Hey!
-----------------------------------------------
Solution:
= (-18) - (4)
= -18 - 4
= -22
When you subtract a positive to a negative number the end result will always be negative.

Hope This Helped! Good Luck!
There is no picture, wondering your asking to be explained :)
In standard form the two equations are
7x +y = 5
7x +y = -5
The equations describe lines that are parallel.
The function y = 2.5x + 500 represents the total number of miles if the motor car race is 500 miles long, option (d) is correct.
<h3>What is a function?</h3>
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have:
y represents the number of miles a motor car has left to go in the race
x represents the number of laps completed by the motor car
The total number of miles if we consider only circular speedways = 2.5x
The total number of miles:
y = 2.5x + 500 (because 500 is the constant)
Thus, the function y = 2.5x + 500 represents the total number of miles if the motor car race is 500 miles long option (d) is correct.
