We are given
(a, b) ---------------> (a, −b)
we can see that
x-values of both points are 'a'
which is same
while y-value of first =b
y-value of second =-b
so, y becomes as -y
and we know that
when a function is reflected about x-axis
then y becomes -y
so, option-C.................Answer

Rent all
55.5/3 = 18.5
74/4 = 18.5
it costs 18.5 per day
1. y = 18.5 x where y =cost and x=days
A-1
10.99 per 1/2 day
10.99 * 2 =21.98 per day
2. it costs 21.98 per day from A-1
Rentall is the better deal because it is only 18.50 per day versus 21.98 per day
Answer:
<h2>x = 3, y = 8</h2>
Step-by-step explanation:
We know:
The diagonals of the parallelogram are divided in half.
Therefore
EK ≅ KG and HK ≅ KF.
We have
EK = 7x + 5, KG = 3x + 17, HK = 3y - 11 and KF = y + 5
Equations:
(1) 7x + 5 = 3x + 17
(2) 3y - 11 = y + 5
Solutions:
(1)
7x + 5 = 3x + 17 <em>subtract 5 from both sides</em>
7x + 5 - 5 = 3x + 17 - 5
7x = 3x + 12 <em>subtract 3x from both sides</em>
7x - 3x = 3x - 3x + 12
4x = 12 <em>divide both sides by 4</em>
4x/4 = 12/4
x = 3
------------------------------
(2)
3y - 11 = y + 5 <em>add 11 to both sides</em>
3y - 11 + 11 = y + 5 + 11
3y = y + 16 <em>subtract y from both sides</em>
3y - y = y - y + 16
2y = 16 <em>divide both sides by 2</em>
2y/2 = 16/2
y = 8
