Answer:

-3m-16n+6

Step-by-step explanation:

So yeah as the question says you would combine the like terms. So add the m terms together (5m-8m), then the n terms (-7n-9n), and the 6. All together that would get you -3m-16n+6.

At what rate would u need to invest $25000 to earn $5000 in 2 years?
Vlad [161]

Answer:

The appropriate interest rate would be 10%.

Step-by-step explanation:

Without further info I must assume that you want "simple interest" on the $25000 principal.  The appropriate formula for simple interest is:

i = p*r*t, where p is the principal amount, r is the interest rate as a decimal fraction, and t is the time in years.

                                                                                                    i

We want the rate, r, so we solve this equation for r:    r = -------------

                                                                                                   p*t

Now we're in a position to substitute the known values of i, p and t and to calculate r from them:

            $5000                   1

r = ---------- ------------- = --------------- = 0.10  

     ($25000)(2 yrs)            10

The appropriate interest rate would be 10%.

(30PTS) What are the slopes of the asymptotes of a hyperbola with equation x^2/2^2-y^2/6^2=1
Akimi4 [234]

Answer:

2x2−3y2=6or2x26−3y26=1 or. x23−y22=1or(x−0)2(√3)2−(y−0)2(√2)2=1. This is standard form of the equation of a hyperbola with center.

Step-by-step explanation:

c2 = a2 + b2. Every hyperbola has two asymptotes. A hyperbola with a horizontal transverse axis and center at (h, k) has one asymptote with equation y = k + (x - h) and the other with equation y = k - (x - h).
