Answer:
f(x) + g(x) = -2x^2 - 2x + 8
Step-by-step explanation:
Given: f(x) = 3x+5 and g(x) = -2x^2-5x+3
Find f(x) + g(x)
f(x) + g(x) = 3x + 5 + (-2x^2 - 5x + 3)
f(x) + g(x) = 5 + -2x^2 - 2x + 3
f(x) + g(x) = -2x^2 - 2x + 8
The answer is D, 5.29, due to Pythagoras's theorum
Answer:
Sally ends at 3 feet below zero point.
Step-by-step explanation:
Let be 
the height with respect to zero point, which is represented by the following sum:
Where:
- i-th travelled height, measured in feet.
In addition, positive sign means ascension, whereas negative sign means descent.
The statement can be translated into the following mathematical identity:
Sally ends at 3 feet below zero point.
Random samples can provide more information on a population of people or things.
Hope I could be of help :)
The fact that they are multiples of each other makes it easy.
11 goes into 55 5 times, right?
So
The ratio is 5:1
