Solve the exponential equation.

27x = 9

3/2
1/3
2/3

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

secant-secant formula:

(whole secant) x (external part) =           (whole secant) x (external part)

(8+y-2) *8=                                           (y+4+6) *6

(y+6)*8 = (y+10) *6

distribute

8y+48 = 6y +60

subtract 6y from each side

2y +48 = 60

subtract 48 from each side

2y = 12

divide by 2

y = 6

sv =     (y+4+6)

sv   = 6+4+6

sv = 16

answer is  

a.

93.98 sq. in.

hope you got it chief

c ) y = 2.5 x - 26.25
