Answer:
Step-by-step explanation:
Given
per mile
Solving (a): Linear Equation
The total charges (c(x)) is: the base charge + the rate * number of miles (x).
So, we have:
Solving (b): Cost of rent, if miles = 160
This implies that x = 160
So, we have:
Answer:
see explanation
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x + 4)² + (y + 6)² = 16 is in this form
with r² = 16 ⇒ r = = 4
---------------------------------------------------------------
given (h, k) = (5, 2) and r = 20, then
(x - 5)² + (y - 2)² = 400 ← represents the delivery area
<h2>Answer:The graph of 
is the graph of 
compressed vertically.</h2>
Step-by-step explanation:
Given that and
is always positive because
is always positive.
is always positive because
is always positive.
So,both are always positive.
So,there is no flipping over x-axis.
In ,the height of a point at
is
In ,the height of a point at
is
So,height of any point has less height in than
So,the graph of is the graph of
compressed vertically.
