A non example of a sequence would be: +1 +2 +3.
Hi! Since prime numbers only have 1 and themselves as factors, 101 would be prime. 123 has factors of 1,3,41,123, so it would classify as a composite number. I hope this helps!:)
Answer:
y=0.5x+3
Step-by-step explanation:
Divide both sides by 2 which will give you y=0.5x+3.
Answer:
b) −3y2−2x+1
d) −4xy+4y2−y−10
Step-by-step explanation:
b) -4x <u>+ y2</u> <em>- 9</em> <em>+ 10</em> - x + 3x<u> - 4y2</u>
<u>(i have just underlined, italic and made it bold to show the like terms)</u>
-4x - x + 3x = -2x
y2 - 4y2 = -3y2
-9 + 10 = 1
-2x - 3y2 + 1
d) 0 - 20 <u>- 5xy</u> + 4y2 + 10 - y <u>+ xy</u>
<u>(i have just underlined, italic and made it bold to show the like terms, however the '-y' and '4y2' have no like terms)</u>
0 - 20 + 10 = - 10
-5xy + xy = - 4xy
-10-4xy+4y2-y
Answer:
x = 2 ; y = 3
Step-by-step explanation:
3x = 6
x = 2
4y = 12
y = 3
