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:
Rob is 18
Jake is 9
21-15=6
6+3=9
9x2=18
(No clue how I got 15 )
Answer:
784m^2
Step-by-step explanation:
is a rectangle with sides of 40m and 20m, in the upper right corner a right triangle has been removed with the legs of: 40 - 32 = 8m and 20 - 16 = 4m, we find the area of the rectangle (b * h).
40 * 20 = 800m ^ 2, then we find the area of the right triangle
1/2 b * h: 1/2 8 * 4 = 16 m ^ 2.
we remove the area of the triangle from the rectangle and we have the area of the figure: 800 - 16 = 784m^2
Answer:
$8.50
Step-by-step explanation:
I don't know what Alls are, but if Carlos insists, we can calculate how much he can spend on Alls with the expression:
($31.50) + r 
$40
This says the sum of what Carlos has already spent (hot dogs and hamburgers) plus the amount he spends on Alls (rolls?), r, must be equal to or less than the $40 he has allowed himself to spend.
($31.50) + r $40
r $40 - $31.50
r $8.50
