Since we are dealing with a radical then x - 5 ≥ 0, for real values
x = 4 is less than 5 , hence is not in the domain
Hello there!
According to the chart, you can see that for every lawn Nina mows, she earns $15. So it's increasing by 15 per yard.
Let's see if this will help:
1 yard= $15
6 yards = ???
I don't want to give you the answer right away, since I want you to learn how to do it. :)
I hope my hint helped!!
(If you're really stuck, take 6 times 15)!
Hope this helped!!

Answer:
K = 3/2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
k−9=5(k−3)
k+−9=(5)(k)+(5)(−3)(Distribute)
k+−9=5k+−15
k−9=5k−15
Step 2: Subtract 5k from both sides.
k−9−5k=5k−15−5k
−4k−9=−15
Step 3: Add 9 to both sides.
−4k−9+9=−15+9
−4k=−6
Step 4: Divide both sides by -4.
-4k/-4 = -6/-4
K = 3/2
C
