The last one represents a function ..
Answer:
( cos40° + isin40°)
Step-by-step explanation:
To divide
= 
[ cos(x₁ - x₂) + isin(x₁ - x₂)
Given
= 
( cos(90 - 50)° + isin(90 - 50)°
= ( cos40° + isin40° )
Answer:
x=lizards y=snakes
x+36=y x+y=214
x + x +36=214
2x=214-36
2x/2=178/2
x=89lizards y=89+36=125snakes
Step-by-step explanation:
f= female sankes m=male snakes
m+31=f
m+f=125
m+m+31=125
2m=125-31
2m/2=94/2
m=47 male snakes
f=47+31=78female snakes
Answer:
x = 675
Step-by-step explanation:
Collect terms and solve the resulting 2-step linear equation.
(x-355)+(x)+(80+2x)=2425 . . . . . given
4x -275 = 2425 . . . simplify
4x = 2700 . . . . . . . add 275
x = 675 . . . . . . . . . divide by 4
There is no difference, both equal 40.
