Answer:
Given any initial point (x, y), a reflection across the y-axis means the y-coordinate remains the same but the sign of the x-coordinate changes. Therefore, the coordinate expression that gives the coordinates of the point after a reflection across the y-axis is (-x, y).

Answer:
76.4%
Step-by-step explanation:
Total area of flag:
LW = (37)(28) = 1036
Total area of red:
LW = (12 + 21)(12 + 12) = (33)(24) = 792
Percent of red:
792/1036 * 100% = 76.4%

Step-by-step explanation:
If A and B are two different events then, P(A U B) = P(A) + P(B) - P(A ∩ B)
Explanation of the formula:
If you look at the Venn Diagram, if you add 2 areas : P(A) and P(B), P(A ∩ B) is overlapping. This is why you should remove P(A ∩ B).
However, in this case, we should find P(A ∩ B) and all the other values are given in the question. Hence, we implement them and find P(A ∩ B).
Tan(angle of elevation) = height / distance from base
so tan(29.5) = 305 / distance from base
distance from base = 305/tan(29.5)
= 539.09 = 539 feet
4(x + 2) = 48
4x + 8 = 48 |subtract 8 from both sides
4x = 40 |divide both sides by 4
x = 10
