If your original equation was 
, then a reflection over the x-axis means you need all the y-values to switch sign. This means you need to multiply that function by -1.
or 
Answer:
-1 1/2
Step-by-step explanation:
-(3-6b)=6b + 5 .remember to balance!!!!
-6b + 6b= 6b + 6b
-3=12b+5
-3+5=5-5
-8=12b now divide since its the inverse operation
think 12/-8= -1 1/2
so B equals - 1 1/2
B, 8 to 11 because general number of marbles is 8+3=11 and only 8 of all are white)
Answer:
5 cm
Step-by-step explanation:
Here, we want to get the length of each box edge
Let the length be s
Mathematically, the volume of a cube is s^3
Thus;
s^3 = 125
s^3 = 5^3
s = 5 cm
Answer:
P (black marble) =3/11
Step-by-step explanation:
We need to find the total number of marbles
4 black marbles+ 2 red marbles+ 6 white marbles= 12 marbles
We take away a black marble and throw it away
3 black marbles+ 2 red marbles+ 6 white marbles= 11 marbles
The probability of drawing a black marble is
P (black marble) = black/total
=3/11
