Answer:
Assuming your equations are:
x-3y=3
4x+3y=-3
The answers are x = 0 and y = -1.

See the image for the graph.
Okay, here goes. Notice that since the line of reflection was the x-axis, the x-coordinate of each vertex stays the same and the y-coordinate of each vertex is the opposite of the original vertex, so in that case the answer is 4 or D.
Answer: 2.28%
Step-by-step explanation:
Given: An airport find that at the present time, the mean noise level is 103 decibels and the standard deviation is 5.4 decibels.
The distribution of noise levels(x) for all jets during takeoff over the neighborhood has a normal distribution.
The probability that jets have a noise level less than 92.2 decibels when taking off over this neighborhood will be :-

Hence, the percent of these jets have a noise level less than 92.2 decibels when taking off over this neighborhood = 2.28%
The answer is triangle ACD is congruent to triangle ABD.
Answer:
Step-by-step explanation:
<u>Given:</u>
<u>Length is:</u>
<u>Substitute values and solve for w:</u>
- 500 = 2*120 + 2w
- 2w = 500 - 240
- 2w = 260
- w = 260/2
- w = 130 m
