- √ (1/121)
You can break up the square root of a fraction like this: √(1/121) = √1 / √121 .
At this point, it helps if you know that 121=11x11, or √121 = 11.
So, the original expression is
- ( √1 / √121 ) = <u>- ( 1 / 11 ) </u> and there you are.
Answer:
5x-2y=3
-3x+4y=1
5x-2y=-3x+4y+2
+2y
5x=-3x+6y+2
+3x
8x=6y+2
divide by 2
4x=3y+1
-3y+4x=1
wait so that means that -3x+4y=-3y+4x so that means that both x and y are equal so lets just say their the same
-3x+4x=1
x=1
y=1
Hope This Helps!!!
Answer:
B) f(x) ≥ 3x + 4; g(x) ≤ -1/2x - 5
Step-by-step explanation:
Point B is above (≥) the boundary line for f(x) and below (≤) the boundary line for g(x). So, it satisfies the inequalities ...
f(x) ≥ (3x+4)
g(x) ≤ (-1/2x -5)
Answer:
Yes. In base 4 numbers if a number ends with 0 or 2 then it is an even number. If it ends with 1 or 3 then it is an odd number.
Step-by-step explanation:
The first 13 numbers in base 4 are written in brackets next to their corrsponding decimal number below
decimal number 0(0) ,1 (1) ,2(2), 3(3), 4(10), 5(11), 6(12), 7(13), 8,(20), 9(21), 10(22), 11(23), 12(30), 13(31) and so on
From above we can deduce that in base-4 any number ending with 0 or 2 is an even nmuber and any number ending with 1 or 3 is an odd number
