Answer:
49.47
Step-by-step explanation:
Take what she started with and subtract what she ended with
428.25 - 378.78
49.47
This is the amount she spent
For this case we have to:
x: Be the variable that represents the largest number
y: Be the variable that represents the smallest number
We propose a system of equations:
From the first equation we have to:
Substituting in the second equation:
We look for the value of "x":
Answer:
Answer:
1; is 20 2 is 50 3 is 18 4 is 9 and 5 is 16
Step-by-step explanation:
Multiply out <span>f(x)=(x-8)(x-2): f(x) = x^2 - 8x - 2x + 16, or f(x) = 1x^2 - 10x + 16.
Thus, a=1, b= -10 and c=16.
One of several ways to find the vertex involves "completing the square."
x^2 - 10x + 16 = x^2 - 10x + 25 - 25 + 16, or y = (x-5)^2 -9, or y+9=(x-5)^2.
Compare this result to y-k = a(x-h)^2. We see that h=5 and k=-9.
Thus, the vertex is at (h,k) = (5, -9). </span>
Answer:
375 meter square
Step-by-step explanation:
as area od 2D square is
Length * height
so we have 15 meters * 25 meters =375 meters sqaured
