What exactly do you need help with?!
You could actually find the compositions and thus have something to compare. You haven't shared the list of possible answer choices.
(f+g)(x) = 5x - 3 + x + 4 = 6x + 1
(f-g)(x) = 5x - 3 - x - 4 = 4x - 7
(f*g)(x) = (5x-3)((x+4) = 5x^2 + 20x - 3x - 12 = 5x^2 + 17x - 12
There are also the quotient (f/g)(x) and the compositions f(g(x)) and g(f(x)).
WRite them out.
Then you could arbitrarily select x values, such as 2, 10, etc., subst. them into each composition and determine which output is greatest.
None of these are correct, however of the ones you listed, A would be the most likely to be correct. y is greater than 3... therefore making y a number greater than zero.
Answer: No one will ever know that
Step-by-step explanation:
Seriously even Google doesn’t know it
Answer:
x = -3
(-3,7)
Step-by-step explanation:
y = –3x – 2,
y = 7
We know the value of y, y=7
Substitute into the first equation
7 = –3x – 2
Add 2 to each side
7+2 = –3x – 2+2
9 = -3x
Divide each side by -3
9/-3 = -3x/-3
-3 = x
