Step-by-step explanation:
(x - 7)(y - 9)
x*(y - 9) - 7*(y - 9)
x*y - x*9 - 7*y -7*(-9)
xy - 9x - 7y + 63
That's the product.
Answer:
c > 9
Step-by-step explanation:
Isolate the variable, c. Treat the greater than sign as an equal, what you do to one side, you do to the other. Add 7 to both sides:
c - 7 > 2
c - 7 (+7) > 2 (+7)
c > 2 + 7
c > 9
c > 9 is your answer.

Answer:
This is incomplete, but i will answer it in a general way.
A function is something like y = f(x)
You can think in a function like a "machine", that eats an input (x) and transforms it into an output (y).
The functions have a rule: For all the possible inputs, the function can transform them into only one output.
This means that if we have for an input x1.
f(x1) = y1 and f(x1) = y2
So f(x) maps x1 into two different values, y1 and y2, then this is not a function.
Now, you want to change the point (1, 4) of a relationship in order to transform it into a function (so in the relation R we have two points with x = 1, and differet values of y). Then you need to choose the option that in the x-component does not have the same value that one of the other data points of the relation.
