Y= 2x-3
the slope of the line is 2, and b, the y-intercept, is -3
When finding the mean you should first add up all the numbers which are 12,2,8,6 and 57 which will give you a sum of 85 next you should divide your sum by how many numbers there are which is 5 and your answer should be 17
The term that best describes the given statement above is the third option which is negation. In geometry, a negation statement is the opposite of a given mathematical statement. If a statement is true, then its negation is false. And if a statement is false, then its negation is true. The given statement above is false, therefore, it is a negation of the true statement.
Answer:
x^2 +2x -5
Step-by-step explanation:
f(x) = 2x+3
g(x) = x^2 -8
f(x)+g(x) = 2x+3+ x^2 -8
Combine like terms
= x^2 +2x -5
