200=398j
The 398 times j would just be 398j
is usually means equals
The answer to 17 is 18.6 and the 6 is repeating
Answer:
160 miles
Step-by-step explanation:
200 * 0.8 is 160
Domain is all the possible inputs of an equation. In this example, the only concern is the x + 5 because the denominator cannot equal 0 because we can't divided by 0. So we set x + 5 equal to zero and solve for x.
x + 5 = 0
x = -5
The restriction is that x cannot equal -5.
2(x - 5) = 110
2x - 10 = 110
Add 10 to both sides.
2x = 120
Divide by 2 on both sides.
x = 60
