63-9b
Step-by-step explanation:
9(7-b)
=9×7-9×b
=63-9b
9 x 7= 63
9 x b= 9b
you would save .66 per pack so .66×3=1.98
9.99÷3=3.33, 3.99-3.33=.66
5 to 9 5:9 5/9
quadratic parent function
squares cannot be negative no matter what you cannot square a number into a negative number which is why there are no negative y values because y is a function of X
