Two equations are given below:m + 4n = 8
m = n − 2

What is the solution to the set of equations in the form (m, n)?

(4, 6)

(2, 4)

(0, 2)

(6, 8)

Answers

Answer 1
Answer:

Good morning Brainiac


m=n-2

m+4n=8

We need to solve m=n-2 for m

Substitute n-2 for m in m+4n=8

m+4n=8

n-2+4n=8

5n-2=8

Add 2

5n-2+2=8+2

5n=10

Now divide both sides by 5 so we can find the value for n

5n/5=10/5

n=2

Now substitute 2 for n in m=n-2

m=n-2

m=2-2

m=0

The amount of money left on a loan that Kira owes her grandmothers is represented by the function k(t)=280(.88)^t where k(t) represents the amount of money left on a the loan and t represents the time, in years. Find r, the percent change and explain what it represents.

Answers

Given:
k(t) = 280(0.88)^t

t = 1 ; t = 2 ; t = 3 
k(1) = 280(0.88)¹ = 280(0.88) = 246.40
k(2) = 280(0.88)² = 280(0.7744) = 216.83
k(3) = 280(0.88)³ = 280(0.681472) = 190.81

280 - 246.40 = 33.60 ⇒ 33.60/280 = 0.12
246.40 - 216.83 = 29.57 ⇒ 29.57/246.40 = 0.12
216.83 - 190.81 = 26.20 ⇒ 26.20/216.83 = 0.12

The rate is 0.12 or 12%
