B*D?
B=-2
D=-6
B*D=(-2)*(-6)=12
The total angle sum of a triangle is 180°
As such, 180= 78 + 2s +4s
102= 6s
s=17
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
Answer:
The answer will be 2x-12
Step-by-step explanation:
Hope this Helped
It is y=x-150 because x−150+150=y+150
