Slope:7
y-int:-2
slope is the one with x and y-int is b
The number (or expression) in the parenthesis is what you would plug into x for the given equations. for example f(3)=4(3)=2 and solve
Answer:
Maximum at (-6,51), or value of f(-6) = 51
Step-by-step explanation:
f(x) = 8*log(x+7)-8*x+3
differentiate with respect to x
f'(x) = 8/(x+7) -8
To find maximum, set f'(x) = 0
f'(x) = 8/(x+7) -8 = 0
solver for x
x= -6
evaluate f(x) at x=-6
f(-6) = 8log(-6+7) - 8(-6) + 3
= 0 +48 +3
= 51

Answer:
the total price of the CD, including tax is $14.31
Step-by-step explanation:
The computation of the total price of the CD including tax is shown below:
= Sale price - off percentage + sales tax
= $15 - ($15 × 10%) + 6% of the remaining value
= 15 - $1.5 + 6% of the remaining value
= $13.50 + 6% of $13.50
= $13.50 + $0.81
= $14.31
Hence, the total price of the CD, including tax is $14.31
