We have that
y = 3x²<span>+ 2x + 1
step 1</span>
Group terms that contain the same variable, and move the constant to the opposite side of the equation
y -1= (3x²+ 2x)
step 2
Factor the leading coefficient
y -1= 3*(x²+ 2/3x)
step 3
Complete the square. Remember to balance the equation by adding the same constants to each side
y -1+(1/3)= 3*(x²+ (2/3)x+(4/36))
y-2/3=3*(x+2/6)²
the vertex is the point (-2/6, 2/3)------> (-0.33,0.67)
the answer is
(-0.33,0.67)
Answer:

Step-by-step explanation:
Answer:
only 6 brownies had both chocolate and walnuts
Step-by-step explanation:
lets found out how many brownies had walnuts.
90/5= 18
18x3= 54 brownies had walnuts.
_______________________________________________
chocolate brownies.
90/3= 30 brownies had chocolate.
________________________________________
54+ 30= 84 brownies
90-84= 6
