Answer:
(0,1/5) and (1/9,0)
Step-by-step explanation:
3/5x +1/3y=1/15
To find intercepts, plug in 0
y-intercept: 3/5(0) + 1/3y=1/15
y=1/15*3 = 3/15 = 1/5 or 0.2
x-intercept: 3/5x + 1/3(0) = 1/15
3x=1/15*5/3
x=5/45= 1/9
Answer:
a=-4, b=-4. (-4, -4).
Step-by-step explanation:
-3a+7b=-16
-9a+5b=16
-------------------
-3(-3a+7b)=-3(-16)
-9a+5b=16
---------------------------
9a-21b=48
-9a+5b=16
------------------
-16b=64
b=64/-16
b=-4
-3a+7(-4)=-16
-3a-28=-16
-3a=-16+28
-3a=12
a=12/-3
a=-4
