Answer:
"Take the square root of both sides of the equation"
A is correct
Step-by-step explanation:
We are given quadratic equation
We need to solve for x. We have to isolate x here.
Here square on x. So, first we get rid of square.
Taking square root both sides to get rid of square.
For example:
a2=25
sqare a2 = +- sqare 25
x2=9/16 to solve for x
sqare x2 +- sqre 9725
x=+- 3/5
Hence, "Take the square root of both sides of the equation"
Answer:
(3,-2)
Step-by-step explanation:
Equal both equations 2/3 x-4=-2x+4
8/3 x=8
x =3
Input 3 into either original equation to find y
y=-2
Answer:
x=2

Answer:
Step-by-step explanation:
To find (c.g)(x) we basically use the function d(x) as your variable, x, and plug it into c(x). So we replace every x in c(x) with the function d(x), 
c(g(x))=4(x^{2} +5x)-2
c(g(x))4
+20x-2
Answer:
John Roberts must serve a minimum of 12, 543 days to surpass John Mrshall's record of justice.
Step-by-step explanation:
John Marshall = 2079 + 10, 463 = 12, 542 days
Now, we have to add 1 more day to pass John Marshall because if we do not, we would only be on the same level as John Marshall and NOT EXCEEDING him.
