5 0

Answer:

x = 1

Step-by-step explanation:

{5}^{2x}  - 2( {5}^{x} ) - 15 = 0

( {5}^{x}  {)}^{2}  - 2 \times  {5}^{x}  - 15 = 0

{t}^{2}  - 2t - 15 = 0

{5}^{x} t =  - 3 \:  \: .5

{5}^{x}  = 5

x = 1

Answer:

A. yes, the data represents a function because u have no repeating x values. A function cannot have repeating x values...they can have repeating y values, just not the x ones

Step-by-step explanation:

B. table : (8,8)(12,12)(14,16)(16,16)

               look at ur points...when x = 8, y = 8...so the table, when x = 8 has a

               value of 8

relation : f(x) = 8x - 5....when x = 8

             f(8) = 8(8) - 5

             f(8) = 64 - 5

             f(8) = 59....and the relation has a value of 59

Therefore, the relation has a greater value when x = 8 <==

C. f(x) = 8x - 5...when f(x) = 19

    19 = 8x - 5

     19 + 5 = 8x

    24 = 8x

    24/8 = x

    3 = x <==

Tickets for a county fair are $8 for an adult and $5 for a child. If you have a 15% discount card, how
FrozenT [24]

Answer:

$21.25

Step-by-step explanation:

The cost of the 2 adult tickets before the discount is $8 * 2 = $16

The cost of the 2 child tickets before the discount is $5 * 2 = $10

The total cost before the discount is $16 + $10 = $26

The total cost after the discount is

$26 * (1 - 0.15) =

$26 * 0.85 =

$21.25
