Answer:
x = -1
y = 2
Step-by-step explanation:
y = x+3
x+2y = 3
substitute y
x+2(x+3) = 3
simplify
3x+6 = 3
subtract 6 from both sides
3x = -3
x = -1
y = -1+3 = 2
As the movement, it is not accelerated then
Xr = 30 T
Xp = 45(t-1)
they both will meet when x is the same, so
30T = 45T - 45
T = 3
they both will meet 3 hours after Roberto leaves, at 2 pm
Answer:
So the answer is H
Step-by-step explanation:
They could be situated as
x y z
in which case xy 5 and yz = 3
The total would be 8.
if they are situated like this
x z y
then xy = 5 and yz = 3 but its going the opposite way.
5 - 3 = 2
The perpendicular gradient to that would be 1/3x
So y= 1/3x + 4.5
