Answer:
Freddie would have walked 25 miles after 12 and a half hours.
Step-by-step explanation:
Given that Freddie is walking at a constant speed, and after 2 hours he walked 4 miles, while after 4 hours he walked 8 miles, to determine how long he walked 25 miles, the following calculation must be performed:
4/2 = Miles per hour
2 miles per hour
2X = Y
2X = 25
X = 25/2
X = 12.5
Therefore, Freddie would have walked 25 miles after 12 and a half hours.
Water freezes at 32 degree Fahrenheit.
Step-by-step explanation:
Given,
Formula for Celsius to Fahrenheit = 
x = Celsius temperature
Boiling point of water = 0°C
We will put x=0
0°C = 
0°C = 0+32
0°C = 32 degree Fahrenheit
Water freezes at 32 degree Fahrenheit.

The two sets of parametric equations for the rectangular equation are;
- If x=t+6 then y= t²-7t-42.
- If x=7t then y= 49t² - 133t +36.
<h3>What are the parametric equations from the rectangular equation?</h3>
It follows from the task content that the parametric equations can be determined as follows;
By substituting the x= t+6 into the rectangular equation; we have;
y = (t+6-6)²-7(t+6)
y = t²-7t-42.
By substituting the x= 7t into the rectangular equation; we have;
y = (7t-6)² -7(7t)
y = 49t² - 84t +36 - 49t
y = 49t² - 133t +36.
