X equals 4 and the x axis
Answer:
- The inequality should be s<270.
- The number line should be shaded to the left.
Step-by-step explanation:
Miche found that most helicopters fly at speeds of less than 270 kilometers per hour.
If s=speed of the helicopters
Representing this on a number line:
- We have an open circle at 270.
- Everything to the left of the circle is shaded.
Since the options are not given, I would list the mistakes made by Miche.
- The inequality should be s<270.
- The number line should be shaded to the left.
19.99 + 15= 34.99
40-34.99 = 12.51

Recall that i represents the square root of -1, so by squaring it we get -1.
(2 + 4i)(7 - 3i)
= 14 - 6i + 28i + 12
= 26 + 22i
Answer:
x = 7
Step-by-step explanation:
Let x be the number
x+16 = 23
Subtract 16 from each side
x+16-16 =23-16
x = 7
