Answer:
B
Step-by-step explanation:
A. x^2 - 2x - 8 < 0
(x - 4)(x + 2) < 0
B. x^2 + 2x - 8 < 0
(x + 4)(x - 2) < 0
C. x^2 - 2x - 8 > 0
(x - 4)(x - 2) > 0
D. x^2 + 2x - 8 > 0
(x + 4)(x - 2) > 0
Since roots here are -4 and 2, the answer is either B or D.
When you test a point in the interval between -4 and 2, for example 0, it is negative.
So the answer is B.
Answer:
This correlation simply means that, in every twin whether identical or fraternal twins, there is a relation between their IQ scores and when they are raised together.
Regarding to the test carried out, it showed that, when an identical twin is raised together, their IQ score tends to be higher in direct comparison with a fraternal twin that was raised together. <em>That is, if the fraternal twin IQ is 100, then, the identical twin IQ is going to be above 100 (probably around 120)</em>

Answer:
Slope = -7/2
y intercept = -91/4
Step-by-step explanation:
Given the line
x = 
- 
y
We know that in the equation y = mx + c, m is slope and c is y intercept,
So bring the given equation to above form,
x = - y
x = 
14x = -91 -4y
4y = -14x-91
y = 
comparing above equation with y= mx+c
slope, m = 
= 
y intercept, c =
