jek_recluse [69]

Answer:

A = 13 B =0 = 1/2   This way x in a graph can be his start running ability (time) each A value applied will divide by 1/2 to make 6.5 and when x = 21 then y can be 7 with the AB equation above as 13 x 1/2 = 6.5. add multiple 0 doesn't occur because we start with x value 21 to show the starting value. Alternately x= 137 and y = 0. Then the graph can go up or down when his running value changes as a negative decrease 137 - b = -? and a positive increase will show increase 137+b = +?.

Brian is going to buy his first home for $220,000. He has to put $22,000 down. He needs to spread the payments over 180 months t
MAXImum [283]

Answer:

<u>Use the forumula</u>

<u></u>

Payment = P(r/n)(1+r/n)nt/((1+r/n)nt-1)

For this case nt = 180, r/n = 0.035/12 and P = 220,000 - 22000 = 198000

(1+r/n)180 = 1.00292180 = 1.6892

Payment = 198000(0.00292)(1.6892)/0.6892 ≈ $1415.46
