ANSWER

EXPLANATION
The polar form of a complex number ,

is given by:

where

The given complex number is:




And



Hence the polar form is :

The answer is 5. Work backwards: first add 7 to 9, then divide by 2, then subtract 3.
9+7=16
16/2=8
8-3=5
Cross Check:
5+3=8
8*2=16
16-7=9
Final Answer: 5
we have

Group terms that contain the same variable, and move the constant to the opposite side of the equation

Combine like terms

Divide by
both sides


therefore
<u>the answer is</u>
the value of p in the linear equation is 
Alex has 128 baseball cards, Leo has 66 cards, and ginny has 210.
Answer: 195
Step-by-step explanation:
Cost per student = $4
Total number who attended = n
The cost of the total of student who attended will be cost per student multiplied by the total number of students, that is
Total cos = 4n
Since, they are to pay $140 , for publicity, then the total cost becomes
T = 4n - 140
From the last statement
4n - 140 ≥ 640
4n ≥ 640 + 140
4n ≥780
n ≥ 780/4
n ≥ 195
That means at least 195 students must attend if the science club is to earn at least $ 640
