Set up a porportion,
3/5 hours / 2/5 square yards
1 hour / x square yards
simplify by cross multiplying
3/5x <span>= 2/5(1).
</span>3/5x <span>= 2/5.
</span> 3/5/3/5x = <span>2/5/3/5
x </span><span>= 10/15
</span>x <span>= 2/3
</span><span>
so she can paint </span><span>2/3 square yards in 1 hour. hope this helps!</span><span>
</span>

Range [0,∞)
Answer:
Step-by-step explanation:
To evaluate the domains of the greatest integer function, the rule is that you always round DOWN to the next whole number.
f[[3.4]] = 3
f[[.8]] = 0
f[[-1.7]] = -2
f[[-3.5]] = -4
Always round down!! Just remember that and you'll be ok!
I think that’s it f(x)=2x−12
