Answer:
Step-by-step explanation:
Y = - 3x. Equation 1
x + y = - 4 equation 2
Putting value of y
x + (-3x) = - 4
x - 3x = - 4
-2x = - 4
x = - 4/-2 = 2
Putting value of x in the equation 1
Y = - 3(2)
Y = - 6

Answer:
1 5/6
Step-by-step explanation:
7x or just x
Both of them are terms when they have a variable next to it
Answer:
see explanation
Step-by-step explanation:
Using 
= i, then i² = ( )² = - 1
and i³ = i² × i = - 1 × i = - i
also
= i² × i² = - 1 × - 1 = 1
We can surmise that i raised to any multiple of 4 will equal 1
Given
( note 35 = 32 + 3 and 32 is a multiple of 4 ), thus
= 
= 1 × i³ = - i
