what's its speed? well, it traveled √(52) in 2 seconds, so is simply √(52)/2, which is about 3.6 units per second.
Answer:
the graph is a linear
Step-by-step explanation:
14x +5y =1000
let X=0
14(0)+5y=1000
5y=1000
y=200
y(0;200)
let y =0
14y+5y=1000
14x+5(0)=1000
14x=1000
X=71.43
X(71.43;0)
Maybe 45 but get someone else to check
