Five less than twice what negative number squared is 157 <- put into an expression
-5 + 2(-x^2) = 157
Now simplify:
-5 + -2x^2 = 157
-2x^2 = 162
-2x^2 - 162 = 0
2x^2 + 162 = 0
x^2 + 81 = 0
The points for this graph are (3,0) and (0,2). Looking at the point to the right, you go left or right before you go up and down. You first go to the right 3 times, but you don't go up or down. So this point is (3,0). Looking at the next point you don't go left or right at all, but you do go up two spaces, so this point is (0,2).

Explanation:
Compute:
35 ÷ 16 = 2.1875 = 2R3
2 ÷ 16 = 0.125 = 0R2
Jot down the remainders:
======
Let's look at another example: ![\sf 325_{10} = [?]_{16}](https://tex.z-dn.net/?f=%5Csf%20325_%7B10%7D%20%3D%20%5B%3F%5D_%7B16%7D)
Compute:
325 ÷ 16 = 20.3125 = 20R5
20 ÷ 16 = 1.25 = 1R4
1 ÷ 16 = 0.0625 = 0R1
Jot down remainders:
=====
![\sf 325_{10} = [145]_{16}](https://tex.z-dn.net/?f=%5Csf%20325_%7B10%7D%20%3D%20%5B145%5D_%7B16%7D)
Another example: ![\sf 500_{10} = [?]_{15}](https://tex.z-dn.net/?f=%5Csf%20500_%7B10%7D%20%3D%20%5B%3F%5D_%7B15%7D)
Compute:
500 ÷ 15 = 33.33... = 33R5
33 ÷ 15 = 2.2 = 2R3
2 ÷ 15 = 0.13... = 0R2
Jot down remainders:
=====
![\sf 500_{10} = [235]_{15}](https://tex.z-dn.net/?f=%5Csf%20500_%7B10%7D%20%3D%20%5B235%5D_%7B15%7D)

Answer:
Single Blind (option 1)
Step-by-step explanation:
The subjects don't know which cream they have but the technicians do.
If the subject knows which cream they have then they can be influenced by the placebo effect. If they don't know but the technicians do then the technicians will be able to look at unbiased responses from the subjects and tell if it works or not. If the technicians don't know which cream each subject has then they won't be able to learn anything from the responses. The technicians need to know which cream each subject has and the subjects can't know which cream they had.
