Which choice is the conjugate of the expression below when x > = 6? sqrt x-6-3a. sqrt x-6+3b. sqrt x+6+3c. sqrt x-6-3d. sqrt x+6-3

Option A)

Step-by-step explanation:

Given is an expression in x as

This will be real only for x>=6

(That is given already)

Now to find conjugate

Since x-6 is inside root sign, we can take this as one term.

Next term is -3.  To find conjugate we write the root sign term as it is and change the sign of next term from negative to positive

i.e. -3 becomes +3

Hence conjugate would be

Hence option A is right

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
