Given (x – 7)2 = 36, whats the values of x
nata0808 [166]
<span>x = 25
(x – 7)2 = 36
(x*2) - (7*2) = 36 : multiply x*2 and 7*2 because of distributive property 
2x - 14 = 36 : multiply
2x = 36 + 14 : add 14 to combine like terms 
2x = 50 : add
x = 50/2 : divide 50 by 2 to get x alone
x = 25 : simplify </span>

You withdraw 260$ from your bank account in 5 trips to the ATM. what is the average change in your account balance for each trip
N76 [4]
To find the average over 5 times, we have to divide the total by 5. Therefore, 260/5 = 52 = the average change in your account balance each trips. 260 = amount of money you withdraw, 5 = number of trips made by the ATM. We need to divide due to that if something is spread out equally 5 times, what you get in one time clearly won't be all of it

In 1985, there were 285 cell phone subscribers in the small town of Glenwood. The number of subscribers increased by 75% per yea
Allisa [31]

Answer:

4676.85 cell phone subscribers were in Glenwood in 1990 .

Step-by-step explanation:

As the exponential increase function is denoted by.

y = a (1 + r)^{t}

Where a is the initial value , r is the rate of interest in the decimal form and t is time.

As given

In 1985, there were 285 cell phone subscribers in the small town of Glenwood.

The number of subscribers increased by 75% per year after 1985.

75% is written in the decimal form

= \frac{75}{100}

= 0.75

a = 285

r = 0.75

As the year changes from 1985 to 1990 .

t = 1990 - 1985

t = 5

Put in the expontential increase function.

y = 285 (1 + 0.75)^{5}

y = 285 (1.75)^{5}

y = 285 × 16.41

y = 4676.85

Therefore 4676.85 cell phone subscribers were in Glenwood in 1990 .
