<h3><u>The two inequalities are:</u></h3>
Let "a" be the number of adult sized t shirts
Let "c" be the number of child sized t shirts
Given that,
Each Adult sized t shirts = $ 5
Each child sized t shirts = $ 2.50
<h3><u>Jerome need at least 200 adults t-shirt</u></h3>Therefore,
Here, we used "greater than or equal to" symbol, since he needs atleast 200 adult t-shirts
<h3><u>Jerome will spend no more than $1500 on t-shirt</u></h3>Therefore,
Here we used, "less than or equal to" symbol, since he will not spend more than 1500
Thus the two inequalities are found
Answer:
Given equation are:
......[1]
.....[2]
- The two lines are parallel lines then their slopes will be equal.
- When two lines are perpendicular then, the slope of lines are the negative reciprocals of each other.
Now, Equation of a line is in the form of y =mx+b where m is the slope of the line.
Slope of equation of line in [1] is;
then;
Slope of equation of line in [2];
Add both sides 2x we get;
-2x + 8y + 2x = 2x + 4
Simplify:
8y = 2x +4
Divide both sides by 8 we get;
then;
Therefore, the given two lines are neither parallel nor perpendicular.
