Answer:
x = (-7,7)
Step-by-step explanation:
1.add 5 on both side
2.divide each side of the equation by 2
3.take the square root of each side of the equation to solve for x
Work out length of one second by dividing by 525600, then multiply that answer by 8.333. Answer should be 93026473.1507 miles
Answer:
B. Only (-3,5)
Step-by-step explanation:
1. Plug in the x values from the answer choices and see if it gives you the y-value in the answer choices.
A. y=-3(-2) - 4
= 6 - 4
y = 2
The ordered pair for answer A is (-2,4) where the y-value is 4. Well, when you plugged in -2 for x you got 2, not 4. So A can't be the right answer.
B. y=-3(-3) - 4
= 9- 4
y = 5
The y-value in this ordered pair (-3,5) is indeed 5, so this answer holds true.
Therefore, the answer is B because it is the only ordered pair that has the correct solution.
Answer: 
This is the fraction 2x/15 which can be read as 2x over 15

You can think of it as dividing 14x^2 over 7x and that results in 2x. Then you place that result (2x) over 15 to end up with 2x/15
