Answer:
19x−47
Step-by-step explanation:
19x+−25+21+−43
You gotta combine the like terms
(19x)+(−25+21+−43)
19x+−47
Answer:
(x + c) (x - c)
Step-by-step explanation:
For any number the polynomial 
can be factored as (x + c) (x - c)
ANSWER
I. The GCF of 6 and 16 is 3. FALSE
II. The LCM of 6 and 16 is 48. TRUE
III. 6 and 16 are both composite numbers. TRUE.
EXPLANATION
The GCF of 6 and 16 is not 3.
It is rather 2.
Factors of 6: {1,2,3,6}
Factors of 16:{1,2,4,8,16}
3 is not even a factor of 16.
The LCM of 6 and 16 is 48. This statement is true.
Composite numbers have more than 2 factors.
6 and 16 are both composite numbers.
Answer:
5. r(x) is f(x) translated down 16 units
7. g(x) is f(x) vertically scaled by a factor of 2/5
Step-by-step explanation:
5. Adding a number to a function value translates that value up by the amount of the number. If the number is negative, the translation is downward. Adding -16 to x^2 translates the graph down 16 units.
___
7. Multiplying a function value vertically scales the graph of the function by the multiplying factor. For factors greater than 1, the result is a vertical expansion; for factors less than 1, the result is vertical compression. Here, the function f(x) = x^2 is multiplied by 2/5, so the resulting g(x) is vertically scaled by a factor of 2/5 (compressed).
For a parabola, the effect is to make the graph appear "wider." Values some distance from the line of symmetry that would have been vertically off the page now appear on the page. Hence, the horizontal extent of the graph on the page has increased.
