Answer:
m>-20
Step-by-step explanation:
to leave m alone you need to multiply -2 to the other side but when you do that the sign changes because its by a negative.
Formula (y1-y)=m(x-x1)
hence,
5\2-y=-1\2[x-(-2)]
-y=-1\2x-1-5\2
y=-(-1\2x-7\2)
y=1\2x+7\2
2y=x+7
Answer:
x= 4.2
Step-by-step explanation:
2/3x^2=23-15
2/3x^2=8
Sq. root both sides
2/3x = 2.8
multiply both sides by 3
2x= 8.4
divide both sides by 2
x= 4.2
