Answer:
y = $122 + $49.99(x - 1)
Step-by-step explanation:
Let's use the general equation y=c+d(x−1), where c represents the initial charge and x represents the specific hour: {1, 2, 3}.
Then:
First hour: $122 = c + d(1 - 1) = c
If c = $122, then:
Second hour: $171.99 = $122 + d(2 - 1), or $49.99 + d(1), so that d = $49.99.
Third hour: $221.98 = $122 + $49.99(3 - 1), or
$99.98 = $99.98
Thus, the governing equation becomes
y = $122 + $49.99(x - 1)
7.772 million people live in Cairo.
658,893 people live in Washington DC.
So it's false.
Point C is 1 unit above the X axis and point c’ is 1 unit below the x axis, because they are equal distance from the x axis the line of reflection is the x axis
The answer is c.
Here it is step by step :

Answer:
x = 5.5 (Fraction 5 and one-half)
Step-by-step explanation:
18 - 7x = -20.5
-18 -18
-7x = -38.5
/-7 /-7
x = 5.5
