Answer:
C. -7 < x < 7
Step-by-step explanation:
|2x| is the absolute value of 2x. You can think of it as the positive of a number, or as the distance between a number and 0 on a number line.
So |2x| < 14 means 2x is less than 14 units away from 0.
We can split this into two inequalities.
2x < 14 and 2x > -14
Solving both, we get:
x < 7 and x > -7
-7 < x < 7
Answer:
<h3>ya-z/1+y</h3>
Step-by-step explanation:
Making x the subject of the formula;
y=x+z/a-x
Cross multiply
y(a-x) = x+z
ya - yx = x+z
Collect like terms
x+yx = ya - z
x(1+y) = ya - z
x = ya-z/1+y
Hence the value of x is ya-z/1+y
According to the graph, the displacement goes from a maximum position of 14 at time 0.75 to a minimum of -14 at time 2.25 s, hence the maximum displacement is:
14 + 14 = 28 units
14 positive side, 14 negative side.
Answer:

Answer:
B = 45°
BC = 14 km
AB = 14√2 km ≈ 19.80 km
Step-by-step explanation:
If one acute angle (A) of a right triangle is 45°, then the other one is also:
... 180° -90° -45° = 45°
The sides opposite these congruent angles are the same length, 14 km in this case, and the hypotenuse is found from the Pythagorean theorem to be √2 times either leg length.
... AB² = AC² +BC²
... AB = √(AC² +BC²) = (14 km)√(1² +1²) = 14√2 km
