B
B
A reflection of AB across the z-axis followed by a translation 4 units to the right
C A reflection of AB across the y-axis followed by a reflection across the x-axis followed by a translation 2 units down
D
A reflection of AB across the y-axis followed by a translation 2 units to the left followed by a translation 6 units down
E
A translation of AB 6 units to the right followed by a translation 6 units down

24 units

step-by-step explanation:

6/20

step-by-step explanation:

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
