Answer:
x=2
Step-by-step explanation:
Add 4 to both sides:
-2=-4+x
-2+4=-4+4+x
2=x
X + 2 = 12
subtract both sides by 2
x = 10
The answer is C=S+4 Because both S and C have the same rate of change you only need to find the difference of the two values.
Answer:
Relationship between distance and time in simplified form as a unit rate is; 
Step-by-step explanation:
Unit rate defined as the rates are expressed as a quantity of 1, such as 5 feet per second or 3 miles per hour, they are called unit rates.
Unit rate = 
From the given table:
Take any
time = 4 hours and distance= 188 miles
then, by definition of unit rate;
Unit rate = 
Since, this is the constant rate.
Therefore, the relationship between distance and time in simplified form as a unit rate is; 
Answer:
y = 4x - 28
Step-by-step explanation:
When two lines are parallel, their slope stays the same. thus we have y = 4x (so far)
Then use the point (8, 4) to plug in the coordinates to y = 4x + b
y = 4x + b (because y-intercept changes)
4 = 4(8) + b
4 = 32 + b
b = 4 - 32
b = -28
the y-intercept is -28 and the equation of the line that passes through the point (8, 4) and is parallel to the line y = 4x + 2 is y = 4x - 28
