Answer:

The interest rate of Jess's account was 7%

Step-by-step explanation:

____________________________________

A = P × (1 + rt)

A = final amount

P = initial principal balance

r = annual interest rate

t = time (in years)

___________________________________

A=8,150

P=5,000

8,150 = 5,000 × (1 + r × 9)

8,150÷5,000 = 1 + 9r

1.63 = 1 + 9r

1.63 - 1 = 9r

0.63 = 9r

r = 063÷9

r = 0.07 = 7%

Answer:

The interest rate of Jess's account was 7%

Step-by-step explanation:

A = P * (1 + rt)

A = final amount

P = initial principal balance

r = annual interest rate

t = time (in years)

Replacing with the values we know:

A =  P * (1 + rt)

8,150 = 5,000 * (1 + r * 9)

8,150/5,000 = 1 + 9r

1.63 = 1 + 9r

1.63 - 1 = 9r

0.63 = 9r

r = 063/9

r = 0.07 = 7%

The interest rate of Jess's account was 7%

= 9/4 + 3 + 3

= 9/4 + 6

= 33/4

Write the equation of the line, given the y and x-intercepts:
kolezko [41]

Answer:

The answer to your question is:                161x + 17y - 391 = 0

Step-by-step explanation:

Data

y-intercept = 23         Get the points      (0, 23)

x- intercept = 4.75                                   (4.75, 0)

                      4.75 = 17/4                         (17/4, 0)

slope

              m = (y2 - y1) / (x2 - x1)

              m = (0 - 23) / (17/4 - 0)

              m = -23 / 17/4

             m = - 161 / 17

equation

              (y - y1) = m (x - x1)

              ( y - 23) = -161 / 17 (x - 0)

               y - 23 = -161/17 x

              17(y - 23) = -161x

              17y - 391 = -161x

              161x + 17y - 391 = 0

3 times a number is 54 less than the square of that number. Find the negative solution.
son4ous [18]

Answer:

-6

Step-by-step explanation:

3n = n² - 54

n² - 3n - 54 = 0

n² - 9n + 6n - 54 = 0

n(n - 9) + 6(n - 9) = 0

(n - 9)(n + 6) = 0

n = 9 , -6
