Step-by-step explanation:
the red point is (4, -5).
so, y - (-5) = -1/7(x - 4)

Answer:
1). 
= (200 - 
)
2). Inverse function represents the age of the client and 'x' represents the maximum heart rate of the client.
Step-by-step explanation:
Function representing the maximum heart rate is,
f(x) = 0.85(220 - x)
Here x = age of the client
Equation form of the function will be,
y = 0.85(220 - x)
To get the inverse of the given function, replace 'x' by 'y' and 'y' by 'x' and solve for y.
x = 0.85(220 - y)
220 - y =
y = 220 -
Now convert this equation into a function.
= (200 - )
Here inverse function represents the age of the client and 'x' represents the maximum heart rate of the client.

5.7909000*10^7=Mercury
1.08208930*10^8=Venus
1.49600000*10^8=Earth
7.785472000*10^9=Jupiter
2.871000000*10^9=Uranus
4.495000000*10^9=Neptune
Step-by-step explanation:
All I was taught in math class was to count the places until it is between one and ten and how many places is your exponent after 10.
Step-by-step explanation:
the function actually is
y = 40(x - 1) + 70 = 40x - 40 + 70 = 40x + 30
still, the slope (the factor of x) is 40.
that means y (the cost) increases by 40 for every additional hour (x increases by 1).
so, the rate of change (slope) is 40/1 = $40 per hour.
You can identify points on a graph by looking at them. The x coordinate is the horizontal line. and the vertical line is the y axis
