When integer x is multiplied by 3, the result is greater than 10 but less than 14?

meriva

The answer is 4. If you multiply x by 3 you get 9 but if you multiply it by 5 you get 15. However, 3*4=12, which is greater than 10 but less than 14.

gulaghasi [49]

Answer:

The correct option is 3.

Step-by-step explanation:

If a line passes through to points $(x_1,y_1)$ and $(y_1,y_2)$ , then the slope of line is

$m=\frac{y_2-y_1}{x_2-x_1}$

Given points are (4,-7) and (6,3).

The slope between given points is

$m=\frac{3-(-7)}{6-4}$

$m=\frac{3+7}{2}$

On further simplification we get

$m=\frac{10}{2}$

$m=5$

Therefore the correct option is 3.

$800 is deposited in an account

Sergeeva-Olga [200]

Answer:

The balance after four years is $1129.27

Step-by-step explanation:

The formula for compound interest, including principal sum, is $A=P(1+\frac{r}{n})^{nt}$

A = the future value of the investment/loan, including interest
P = the principal investment amount (the initial deposit or loan amount)
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per unit t
t = the time the money is invested or borrowed for

∵ $800 is deposited in an account

∴ P = 800

∵ The account pays 9% annual interest

∴ r = 9% = 9 ÷ 100 = 0.09

∵ The interest is compounded annually

∴ n = 1

∵ The time is 4 years

∴ t = 4

- Substitute the values of P, r, n, and t in the formula above

∵ $A=800(1+\frac{0.09}{1})^{(1)(4)}$

∴ $A=800(1.09)^{4}$

∴ A = 1129.265

∴ The balance after four years is $1129.27
