Answer:
Step-by-step explanation:
For a quadratic function to have a vertex with an x-coordinate of 3, then
Let a=1, then we have
So now our equation becomes:
We now find two factors of c that add up to -6.
Let these factors be 1, and c.
Then
Therefore the factors are :
1 and -7.
The function becomes:
The factored form is
Answer:
OB.
Step-by-step explanation:
you first find the common denominator of the two fractions. then u start dividing each denominator into the common denominator u chose and multiplying the answer with the numerator
136×25%=136×25/100= 3 400/100=34
so the markeup value is
136+34= 170
170×17%=170×17/100=2 890/100=28.9
170-28.9=141.1
Selling price=136+170=306
