James found a puppy today . now he has 4 more puppies than his sister cara .(1) write an expression to represent the number of puppies james has .let c represent the number of puppies cara has (2)write an expression to represent the number of puppies cara has . let j represent the number of puppies james has .(3)if james has 7 ppuppie how many does cara have ?

what are the things "represented below"?

step-by-step explanation:

nobody can if you dont give the choices

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.

step-by-step explanation:

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
