To simplify the equation 3(5 + 2x), the distributive factor must be used, so the number outside the bracket (3), must be distributed (or multiplied) with each of the terms inside the brackets (5 and 2x) and then simplify

</span>3(5) + 3(2x)
15 + 6x

The initial value of a stock is $2500. The value of the stock is expected to grow at an annual rate of 4%. Let x represent the n
vekshin1

Answer:

y = ($2500)(1.04)^x

Step-by-step explanation:

The initial value = $2500

The value of the stock is expected to grow at the rate of 4%

Let x represent the number of years since the stock was made available for purchase.

Let y represent the value of the stock x years later.

y1 = amount of money after one year.

y1 = $2500 (100% + 4%)

y1 = $2500 (104%)

y1 = $2500(1.04)

y2 = amount of money after two years

y2 = y1 (100% + 4%)

y2 = y1 (104%)

y2 = y1(1.04)

y2 = $2500(1.04)(1.04)

y2 = $2500(1.04)^2

This will give a pattern

y5 = $2500(1.04)^5

After x years the model of the equation will be y = ($2500)(1.04)^x

There are two different clocks in Wendy's house, one is 20 minutes faster in a day, and the other is 30 minutes slower in a day.
Annette [7]

Answer:

The answer is below

Step-by-step explanation:

For the first clock that is 20 minutes faster in a day, that means it is \frac{20\ min}{60\ min/hr}=\frac{1}{3}hr faster every day. For it to show the correct time, the clock should be 24 hours faster.

Since 1 day = 1/3 hr faster

x days = 24 hr faster

Let x number of days be required to be 24 hr faster. To find x we use the formula:

x=\frac{24 \ hr* 1\ day}{\frac{1}{3}hr }  \\x=72\ days

For the second clock that is 30 minutes slower in a day, that means it is \frac{30\ min}{60\ min/hr}=\frac{1}{2}hr faster every day. For it to show the correct time, the clock should be 24 hours slower.

Since 1 day = 1/2 hr slower

y days = 24 hr faster

Let x number of days be required to be 24 hr slower. To find x we use the formula:

y=\frac{24 \ hr* 1\ day}{\frac{1}{2}hr }  \\y=48\ days
