Answer:
(4,-2)
Step-by-step explanation:
If we are reflecting a point across the y-axis, that point must be on the same horizontal line that the pre-mage is was, this means the y coordinate must remain the same. Now we want the points on both sides of the y-axis to have the same distance. x and -x have the same distance from 0. This means you will need to take the opposite of x.
So a point (x,y) being reflected over the y-axis will give (-x,y).
( x , y)->(-x,y) means we have:
(-4,-2 )->(4,-2)
You can graph this to confirm it looks like a reflection through the y-axis.
L+S=8, L=8-S
500L+200S=2200, using L from above in this equation gives you:
500(8-S)+200S=2200
4000-500S+200S=2200
4000-300S=2200
-300S=-1800
S=6, and since L=8-S:
L=2
So Rita bought 2 large packets and 6 small packets.
Answer:
B
Step-by-step explanation:
This is the correct answer because the difference between 32 and 29 is 3 and the intial price is 32, Hence 3/32 (100)
Answer:
Function: C = 500 / n
Jane must recruit 20 more contributors or 25 contributors in total for the cost of each share to be $20.
Step-by-step explanation:
1. Cost per share, C, with respect to the number of contributors, n is
C = 500 / n
So, with 5 contributors, the price is $100 per share. $100 = 500/5
2. C= $20
20= 500 / n
20 * n = 500 * n
20n = 500
n= 25
She already has 5 contributors, so she needs 20 more.
