Solve the following equation:
21 - x = 4x - 4
X =
What is X

5

Step-by-step explanation:

21 - x = 4x - 4

25 - x = 4x

25 = 5x

25/5

= 5

x=5

Step-by-step explanation:

21-x=4x-4. You first would subtract 21 from both sides, so 21-21 is gone, and -4-21 is -25. Next, you would subtract 4x from both sides, -x-4x= -5 and 4x-4x is 0, aka gone. Now, you have -5x = -25. You now divide both sides by -5. -5/-5 cancels out. -25/-5 is 5. All you are left with is x = 5(because a negative divided by a negative is a positive). Hope this helps! :)

step-by-step explanation:

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
