You are given three points. Each point consists of an abscissa (x-value) and an ordinate (y-value). One by one, take the abscissas and insert them into the given formula to produce a y value. Then, compare this calculated y-value to the ordinate given.
Example: Determine whether (2,0) lies on the graph of the given line.
Subst. 2 for x: y = (9/5)(2-273) + 32 = -455.8. This is not equal to the given ordinate (0), so NO, (2,0) does NOT lie on the graph of the given function.
Answer:
$39
Step-by-step explanation:
60 percent of 65 dollars is 0.6 * 65 which is $39
40 players multiplied by 30 teams = 1,200 players in the MLB
53 players multiplied by 32 teams = 1,696 players in the NFL.
1,696 - 1,200 = 496
There are 496 more players in the NFL then in the MLB.
To solve this problem, you just need to add the two functions together, making sure that you watch your signs.
f(x) + g(x) = (2x - 7) + (-6x -3)
After we simplify and combine like terms, we get:
f(x) + g(x) = 2x - 7 - 6x - 3
= -4x - 10
The domain is all real numbers because both of the functions being added together also have a domain of all real numbers.
Therefore, the answer you have selected (the last option) is correct.
Hope this helps!
