For 3 consecutive odd integers, the result of adding the smallest integer to four times the largest integer is 121. What are the

irakobra [83]

Answer: 21, 23, 25

Step-by-step explanation:

Let the integers be y, y+2 and y+4.

From the question, we are informed that the result of adding the smallest integer to four times the largest integer is 121. This can be mathematically expressed as:

y + 4(y+4) = 121

y + 4y + 16 = 121

5y + 16 = 121

5y = 121-16

5y = 105

y = 105/5

y = 21

Since y = 21,

y + 2 = 21 + 2 = 23

y + 4 = 21 + 4 = 25

The integers are 21,23 and 25

Answer:

y = 3x - 5

Step-by-step explanation:

I used my calculator so that it would be faster.

But if you want work you have to find the slope then plug in.

To find the slope use points (1, -2) and (2, 1) use this formula $\frac{y2 - y1}{x2 - x1}$

Plug the points in $\frac{1 - -2}{2-1} =\frac{3}{1} = 3$

So your slope is 3

NOw Plug In (1, -2)

-2 = 3(1) + b (b represents the y- intercept)

-2 = 3 + b (subtract 3 on both sides)

-5 = b

The final equation is y = 3x - 5

Hope this helps ya!!

Greg deposited $4000 into an account with 4.6% interest, compounded semiannually. Assuming that no withdrawals are made, how muc

Zinaida [17]

The amount in account after 7 years is $ 5499.445

Solution:

The formula for total amount in compound interest is given as:

$A = p(1+\frac{r}{n})^{nt}$

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

Here given that,

A = ?

P = 4000

t = 7 years

$r = 4.6 \% = \frac{4.6}{100} = 0.046$

n = 2 ( since compounded semi annually)

Substituting the values in formula, we get

$A = 4000(1+\frac{0.046}{2})^{2 \times 7}\\\\Simplify\ the\ above\ expression\\\\A = 4000(1+0.023)^{14}\\\\A = 4000(1.023)^{14}\\\\A = 4000 \times 1.37486\\\\A = 5499.445$

Thus amount in account after 7 years is $ 5499.445
