Step-by-step explanation:

exponential growth or decay function is a function that grows or shrinks a a constant percent growth rate. The equation can be written in the form f(x) = a(1 + r)x or f(x) = abx where b = 1 + r.

Answer:

a = 12

x = 5.714

Step-by-step explanation:

sf = 15 / 9

A men's shoe size is related to his foot length and can be modeled by the equations s=1.7f -7.2, where s is shoe size and fis fo

otez555 [7]

Answer:

B. 8

Step-by-step explanation:

Given the equation, $s = 1.7f - 7.2$ ,

where,

s = shoe size,

f = foot length,

To determine the shoe size of a man that has a foot length (f) of 9 in, substitute f = 9 into the equation.

$s = 1.7f - 7.2$

$s = 1.7(9) - 7.2$ (substitution)

$s = 15.3 - 7.2$

$s = 8.1$

His shoe size is approximately 8 inches

for a school fundraiser troy sold 28 bags of popcorn and 40 candy bars and made $282. Jake sold 17 bags of popcorn and 20 candy

nevsk [136]

Answer:

$6.50 per bag of popcorn

Step-by-step explanation:

let a bag of popcorn be represented by p and a candy bar be b

28p + 40b = $282

17p + 20b = $160.50

this is an example of simultaneous equations

so you have to double the second equation to give 34p + 40b = $321

subtract the equations to give one -- > 6p = $39

divide $39 by 6 to give the value of one bag of popcorn = $6.50
