If this is a T/F question, then your answer is True .-.
Answer:
y= -x + 15 x<0
y= x+ 15 x>/ 0
Step-by-step explanation:
C because K is 1,-8 so if you go up 1, -7, and right 4,5. So you get k(5,-7)
X - the amount of money Nina has
y - the cost of one widget
Nina has exactly enough money to purchase 6 widgets.
If the cost of each widget was reduced by $1.25 (so the cost of one widget would be y-1.25), Nina would have exactly enough money to purchase 8 widgets.
Substitute 6y for x in the second equation:
Nina has $30.
