Hello:
-1 ≤ sin(x- π ) ≤ 1
-2 ≤ 2 sin(x- π ) ≤2
1-2 ≤ 1+ 2 sin(x- π ) ≤ 1 +2
-1≤y≤3
the range is : <span>[-1 : 3 ]</span>
Hey!
---------------------------------------
Solution:
77.50 = 0.15x + 10
77.50 - 10 + 0.15x + 10 - 10
67.50 = 0.15x
0.15x = 67.50
0.15x/0.15 = 67.50/0.015
x = 450
---------------------------------------
Check:
77.50 = 0.15(450) + 10
77.50 = 67.50 + 10
77.50 = 77.50
---------------------------------------
