Nutka1998 [239]

Answer:

Step-by-step explanation:

Probability is the ratio of the required outcome to the total possible outcome

Total outcome = 75

Number of times target was hit (expected outcome) = 41

If the triangle on the grid below is translated by using the rule (x, y) right-arrow (x + 5, y minus 2), what will be the coordi
Cloud [144]

Using translation concepts, it is found that the coordinates of the image of point B is given by: (0, –2).

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

In this problem, the rule is given by:

(x,y) -> (x + 5, y - 2).

Hence, the image of point B, given by B', is:

(-5,0) -> (-5 + 5, 0 - 2) -> (0,-2).
