Answer:
To reflect a point across the vertical line x = -2, we can use the formula:
(x, y) → (2c - x, y)
where c is the x-coordinate of the line of reflection. In this case, c = -2. Let's apply this formula to the point W(-4, -4):
W' = (2(-2) - (-4), -4)
= (-4 + 4, -4)
= (0, -4)
Therefore, after the reflection across x = -2, the coordinates of W(-4, -4) become W'(0, -4).

Answer:
The area after 9 years will be 1,234 km^2
Step-by-step explanation:
In this question, we are tasked with calculating what the area of a certain forest that decreases at a certain percentage would be after some years.
To answer this question, we shall be using an exponential approximation.
Now, to use this exponential approximation, we shall be needing a supporting exponential mathematical equation.
This can be written as;
A = I(1-r)^t
where A is the new area we are looking for
I is the initial area which is 1700 according to the question
r is the rate of decrease which is 3.5% = 3.5/100 = 0.035
t is time which is 9 years according to the question
We plug these values and have the following;
A = 1700(1-0.035)^9
A = 1700(0.965)^9
A = 1,233.66
This is 1,234 km^2 to the nearest square kilometer
ticket sells for $74.50. Bus shuttle prices to the
event cost $15 per family. Which equation can
be used to determine t, the total cost to attend
the game if n tickets are purchased by the
Gonzalez family?
F. n = 74.50t + 15
G. t = 15n+74.50
H. t = 74.50m + 15
J. t = 74.50m + 15n
