Let white marbles = x

Purple marbles = 5x + 2

Given:

x + 5x + 2 = 104

6x = 102

x = 17

Purple marbles = 5(17) + 2 = 85 + 2 = 87

Levart [38]

Answer:

$\tt C) \:\tt f^{-1}(x)=\cfrac{x-6}{3}$

Step-by-step explanation:

We're given,

$\tt f(x) = 3x + 6$

~

$\tt y=3x+6$

$\tt x=3y+6$

$\tt x-6=3y$

$\tt y=\cfrac{x-6}{3}$

$\tt f^{-1}(x)=\cfrac{x-6}{3}$

the points (0,1), (1,5), (2,25), (3,125) are on the graph of a function which equation represent that function

8090 [49]

f(x) = $5^{x}$

note the range is {1, 5, 25, 125 } which can be expressed as

{ $5^{0}$ , $5^{1}$ , $5^{2}$ , $5^{3}$ }

the exponents being the domain { 0, 1, 2, 3 }

thus f(x) = $5^{x}$ an exponential function
