Assignment I. If 9^1-x= 27 and x-y = -1½ find the value of x+y.

2.2^1-y x 2^y-1 / 2^y+2= 8^2+3y . find y.

3. If 2^x+y= 16 and 4^x-y= 1/32 Find x and y.

4.Solve 1 / 81^<x-2> =27<1-x>

5.Solve the equ 9^2x-3 / 3^x+3 = 1
6. Simplify 1/3^5x x 9^n-1 x 27^n-1

7. If 9^<2-x> = 3. Find x.

8.If 27^x =9y. Find the value of x/y.

9. If 2^n=12^d find the value of (2^n-1) (5^n-2)

10.If 9^2x = ⅓ (27^x). Find n.

Click on the y intercept. -x +4 i know you cant click on it so could you just say the coordinates like (example - (1,0) you so much.

Ab based on the given diagram, if m_1 = 60° then m 2 = 30 60 90 180
