Answer:
15+7=22
Step-by-step explanation:
Set up the equations.
Step-by-step explanation:
As shown in the picture, 3(x + 7) = (x + 7) + (2x - 7) + x.
So 3x + 21 = 4x. This means that x = 21.
.88y +.03y = final cost or more simply .91y = final cost
100% - 12% discount leaves 88% of y (.88y)
3% tax = .03y
.88y + .03y = .91y
5 down and 4 left
Long Answer A Vertical shift of 5 units down and a Horizontal Shift of 4 units left.
Cos²(15°) - sin²(15°) = cos(15° * 2) = √(3/2 so this is the answer by using apropriate formula double angle identity
