Answer:
First fund: $4000
second account: $2000
Step-by-step explanation:
invest x for first fund (A) and y for second fund (B)
interest for A: x * 0.05
interest for B: y * 0.09
0.05 x + 0.09 y = 380 ....(1)
x + y = 6000 ..... (2)
y = 6000 - x ....substitute y in (1)
0.05 x + 0.09 (6000 - x) = 380
0.05x + 540 - 0.09x = 380
0.04 x = 160
x = 4000
y = 6000 -4000 = 2000
check: 4000 x 0.05 + 2000 x 0.09 = 200 + 180 = 380
Answer:
x=34/5 y= -18/5

Best way to find the intercept of 15x-12y=60, or of any line for that matter, is to put it into slope intercept form y=mx+b, where m is the slope and b is the y intercept
to do this we will need some equation manipulation to get it = to y
15x-12y=60
(15x-12y)+12y=(60)+12y
15x=60+12y
(15x)-60=(60+12y)-60
15x-60=12y
(15x-60)/12=(12y)/12
(5/4)x-5=y
y=(5/4)x-5
so m = 5/4 and b = -5
Final answer:
The y-intercept is at (0,-5)
