Sam answered 5 questions incorrectly on atest. For each
incorrect answer 3 points were
deducted from a score of 100.
What was Sam's Score?

If Sam incorrectly answered 5 questions, and for each question 3 points were deducted, a total of 5x3, or 15 points were deducted.

Sam scored an 85.

Let me know if this helps!

85

Step-by-step explanation:

Total points = 100

Deducted points = 5*3 = 15

Sam's score = 100 - 15 = 85

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7

step-by-step explanation:

because i took test

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.
