The real part of given complex number -3 + 9i is -3
<em><u>Solution:</u></em>
We have to find the real part of complex number -3 + 9i
A Complex Number is a combination of real Number and an imaginary Number
<em><u>The general form of complex number is:</u></em>
a + bi
Where "a" and "b" are real numbers and i is the unit imaginary number
The given complex number is:
-3 + 9i
On comparing the above complex number with general form of complex number we get,
Real part = -3
Thus real part of given complex number is -3
In order to solve this you need to do the original price - the sold price and figure the difference.
90-180= <span>£</span>18
therefore making it 20% of a profit sale.
Answer:
y intercept = - 40
Step-by-step explanation:
x 24 36 48
y -8 1 10
y = ax + b
a is the gradient (or slope).
b = y intercept.
a = (48-36) / (10-1) = 12/9
Rewrite to solve for b, which means it starts with b = ...
b = y - 12/9 * x
Substitute one point ( 24 , -8 )
b = -8 - (12/9 * 24)
b = y intercept = - 40
Answer:
x<-5 is the correct answer
Step-by-step explanation:
Since Angle DAE = Angle BCE, lines AD amd BC are parallel (by Z-angles).
This means that Angle ADE = Angle CBE (by Z-angles).
We have 2 congruent angles and 1 congruent side (AD = BC, given).
By ASA congruence, triangles AED and CEB are congruent.
