Miss hernandez is taking her children and their friends to the movies she will pay $10 for her adult ticket and $7 for each child ticket miss hernandez does not want to spend more than $40 which inequality can be used to find see the number of child tickets miss hernandez can purchase

The inequality is

Step-by-step explanation:

Let

x-----> the number of child tickets

we know that

-----> inequality that represent the situation

Solve for x

The maximum number of child tickets is 4

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

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.
