Answer:
1,1 brainless pls? ..... ..
when you find x-intercept, you are finding the coordinate when y=0, hence sub y=0,
-8x-16=0
8x=-16
x=-2
Answer:
y=x*6
Step-by-step explanation:
it is y=x*6 because the y axis is every x's six times.
It would be $75.
Becuase, $15 divided by 2 years equals $7.50 a year.
Therefore, $7.50 X The 10 years would be $75.
Hope that helped.
Answer:
Define F as fathers age and S as sons age right now.
Then now they are
(1) 3S = F
and six years ago they were
(2) 5*(S-6) = F-6
calculate 5*(S-6)
5S - 30 = F-6
Subtract left and right side by -F
Add 30 to left and right side
5S - F = 24
Put (2) 3S = F into the equation above
5S - 3S = 24
2S = 24
S = 12
insert result in (2) 3S = F
3*12 = F
36 = F
Step-by-step explanation:
So the son is 12 years, and the father is 36 years.
