Nia sells pizzas. large pizzas cost
$8 each, and small pizzas cost $6 each.
she sold 12 pizzas for $84. how many
of each size pizza did nia sell?

Nia sold 6 large pizzas and 6 small pizzas.

Step-by-step explanation:

x+y=12

8x+6y=84

x=12-y

8(12-y)+6y=84

96-8y+6y=84

96-2y=84

2y=96-84

2y=12

y=12/2

y=6

x+6=12

x=12-6=6

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
