Answer:
A: {(7, 12), (1, -5), (3, -10), (2, -5)}
Step-by-step explanation:
A relation should not have any repeating x values (or domains) in the group of coordinates.
B has 1 as all it's domains. B is not a function.
C lists 0 twice as it's domain. C is not a function
D lists 2 twice as it's domain. D is not a function
A is the best answer because it does not repeat any domains in the coordinates. A is a function.
Answer:
ok the answer should be A.
Step-by-step explanation:
you transform the coordinates from (x,y) to (-y,x)
this means to flip the coordinates like bring y up front and change its sign and take x to the initial y position.
for example if (-1,9) when you do the transformation you get (-9,-1). you take initial -1 to the right and bring 9 to left and change its sign.
when you are done you can see that the x axis coordinates are the same but the y axis coordinates are the direct opposite. this means that after the transformation the triangle would look like the mirror image of the original triangle.
Answer: below
Step-by-step explanation: You simply need to divide the total amount of sugar (9 lbs) by the amount that you put into each bag (2/3 lb). This expression looks kind of ugly in this form, so let's instead multiply 9 by the reciprocal of 2/3, which in this case is 3/2. The reciprocal of any number is just 1 divided by the number.
Answer:
B. 2/3
