Step-by-step explanation:
Answer:
option c
Step-by-step explanation:
(4 - 2i) + (12 + 7i)
multiply the brackets first
4 - 2i + 12 + 7i
combine like terms
16 + 5i
For this case we have the following expression:
Let's evaluate the expression for some values of x.
We have then:
For x = 1:
For x = 2:
For x = 3:
For x = 4:
For x = 5:
Answer:
The value of the expression in ordered pairs is:
- (1,8)
- (2.6)
- (3,4)
- (4.2)
- (5.0)
First we need to convert yard to miles
3520yards÷1760yards/mile=2 miles
From there we know:
Alex walked 1 mile for 15 mins and Sally walked 2mile in 24 mins
We need to convert these mileages to miles per hour
1mile/15mins*60mins/hour=4miles /hour
2mile/24mins*60mins/hour=5miles per hour
Alex walks at 4 miles per hour and Sally at 5 miles per hour
Sally walks 1 mile per hour faster than Alex
N would = 20, because 2x20=40 which is greater than 30
