Answer:
Step-by-step explanation:
The vertex form for a quadratic equation has the following form:
Where the vertice of the equation is the point (h, k)
To transform the equation 
in its vertex forms we must find its vertex.
Be a quadratic equation of the form:
Where a, b and c are real numbers, then the vertex of the equation will be:
For the given equation:
Therefore the vertice is:
Now we substitute x = 6 into the equation and find the value of k.
Therefore the vertice is: (6, -16)
And the equation is:
Answer:
300kg
Step-by-step explanation:
240(25/100)
240(.25) = 60
25% of 240 = 60, so add that 60 to get an extra 25% for this month
240 + 60 = 300
Answer:
Sqrt 80 = 8.94
Step-by-step explanation:
d = sqrt[(x-x)^2 + (y-y)^2]
d = sqrt [(6-2)^2 + (-9 - - 1)^2]
d = sqrt [(4)^2 + (-8)^2]
d = sqrt (16 + 64)
d = sqrt 80
d = 4 sqrt 5 = 8.94
Answer:
-5.5 
4.5
Step-by-step explanation:
Given:
The numbers to order from least to greatest is given as:
In order to compare these numbers, we have to convert them in same form.
Let us simplify each number in decimal form.
So, the least number is one which has the largest value with a negative sign.
Here, -5.5 is the least number.
The next smallest number is -4.47. So,
The next smallest number is 2. So,
The next smallest number is 3.14. So,
The greatest number is 4.5.
Therefore, the order from the least to greatest is:
-5.5 < < < < 4.5
Answer: y - 4x = 9 <em>in standard form is</em> -y + 4x = -9
