Svetach [21]2 years ago

Answer:

Kimberly and Mike had at first $100 each

Step-by-step explanation:

Assume that Kimberly and Mike each have $x

∵ Kimberly has $x

∵ Kimberly spent $50

- Find the reminder with Kimberly by subtracting 50 from x

∴ The money left with Kimberly = x - 50

∵ Mike has $x

∵ Mike spent $25

- Find the reminder with Mike by subtracting 25 from x

∴ The money left with Mike = x - 25

∵ Mike's money is 50% more than Kimberly's money

- That means Mike's money is more than Kimberly's money by

  50% of Kimberly's money

∴ x - 25 = (x - 50) + 50%(x - 50)

∵ 50% =  = 0.5

∴ x - 25 = (x - 50) + 0.5(x - 50)

- Simplify the right hand side

∴ x - 25 = x - 50 + 0.5x - 25

- Add the like terms in the right hand side

∴ x - 25 = 1.5x - 75

- Add 75 to both sides

∴ x + 50 = 1.5x

- Subtract x from both sides

∴ 50 = 0.5x

- Divide both sides by 0.5

∴ 100 = x

∵ x represents the amount of money that Kimberly and

  Mike each had at first

∴ Kimberly and Mike had at first $100 each

Write the equation of the line that passes through (0, 3) and is parallel to the line 3x + 5y = 6.
Sunny_sXe [5.5K]
There's more ways than one to solve this, just as there's more ways than one to skin a cat.

Two paralle lines have the same slope, so the desired new line looks exactly like the given line 3x + 5y = 6, except that the constant, 6, is replaced by another value.

Write out 3x + 5y = c
Replace x with 0 and y with 3.  Then 3(0) + 5(3) = c, and c = 15.

Thus, the equation of the new, parallel, line is 3x + 5y = 15.

The population of bacteria can be modeled by the function below, where t represents the time since the population started decayi
Oksana_A [137]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete. I will assume the function is:

f(t) = 15(0.86)^t

Required

Determine the rate of decay

In an exponential function f(x) = ab^x,

The decay rate of the function is calculated as:

1 - r = b

By comparison:

b = 0.86

So, the equation becomes:

1 - r = 0.86

Make r the subject

r = 1 - 0.86

r = 0.14

<em>The rate of decay is 0.14</em>
