<span>The pattern being formed is such that the number before the plus sign is being multipled to the sum of the number after the plus sign and 1. For example, 1 * (4 + 1) = 5. 2 * (5 + 1) = 12. 3 * (6 + 1) = 21.
Applying the same principle for the given question, 8 * (11 + 1) = 8 * 12 = 96.Hope this helps. Let me know if you need additional help!</span>
Answer:
X = 20 and Y = 5
Step-by-step explanation:
you're supposed to substitute the numbers it so the problem x * 2 also means 10 * 2 because x = 10 and y * 1 also means 5 * 1 because y = 5
Answer:


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 
Answer:
y = 5/7 x -5
Step-by-step explanation:
X/7- y/5=1
Multiply each side by 35 to clear the fractions
35(X/7- y/5) =1*35
5x - 7y = 35
Subtract 5x from each side
5x-5x-7y = -5x+35
-7y = -5x+35
Divide each side by -7
-7y/-7 = -5x/-7 +35/-7
y = 5/7 x -5
