Answer:
16
Step-by-step explanation:
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:
4005
Step-by-step explanation:
Cost of goods available for is equal
80000+160000=240000
Retail value is equal
100000+200000=300000
This means that the cost of goods sold is 80% (240000÷300000) and gross profit is 20%
Sales= 250000 and it's cost is equal 200000 (250000×0.8)
Ending inventory
=240000-200000=40000...answer
Hope it helps!
