(3x+7)(x-1)=0
3x+7=0
x= -7/3
x-1=0
x=1
Answer: -1/5
Step-by-step explanation:
the equation to solve slope with two points is the y coordinate in the second point minus the y coordinate in the first point over the x coordinate in the second point minus the x coordinate in the first point so this one would be
(-2 - -1)/(12-7)
On the top you subtract a negative it becomes a positive and you get -1/5
5t = 25+2r
t = (25+2r)/5 or
t = 5 + (2/5)r
