You could use a simple calculator it's only 10.
Answer:
26 children
Step-by-step explanation:
346-8*40
346-320
26
To find the X intercept make y =0. Then factor out a negative on the side with the equation for each of the terms, so it becomes
0=-(x^2+x+3)
0=(x^2+X+3)
0-3=(x^2+X)
-3=x(X+1)
-3=X, X intercept -3,0
-3=(X+1)
-4=X, X intercept -4,0.
These are possible X intercepts you can check by using quadratic formula as well.
Answer:
Your que. isn't very clear. Should there be a graph or diagram? Please confirm
2.5 hours, because 10 miles an hour times 2 = 20 plus half the time? 2.5
