Spencer buys 20 strawberries to make smoothies. each smoothie needs 5 strawberries. use a count -by to find the number of smoothies spencer can make.

4

Step-by-step explanation:

If each smoothies needs 5 strawberries and we have 20 strawberries we can determine the number of smoothies Spencer can make by dividing the number of strawberries that Spencer has and the number of strawberries needed:

Spencer can make 4 smoothies with 20 strawberries.  

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:

well if he bought them at 5 cedis each sold them at 7 cedis each then he would make a profit of 2 cedis of each book. if in total he made 150 cedis profit that means he sold 75 books. he lost 12 books at the start so that means he originally bought a total of 82 books.
