To find the coordinates of the vertex, you use the formula x=-b/(2a)
in this case, a is 6, b is 5
x=-5/12
Next, find out the value of y when x is -5/12
y= 6(-5/12)^2 +5(-5/12) -6
y=-23/8
so the vertex is at (-5/12, -23/8)
Please double check the calculation by yourself
Answer:
inches
Step-by-step explanation:
Let x inches be the length of one side of the frame. The frame is the square, so all sides have the same lengths.
Use formula connecting the area of the square and the side length of the square.
Since the area ofthe square is 55 square inches, we have
<span> y – 2 = 4(x – 3)
y - 2 = 4x - 12
y - 2 = 4x - 12
y = 4x - 12 + 2
y = 4x - 10
y - 4x = -10</span>
12 pounds multiplied by 31 as there are 31 days in January.
So she will need 372 pounds.
