Answer:
line of reflection was across the -2 line on the x-axis
Step-by-step explanation:
the y points on all of the given points are the same distance from each other to the -2 line. (ie. (-5,2) and (-5,-6) = the 2 is 4 places away from -2 and -6 is 4 places away from -2.) making the reflection point -2 because it is the halfway point for all y values. It is on the x-axis because it is said it is a horizontal line. If it was vertical it would be on the y-axis.
Plug -6 in for x and solve.
y = (-1/3)(-6) + 5
y = 2 + 5
y = 7

%
Step-by-step explanation:
The probability of having a boy or girl is 
A couple plans to have 6 children
Probability of having at least one male child

On solving the above term, we get -

The probability for the couple to be very confident that they will get at least one boy in 6 children is

Answer:
2 × 2 × 2 × 5
Step-by-step explanation:
2 × 2 =4×2 =8×5=40
30
1 x 30
1 x (15 x 2)
1 x (3 x 5 x 2)
so ur answer is 1 x 3 x 5 x 2...which are all prime numbers
