First realize that 7.14 = 7.14/1
Then multiply this by 100/100
714/100
Then reduce
357/50
Part A: D) x is positive, y is negative.
Part B: C) both x and y are negative.
Part A:
P' is found by rotating P 90° counterclockwise about the origin. This makes the coordinates (x,y) transform to (-y,x). Thus (-2,-1) maps to (1,-2).
Part B:
Q'' is found by rotating Q 90° counterclockwise about the origin, then reflecting across the x axis. This makes the coordinates (x,y) first transform to (-y,x), then makes the new y-coordinate the opposite sign. Thus (1,2) first maps to (-2,1), then to (-2,-1).
Answer:
You're right, the answer is C.
Step-by-step explanation:
Are you allowed to use a calculator? if you are allowed, for number 13 you should put “If you put 678 into a calculator and divide it by 2, you get 339. If you divide it by 3, you get 226. And if you divide it by 6, you get 113.”They are all numbers without decimals.
I’m not sure about 14 though. Sorry :( But i hope i helped.
Answer:
4÷1/5×4=80
divide 4 and 1/5 and you will get 20 then multiple by 4 and you will get 80
