Hello :
<span>sin 2x = sin x and 0 ≤ x ≤ 2π. .....51°
note : sina = sinb equivaut : (a = b +2k</span>π) or ( a = π - b +2kπ) .... k∈ Z
(1) equiv : ( 2x = x +2kπ) or (2x = π - x +2kπ)
( x = 2kπ) or ( x = π/3 + 2kπ/3)....(general solution )
but : 0 ≤ x ≤ 2π
k = 0 : x = 0 , x = π/3
k= 1 : x = 2π , x = π
k = 2 ; x = 5π/3
How will you sell 9 and 10
Step-by-step explanation:
Answer:
y=3x-13
Step-by-step explanation:
1) find slope
5--1/8-4=6/2=3
2) (y--1)=3(x-4)
y+1=3x-12
y=3x-13
