10. -0.0161006623
Step-by-step explanation:
Those were the only ones I could help on, sorry I couldn't help on the other ones.
Plug in -8 for x to get 8(-8)+8y=-48. then you have -64+8y=-48. add 64 to the right side of the equation to get 16. now you have 8y=16. divide by 8 to have the variable by itself so y=2.
Answer:
f(x) + g(x) = 2x² - 5x - 8 ⇒ 2nd answer
Step-by-step explanation:
* Lets explain how to solve the problem
- We can add to functions by adding the like terms in them
∵ f(x) = 2x² + 3x - 4
- f(x) is a quadratic function because the greatest power of x is 2
∵ g(x) = -8x - 4
- g(x) is a linear function because the greatest power of x is 1
∵ f(x) + g(x) means (f + g)(x)
∴ f(x) + g(x) = (2x² + 3x - 4) + (-8x - 4)
- Add the like terms
∵ 3x + -8x = -5x
∵ -4 + -4 = -8
∴ f(x) + g(x) = 2x² + -5x + -8
- Remember (+)(-) = (-)
∴ f(x) + g(x) = 2x² - 5x - 8
* f(x) + g(x) = 2x² - 5x - 8
