You would have to find this out by multiplying the reciprocal of 3/4 which is 4/3 to 3/4 and one to get your answer that is 1
I think .. correct me if i’m wrong
1. 3x+75=165
2. 3x+200
Answer:
Cartesian plane
Step-by-step explanation:
(–1 , 3)
Answer:
x+3y=-1
Step-by-step explanation:
y=3x-2 so m=3 old slope
the new slope must be -1/3 (opposite reciprocal of the old slope).
y-y0=m*(x-x0)
y-2=-1/3*(x-(-7))
y-2=-1/3x-1/3*7
y-2=-1/3x-7/3
3y-6=-x-7
The standard form for linear equations in two variables is Ax+By=C.
x+3y=6-7
x+3y=-1
So, we know the center is at -1, -3, hmmm what's the radius anyway?
well, the radius will be the distance from the center to any point on the circle, it just so happen that we know -7, -5 is on it, thus
