The cost of one sweatshirt is $19.
Step-by-step explanation:
Let,
Cost of one pair of jeans = x
Cost of one sweatshirt = y
According to given statement;
5x+2y=233 Eqn 1
3x+4y=193 Eqn 2
Multiplying Eqn 1 by 2
Subtracting Eqn 2 from Eqn 3
Dividing both sides by 7
Putting x=39 in Eqn 2
Dividing both sides by 4
The cost of one sweatshirt is $19.

Answer:it is 12
Step-by-step explanation:the way it works is you add them up and get 12
The vertex of a linear absolute function is located at the point where the absolute function is zero.
Here |x+5|=0 => x=-5
At x=-5, y=-1.
So the ordered pair of y=|x+5|-1 is (-5,-1)
