Step-by-step explanation:
Given
Solving (a): In vertex form
The vertex form of an equation is:
To do this, we make use of completing the square method.
We have:
------------------------------------------------------------------
Take the coefficient of x (i.e. -6)
Divide by 2; -6/2 = -3
Square it: (-3)^2 = 9
Add and subtract the result to the equation
------------------------------------------------------------------
Factorize
Factor out x - 3
Express as squares
Hence, the vertex form of is:
Solving (b): State the coordinates of the vertex.
In ; the vertex is: (h,k)
The vertex of will be
One possible divided is the number 1236.
If 5 went into 1235 the quotient would be exactly 247. However, there needs to be a remainder. So let's just change the number to 1236. Then, there will be a remainder of 1.
Answer:
y=65; x=50
Step-by-step explanation:
x+y=115
50x+35y=4775
y=115-x
50x+35(115-x)=4775
50x+4025-35x=4775
15x=750
x=50
50(50)+35y=4775
2500+35y=4775
35y=2275
y=65
The answer is 150 grams i think
