Answer:
b. 4+7x-2
Explanation:
when you add like terms for the first equation it becomes 7x-6
the second one becomes 7x+2
the third one becomes 7x-6
and the last one is also 7x-6
which means the second one is not equivalent
The answer for the question in problem would be $125 is the price of hotel per night. This is computed by establishing the equations from the given statements, 3x + 4y = 625 and 4x +5y = 875. And by substitution you would get the answer of 125 as the price per night n the hotel and 75 per day for the rental of car.

Answer:
C. 
Step-by-step explanation:
In order to find the slope knowing two points, use the slope formula 
. 
and 
represent the x and y values of one point the line intersects, and 
and 
represent the x and y values of another point the line intersects.
Knowing this, use the points (-4, -4) and (6, 4) for the formula. Substitute -4 for , -4 for , 6 for , and 4 for . Then, simplify:
Thus, is the slope of the line.
