235/100=2.35 (I didnt know if you wanted the answer so i just put it down)
(divided)
Answer:
Answer is the 2nd one.
Step-by-step explanation:
Answer:
A.) x / 3 = 12 ----> x = 12(3) ----><em> </em><em>x = 36</em>
B.) 2x + 3 = 20 ----> 2x = 17 ----> x = 17/2
C.) 4/3x = 10/3 ----> x = 10/3 x 3/4 ----> x = 30/12 = 5/2
D.) -4x = -24 ----> x = -24/-4 ----> x = 6
E.) 2(x-4) = 10 ----> 2x - 8 = 10 ----> 2x = 18 ----> x = 9
F.) -0.5x + 1.1 = -2.9 ----> -0.5x = -4 ---> x = -4 / -0.5 ----> x = 8
0.09 is 10 times as much as 0.009, since it is one decimal place behind 0.09!
Hope I was able to help, if you need any more help, please let me know.
Answer:
hello :
Step-by-step explanation:
f(x)=|x²-x-2|
f(x) = x²-x-2 if : x²-x-2 ≥ 0
f(x) = - (x²-x-2) if : x²-x-2 ≤ 0
x²-x-2 = ( x+1)(x-2)
sign of : x²-x-2 is :
x²-x-2 ≥ 0 : x≤ -1 or x ≥ 2
x²-x-2 ≤ 0 : -1 ≤ x ≤ 2
