6 to both sides to get x by itself
you get -3x=12
divide both sides by -3
you get x=-4
Again do distributive prop.
-12r+24=-36
trying to get r by itself, so subtract 24 on both sides
you get: -12r=-60
then divide -12 both sides to get r by itself and you get r=5
Pythageron Theorem:
which is a^2+b^2=c^2
a=3, b=7 and c=C^2 (this is always the long side)
so then we get 3^2+7^2=c^2
9+49=c^2
opposite of sqaring is rooting
so we get sqare root of 58 or 7.6
I'm sorry I can't help you with the angles, I would suggest looking it up and Khan Acadamy is a good resource. Good Luck!
