|a| = b gives
a =b or a = -b
so,
|-x| = -10
gives
-x = -10 or -x = 10
x = 10, -10
now let us verify,
when x = 10, |-10| = +10 and it is not = -10
so, x= 10 is NOT a solution.
when x = -10, |-(-10)| = |10| = 10 and it is not = -10
so, x= -10 is NOT a solution.
hence, this equation does not have a solution.
If we know that |...| can never be negative, we can directly deduce that this equation does not have any solution.
Answer:
B) 0.60n+1.48n = 176.80
Step-by-step explanation:
0.60 for every spiral wire per book = 0.60*n
0.74 per chipboard cover, 2 needed for each book = 1.48 per book = 1.48*n
Put it together: 0.60n+1.48n = 176.80
<span>The exact solution of cos (17</span>π<span>/6) is as follows:
First change the angle into degrees.
17(</span>π/6) (180°/π) = 510°
Then we calculate the cosine of the angle above and it as follows:
cos 510° = -(√3)/2
Hope this answers the question. Have a nice day.
What does "gcf" stand for?
Where is the graph? But I guess the one that looks linear?
