First you must derive the equation to find the slope:
y = 3x ^ 2 - 3
y '= 6x
Then, for x = 1 we have the slope is:
y '(1) = 6 (1) = 6
Then the equation of the line with slope equal to 6 and passing through point (0, -3) is:
y = 6x - 3
The slope is m = 6
A because:
B =(-16) & 16
C=16 & 20
D= 16 & -16
Answer:
C = $137.50
Step-by-step explanation:
Okie dokie, so we already know he charges $50 just for a service call, plus 25 per hour, so let's say the total charge is C.
Now, let's make an equation:
C = 50 + 25(3.5)
Now, multiply 25 and 3.5 together:
C = 50 + 87.5
Now we just combine the like terms:
C = $137.5
Hope this helps :)
