ANSWER
The correct answer is
EXPLANATION
The mapping for reflection across the x-axis is given by
Given
. We can let
we can write the ordered pair
or
as the ordered pair of the preimage of
.
The image function will have the ordered pair
or
.
That is, we negate all the y-coordinates.
Therefore
.
P = 8/v
1/2 = 8/v
multiply v on both sides
1/2 v = 8
multiply 2/1 on both sides (the reciprocal of (1/2)
v = 16
Letter D
Answer:
(x+2)
Step-by-step explanation:
factor out the equation and get
(x+2)(6x-5)
Answer:
Cost of Television = $294
Step-by-step explanation:
7% discount means 7/100 = 0.07 LESS
So we need to multiply by 1 - 0.07 = 0.93
Also, 10% MORE, or extra, means 10/100 = 0.10 MORE
So we need to multiply by 1 + 0.10 = 1.1
Let cost of television be "c", so we can say:
- 7% discount would mean cost to be c(0.93) = 0.93c
- 10% with interest would mean cost to be c(1.10) = 1.10c
The difference is 49.98. So we subtract lower value (0.93c) from larger value (1.10c) and equate to 49.98 and solve for c:
Cost of Television = $294
110/50=2.2 (each person consumes 2.2 kg of rice)
50+20 (the people who join)=70 total of people
70X2.2= 154 kg of rice.
