Step-by-step explanation:
Let a and b be integers.
Sum means addition.
So we are trying to figure out what a+b equals.
It could result in as 0, negative, or positive.
a+b is 0 when a and b are of opposite values. Example: 5+(-5) or -5+5 is 0 because 5 and -5 are opposite values.
a+b is positive when both a and b are positive. Example 5+3=5.
a+b is positive when |a|>|b| and a is positive. Example: 5+(-3)=2 since |5|>|-3| and 5 is positive.
a+b is positive when |a|<|b| and b is positive. Example: -3+5=2 since |-3|<|5| and 5 is positive.
a+b is negative when both a and b are negative. Example: -5+(-3)=-8.
a+b is negative when |a|>|b| and a is negative. Example: -5+3=-2 since |-5|>|3| and -5 is negative.
a+b is negative when |a|<|b| and b is negative. Example: 3+(-5)=-2 since |3|<|-5| and -5 is negative.
Answer:
Rate of change (slope) = -5
Step-by-step explanation:
Rate of change = (-5 -0) / (-2 - - 3) = -5/1 = -5
We are given that the cost of each shirt = $12.25
It is given that she bought total 'x' shirts, each of cost $12,25.
So, the cost of 'x' shirts is dollars
Also, there is a shipping charge of $3.99
So, the total cost of 'x' shirts is
Since, the shirts cost her total $77.49.
We have the equation,
12.25x + 3.99 = 77.49
