Answer:
x=3; y=3
Step-by-step explanation:
y = -1/2 x + 9/2
so if we multiply by 2 on both sides
2y = -x + 9
and we know that y = 3x-6
so we get
2(3x-6)=-x+9
6x-12 = - x + 9
7x = 21
x = 3
y = 3 * 3 - 6
y=3
---
x=3, y=3
You put them in the equation and they should work.

4a-3c=4×a-3×c
=4×7-3×5
=28-15
=13 this is the correct answer
I hope this answer help you
The stone takes 4sec to reach the water level.
initial velocity (u)=0
time(t)=4s
acceleration due to gravity(a)=
9.8(10 approx)
so,its final velocity will be
v=u+at
0+10×4=40
v=40m/s
Answer:
You need the distance of all four sides so that is:
2 * (5y +1) + 2 * (2y -3) which equals
10y + 2 + 4y -6 and that equals
14y -4
