Answer:
(-5, 18)
Step-by-step explanation:
7x + 2(3 − 3x) = 1 simplifies to
7x + 6 - 6x = 1, which, in turn, simplifies to:
x = -5
Using y = 3 - 3x (see Step 1), we find that y = 3 - 3(-5) = 3 + 15 = 18.
Thus, the solution is (-5, 18).
(f-g)(x) is x² - 3x - 7
Step-by-step explanation:
- Step 1: Given details are f(x) = 3x + 1, g(x) = x² - 6
- Step 2: Calculate (f-g)(x) by using the formula (f-g)(x) = f(x) - g(x)
⇒ (f-g)(x) = (3x + 1) - (x² - 6)
⇒ (f-g)(x) = -x² + 3x + 1 + 6
⇒ (f-g)(x) = x² - 3x - 7
Answer:
c. -2
Step-by-step explanation:
because the linear line goes down we know it is negative
and its not 1/2 because it is rise over run. it runs 1 and rises 2 (or drops 2 because it is negative)
rise over run = -2/1 = -2
Hello.
We simply add f(x) and g(x) together.
1). (x² -3x+5) + (2x² -4x-11)
2). x² -3x + 5 + 2x² -4x-11
3). 3x²-7x-6
Hope that helped.
