The cost of one French silk cheesecake is $5 and one apple cheesecake is $14.
Step-by-step explanation:
Let,
Cost of one French silk cheesecake = x
Cost of one apple cheesecake = y
According to given statement;
8x+y=54 Eqn 1
3x+y=29 Eqn 2
Subtracting Eqn 2 from Eqn 1
Dividing both sides by 5
Putting x=5 in Eqn 1
The cost of one French silk cheesecake is $5 and one apple cheesecake is $14.

Answer:
D
Step-by-step explanation:
a "function" gives every x value exactly one y value.
A, B and C all have 2 or more y values for an x value.
use e.g. a pen and place it vertically (straight top-down, parallel to the y-axis) on the graphs.
how often does the pen intersect the function curve ?
that is what I am talking about.
if it is more than once, than the x value (the point on the x-axis), where you put your pen, has more than 1 y values.
and that is then not a function.
only D is a function. the pen intersects with the function curve only once, no matter where you put the vertical pen.
