The rule of reflection in the image shown is: (x, -y).
<h3>What is Reflection?</h3>
Reflection is a transformation which creates a new image by flipping over a line of reflection. The new image is congruent to the original image after reflection. The rule of reflection over an x-axis is given as, (x, -y).
In the image given we can see that rotating triangle LMN over the x-axis gave us:
M(-5, 4) → M'(-5, -4)
L(-4, 2) → L'(-4, -2)
N(-2, 3) → N'(-2, -3)
Therefore, the rule of reflection is: (x, -y).

Answer:
After 17 hours there will be about 143 bacteria.
Step-by-step explanation:
Given that in a lab experiment, 80 bacteria are placed in a petri dish, and the conditions are such that the number of bacteria is able to double every 19 hours, to determine how many bacteria would there be after 17 hours, to the nearest whole number, the following calculation must be performed:
80 x ((2/19) x 17) = X
80 x (0.1052 x 17) = X
80 x 1.7894 = X
143.15 = X
Thus, after 17 hours there will be about 143 bacteria.
