The equation is the correctly in the right spot
The solution is x = 2 , y = 3.5
<h3>What is Equations?</h3>
An equation is a mathematical statement that is made up of two expressions connected by an equal sign
Given:
2y= - x+9 ......................( 1)
3x-6y=-15 ........................ (2)
From (1),
x = 9 - 2y ........................... (3)
Put x = 9 - 2y into (2) , then becomes :
3 ( 9 - 2y ) - 6y = - 15
27 - 6y - 6y = - 15
27 - 12y = - 15
27 + 15 = 12y
42 = 12y
y = 3.5
Now, put y = 3.5
x = 9 - 2y
x = 9 - 2 (3.5 )
x = 9 - 7
x = 2
Hence, x = 2 , and y = 3.5.

Answer:
true
Step-by-step explanation:
V(t)=t^2+2t+1 integrating we get d(t)
d(t)=t^3/3+t^2+t or more neatly
d(t)=(t^3+3t^2+3t)/3 so
d(2)=(8+12+6)/3
d(2)=26/3
So the particle moves 9 feet (to the nearest foot) in the first two minutes.
