1+4=5 2+5=12 3+6-21 8+11=
Answers
This is a common math problem. There are two ways to answer this question but both will give you the same answer. There is a misconception that this can also equal 40. If someone posts that the answer is 40, please let me know and I will explain why that is not actually the answer.
1+4=5
2+5=12
3+6=21
8+11=
These equations are actually:
1*(4+1)=5
2*(5+1)=12
3*(6+1)=21
8*(11+1)=96
Therefore:
8+11 = 96
1(4+1)
2(5+1)=12
3(6+1)=21
8(11+1)=96
Hope this helps!

The change in x values and y values are proportional to each other for the given case. The correct option is (D).
What is the slope of straight line?
The slope of a straight line is the tangent of the angle formed by it with the positive x axis as the reference.
The negative slope indicates the rate of decrease while the positive shows the rate of increase.
In order to form a linear equation from a table,
The slope has to be found first.
For this, the ratio of the difference in the values of x and y are taken.
Which implies that the change in x values are directly proportional to the change in the values of y.
And the proportionality constant is known as the slope.
=> (y₂ - y₁) ∝ (x₂ - x₁)
=> (y₂ - y₁)/(x₂ - x₁) = m
Hence, the change in y values are constant for change in x values.

(x + 1)2 = 3(y-4)
(y-4)2 = 12(x + 1)
(y-2)2 = -3(x – 4)
(y-4)2 = –12(x - 2)

Since the graph is facing the left, the starting equation would be (y - k)2 = -4p(x - h).
(h, k) is the vertex of the graph. If you plot the focus and the directrix, you can see that the distance is 6. Divide 6 by 2, thus the vertex should be 3 squares away from the focus and 3 squares away from the directrix. The vertex is (2, 4). And since the distance from the focus to the vertex and the distance from the directrix to the vertex is 3, P = 3.
Insert the numbers in and you should get the last choice.
