Line g is dilated by a scale factor of 2 from the origin to create line g'. Where are points E and F located after dilation, and how are lines g and g' related? F g E -5 -2 -1 The locations of E' and F' are E' (-8, 0) and F'(0,4), and lines g and g'are parallel. The locations of E' and Flare E' (-4, 0) and F'(0, 2), and lines g and g are the same line. O The locations of E' and Fare E' (-2, 0) and F'(0, 1), and lines g and g intersect at point F. The locations of E' and Fare E' (-1, 0) and F'(0, 0), and lines g and g' are not related.

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
