Answer:
We know the distance (d) equation in terms of rate (r) and time (t) as:
d=rt
Step-by-step explanation:
We have given d=336 km and t= 12 hours, so we have: 336 km = 12t <-- this is our equation.
Divide each side by 12 to solve for t:
12t/12=336/12
t= 28 km/ hour
I think it’s B I’m sorry if I’m wrong
Answer:
x = 8, y = 3
Step-by-step explanation:
Equating corresponding x and y coordinates , then
- y = - x + 5 ( multiply through by - 1 )
y = x - 5 → (1)
2x - 5y = 1 → (2)
Substitute y = x - 5 into (2)
2x - 5(x - 5) = 1 ← distribute and simplify left side
2x - 5x + 25 = 1
- 3x + 25 = 1 ( subtract 25 from both sides )
- 3x = - 24 ( divide both sides by - 3 )
x = 8
Substitute x = 8 into (1) for corresponding value of y
y = 8 - 5 = 3
<span>Points (1, 1), and (2, 2) are on a line which has a slope of 1
ok?
The only point that lies on this line is (3,3).
