Calculate it up and it shall be the anwser
2(-1)-4(-3)
-2-(-12)
-2+12=10
(-1)2+(-3)
1-3=-2
Let "x" be the positive integer
Twenty times a square of a positive integer plus 50:
20x² + 50
Negative 40 times the square of the positive integer plus one-hundred and ten times the positive integer:
-40x² + 100x
The equation could be used is shown below:
20x² + 50 = -40x² +100x
20x² + 40x² -100x + 50 = 0
60x² - 100x +50 =0
Answer:
C
Step-by-step explanation:
You read piece wise as
2 turns on at x = -5, then turns off at x = - 1 and so on
