3^(-4) means "one over 3^4"

1/(3^4)

That's equal to

1/81

and

(1/3)^4

This is also equal to 3^2/3^6.

So four of those are correct.

|z - 1| = 7z - 13 solve this equation and check for extraneous solutions

Tema [17]

$|z - 1| = 7z - 13$
either:
$z - 1 = 7z - 13$
and in that case:
$- 1 + 13 = 7z - z$
$12 = 6z$
$z = 12 \div 6 = 2$
or:
$z - 1 = - 7z + 13$
and in that case
$z + 7z = 13 + 1$
$8z = 14$
$z = 14 \times 8 = 1.75$
So; the answer is: either 2 or 1.75

Answer:

140°

Step-by-step explanation:

Angles 1 and 3 are "corresponding" angles, so are congruent.

∠1 = ∠3

20x +60 = 30x +20

40 = 10x . . . . . . . . . . . . subtract 20x+20

4 = x . . . . . . . . . . . . . . divide by 10

∠1 = 20x +60 = 20(4) +60 = 80 +60

∠1 = 140°
