Answer:
Hello, In elementary geometry, the property of being perpendicular (perpendicularity) is the relationship between two lines which meet at a right angle (90 degrees). The property extends to other related geometric objects. A line is said to be perpendicular to another line if the two lines intersect at a right angle.
Hope this helped!!
Given that S<span>hanley would like to give $5 gift cards and $4 teddy bears as party favors and that Shanley has $128 to spend on party favors.
The inequality to find the number of </span><span>gift cards x and teddy bears y Shanley could purchase</span> is given by

One solution to the inequality is that Shanley can buy 12 gift cards and 15 teddy bears.
Not sure what form you want this in:
Simplified this is 4x+4y
Factorised this is 4(x+y)
{y|1 > y}, (-∞, 1); you did not specifically mention what notation you needed, so I wrote both [Internal Notation and Set Notation].
