Answer:
x= -2 x=-2
Step-by-step explanation:
move over the leading coefficient and you get
3x²+12x+12
the pull out a 3 because that's your gcf and 3 cannot equal zero so you can just do without id and you get
x²+4x+4
and when you factor that you get
(x+2)(x+2)
and when you set those equal to zero you get x= -2 and x= -2
Answer:
y = 3x + 3
Step-by-step explanation:
The equation of a line is: y = mx + c where m is the slope of the line and c is the y-intercept of the line. I will calculate the slope using the points (0, 3) and (1,6)
Slope = 
= 
= 3
The y-intercept, based on the graph, is 3. Thus, the equation is: y = 3x + 3.
Answer:
