How to solve such questions?
Such Questions can be easily solved just by some Algebraic manipulations and simplifications. We just try to make our expression in the form which question asks us. This is the best method to solve such questions as it will definitely lead us to correct answers. One such method is completing the square method.
Completing the square is a method that is used for converting a quadratic expression of the form
to the vertex form
. The most common application of completing the square is in solving a quadratic equation. This can be done by rearranging the expression obtained after completing the square:
, such that the left side is a perfect square trinomial
= 
=
(Completing Square method)
=
On comparing with the given equation we get
p = -
and q = 
∴
= 
= - 34

Answer:
x = -11
Step-by-step explanation:
7x-8 = 14+9x
7x - 8 - 7x -14 = 14 + 9x -7x -14
-22 = 2x
x = -11
Answer:

Step-by-step explanation:
I'm pretty sure it's right hope this helps
1. Slope = rate of change
Shown on the graph, for 2016 there are 36 entries. For 2017, there are 40
Since it’s only one year
You can subtract 36 from 40
40 - 36 = 4
Solution: the slope is 4
2. Months increase the most, the lines which are steeper and going upward (since it’s increasing)
Solution: from 2015 to 2016
