Answer:
3π (540°) and 5π(900°)
Step-by-step explanation:
π radian = 180° degree
in the trigonimitrical cercle each point is taken by many values
so π position is also -π position
to move from π to -π you should move 360° (wich is 2π) backwards
π-2π = π
so -π = π +2π
you can get as much as you can of values similar to π using the formula :
π + 2*k*π where k is a relative number
π+ 2*1*π = 3π
π+2*2*π = 5π
3π is 540°
5π is 900°
<span>-3(2n+1)+7=-5
Multiply the number outside of the parenthesis with the numbers inside the parenthesis
-6n-3+7= -5
Subtract 7 from both sides
-6n-3=-12
Add 3 to both sides
-6n=-9
Divide -6 on both sides

Step-by-step explanation:
Answer:
-2
Step-by-step explanation:
16= -4(x-1)+4
16 - 4 = -4x + 4
12 = -4x + 4
12 - 4 = -4x
8 = -4x
x = 8 ÷ -4
x = -2
