F(x)=250-35x
x is the number of months at since the first month. It is 35x because he would minus 35 which is the monthly deposit × the number of months.

$250 - in his account

$35 per month out of (minus $35 per month from his account)

$250 - 1 · $35 - after the first month

$250 - 2 · $35 - after the second month

$250 - 3 · $35 - after the third month

...

n - the number of a month

The function:

<h3>f(n) = 250 - 35n</h3>

Domain:

250 - 35n > 0      <em>subtract 250 from both sides</em>

-35n > -250      <em>change the signs</em>

35n < 250     <em>divide both sides by 35</em>

n < 7.142.... → n < 8 → n ∈ {0, 1, 2, 3, 4, 5, 6, 7}

Find the length here
Vera_Pavlovna [14]

Answer:

The correct answer is

D) 66.35

The sine of the angle = the length of the opposite side. the length of the hypotenuse.

The cosine of the angle = the length of the adjacent side. the length of the hypotenuse.

The tangent of the angle = the length of the opposite side. the length of the adjacent side.

So in shorthand notation:

sin = o/h   cos = a/h   tan = o/a

Substitute 2m + n =0 and m + 2n =3
melamori03 [73]

There are several ways you can solve this problem if you're trying to solve for m and n. You can substitute, or systems of equations. However, I'm going to use substitution:

2m + n = 0 => n = -2m

We can input that in for the other equation:

m + 2n = 3 now becomes: m + 2(-2m) = 3

Now we can solve:

m + 2(−2m) = 3

m + −4m = 3

(m + −4m) = 3 (Combine Like Terms)

−3m=3

m = -1

Now we can input that value in to solve for n:

We said that n = -2m, and m = -1, so n = -2(-1):Answer:

n = 2

Your final answer is m = -1, and n = 2, which can also be written as (m,n) = (-1,2)

----------------------

However, if you were solving for m+n:

You would add the two equations!:

2m + n = 0

m + 2n = 3

----------

3m + 3n = 3

Now, you can take 3 common:

3(m+n) = 3

m + n = 1

Your final answer for what m + n equals 1!
