 WE CAN FIND SLOPE ON A GRAPH BY USING BELOW FORMULA :-

If two point on graph are given.

such that ,

there coordinates are (x,y) & (x' ,y').

Then,

$m = \frac{ {y}^{.} - y}{{x}^{.} - x}$

Michelle deposited $1,385 into a savings account with a simple interest rate of 2.89% per year. If Michelle does not touch the f

Answer:

$1,665.19

Step-by-step explanation:

Interest=PRT/100 where P is the principal amount deposited by Michelle, R is the rate offered per year in terms of percentage, T is the period in years

Substituting P for $1385, T for 7 years, R for 2.89% we obtain interest as follows

Interest=$1,385*2.89*7 years/100=$280.1855

Balance after 7 years will be the sum of principal amount and interest gained

Balance=$1,385+$280.1855 =$1,665.1855

Rounding off to 2 decimal places

Balance=$1665.19

Therefore, Michelle's balance is $1,665.19

( simultaneous equations)

daser333 [38]

Answer:

See method below.

Step-by-step explanation:

m/n + n/3 = 2

2/m + n = 4

First eliminate the fractions by multiplying the first equation by 3n:-

3m + n^2 = 6n...........(1)

and the second equation by m:-

2 + mn = 4m..............(2)

Now we solve using substitution:-

From equation (2):-

4m - mn = 2

m = 2 / (4 - n)

Now substitute for m in equation (1):-

6/ (4 - n) + n^2 = 6n

6 + n^2(4 - n) = 6n(4 - n)

6 + 4n^2 - n^3 = 24n - 6n^2

n^3 - 10n^2 + 24n - 6 = 0

This will not factor so we could solve this using graphical software.

To find the values of the variable m we substitute the found values of n into one of the original equations and solve for m.

You can afford a $1350 per month mortgage payment. You’ve found a 30 year loan at 7% interest.

Mice21 [21]

A) 45 because 1350 divide by 30 equals 45. So 45 dollars u can afford

In Mrs. Trainer's math class, Siobhan's first five math quiz scores are 70, 98, 83, 66, and 41. Siobhan takes the sixth math qui

nasty-shy [4]

The answer will be a because if you add 70 +98+83+66+41 divided by 5 is 325.2 and I'd u add 81 and divide it by 6 then it will equal 371.5 so it will increase
