2900 dollars is placed in an account with an annual interest rate of 9% Wirte an equation that calculates how many dollars will
valentinak56 [21]

Answer:

The amount that will be in the account will be $(2900 +261x)

Step-by-step explanation:

We know that the amount of money that will be in the account will be a sum of the initial principal ($2900) and the interest that is accrued after x years.

Since we already know the principal, we will have to calculate the interest that is accrued after x years.

we can use the formula:

Interest = (principal X rate X time)/ 100

Interest = (2900 \times 9 \times x)/100=261x

Therefore the amount that will be in the account will be $(2900 +261x)

What is an equation of the line, in point-slope form, that passes through the given point and has the given slope?
MAXImum [283]

Answer:

equation of line:

y = mx + b....(1)

slope = m = 2/3

y-intercept = b = ?

putting the point (5,6) and slope(2/3) in equation(1)

6 = (2/3)(5) + b

6 = 10/3 + b

b = 6 - 10/3

b = (18 - 10)/3

b = 8/3

putting value of b and m in equation(1)

y = (2/3)x + 8/3


Step-by-step explanation:

Choose Yes or No to tell if the fraction 3 5 will make each equation true. 7 20 + □ = 19 20 Choose... □ + 3 10 = 3 15 Choose...
OleMash [197]

Answer:

True ; false ; False ; true

Step-by-step explanation:

Equation 1:

7 20 + □ = 19 20

19 / 20 - 7/20

(19 - 7) / 20

12/ 20 = 3/5

Equation 2:

□ + 3 10 = 3 15

3/5 + 3/10

(6 + 3) / 10 = 9/10

Equation 3:

1 2 + 2 3 = □

1/ 2 + 2/3

(3 + 4) / 6

7 / 6

Equation 4:

1 10 + 1 2 = □

1/10 + 1/2

(1 + 5) / 10

6 / 10 = 3/5
