It took the plane 1700 seconds for the plane to land. If you look at the x-axis, you can see that the x-intercept crosses through the point (0, 1700).
You have to turn the denominators the same then whatever you do to the top you do to the bottom the just subtract
2x+6 = 20
take 6 from both sides
2x = 14
divide by 2 on both sides
x = 7
Answer:
BC is 25 units
Step-by-step explanation:
AB = AC
4x + 4 = 6x - 14
4x + 4 - 4x + 14 = 6x - 14 - 4x + 14
18 / 2 = 2x / 2
9 = x
2(9) + 7
18 + 7
25
Answer: BC is 25 units
