Answer:
C. -1 9/10, -1/2, 0.4, 3/5
Step-by-step explanation:
Using a number line, we can see that negative numbers are to the left of '0' and positive numbers are to the right of '0'. To compare numbers for increasing order, we would start with the lowest number to the farthest left on the number line to the greatest number to the farthest right. Placing the following numbers on the number line, the furthest to the left is -1 9/10, then -1/2, followed by 0.4 and then the greatest, 3/5. You can also compare by converting them all into decimals:
-1 9/10 = -1.9
-1/2 = -0.5
0.4 = 0.4
3/5 = 0.6
You first have to divide 42 by 2 and you get 21. Then subtract 21-4 and you get 17. Then add the other half which is the other 21 by 4 and you get 25. 17+25=42 Rob has 17 DVD and Carly has 25 DVD.

Answer:
x=435 ,y=145
Step-by-step explanation:
You substitute x for 3y in this equation and get
3y+y=580
from here you simplify
4y=580
and divide 580 by 4 to get what y is
y=580/4
y=145
now since x=3y you mutiply y by 3
x=3(y)
x=3(145)
x=435
D) 2g² + 5g + 4 is the polynomial that is factored completely.
This is because the terms in the polynomial do not have any common factors.
a) g⁵ - g can be factored into g(g⁴ - 1)
b) 4g³ + 18g² + 20g can be factored into 2g(2g² + 9g + 10)
c) 24g² - 6g⁴ cab be factored into 6g²(4-g²)
