Given f(x) = x 10. What is f(7)
i think its -10
what does x 10 mean?
did you mean 10x or x^10 or ....
I can't see where you get f(7) = -10
What is the solution to the linear system of equations?
x + 4y = 8
x y = 7
(4, 3)
(4, 3)
(7, 0)
The system has no solution.
Please don't attach a new question to the replies of a new question, post it as a new question.
While you are replying to my first concern, here is your second problem:
you claim that you have a linear system of equations, but
xy = 7 is not linear, it would be a curve.
Check your typing
To find f(7), simply substitute 7 into the given function f(x) = x - 10 and evaluate it.
Substituting x = 7, we get:
f(7) = 7 - 10
Now, perform the subtraction:
f(7) = -3
Therefore, f(7) is equal to -3, not -10.
