What are the real or imaginary solutions of 2x+7X? = 15x7
A. 0, , -5
B. 0,-1,5
C. 15
D. 0, -3,5

x=0  x=(3/5)^1/6

Step-by-step explanation:

2x+7X? = 15x7

Combine like terms

9x = 15 x^7

Subtract 9x from each side

9x-9x = 15x^7 -9x

0 = 15x^7 -9x

Factor out 3x

0 =3x(5x^6 -3)

Using the zero product property

3x= 0   5x^6 -3 =0

x=0      5x^6 =3

              x^6 = 3/5

             Take the sixth root

             x = (3/5)^1/6

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

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