Answer:


Step-by-step explanation:
Given
See attachment for grid
Required
Find c and d
From the attachment, we have:
--- Point on A
--- Corresponding point on B
When A is reflected across the x-axis, the rule is:

So, we have:

Next, is to calculate the translation from
to 
This is calculated using:

and

So, we have:


---- i.e. Shift by 6 units to the left


--- i.e. Shift by 1 unit down
Answer:
x > 3
Step-by-step explanation:
The inequality to solve is:
5 - 4x < - 7
We will solve this using same method as solving an equation. We will take numbers to one side and variables to another and multiply and divide accordingly.
So,

That means "x is greater than 3", so we can write:
x > 3
Answer:
Yes
Step-by-step explanation:
Because 6.3hours is still in the range 5.5+/-1.8 hours
Therefore the result support the findings of the study.
