Mr. Davis treated his team to a pizza party after their last baseball game. He bought 7 cheese pizzas and spent less than $70.00. Write and solve an inequality to find the cost of each pizza.

About $10 for each Pizza.

Step-by-Step:

We can use the equation 7a=70 to solve the problem. a= Amount. We divide 7 on both side which is 10. So a=10.

step-by-step explanation:

0

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
