The table below shows the amount of money earned by two different workers over 5 consecutive days. Which equation best represents Fallon's earnings in terms of Donald's earnings? (How do you go from x to y?) A. x = 7y
B. x = y + 7
C. y = x + 7
D. y = 7x

C. y = x + 7

Step-by-step explanation:

everything on the left is 7 less then on the right

the answer on ed. is:

c. "the graph of f(x) has exactly two x-intercepts."

hope i could someone! : )

step-by-step explanation:

total income = price of one ticket   *   number of tickets sold

  y                 =     4                                   x

so the equation is y=4x     with x≥0   because number of tickets sold can not be negative

thus the equation is a semi -line with an end point at

(0,0)

passing through :

x=1     y=4(1) = 4   so through (1,4)
