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
Answer:
$16
Step-by-step explanation:
60 + 4 = 64
64 ÷ 4 = 16
CHECK:
16 x 4 = 64
64 - 4 = 60
157. Because when you multiply 10 times 3.14 times 5 you get 157.
The blank is -6x because -6 + 2 equals -4 min which is on the other side of the equation.
