Answer:
y=-1/3x-11/3
(Not sure what point slope form is, but this is the equation for the points)
First you convert the whole number into a fraction. Since you already have a fraction of 5/16, convert 2 into 16th's, which would be 32/16. Add 5/16 to 32/16 and you have 37/16. Divide 16 into 37, and your result will be a decimal. Your final answer will be 2.3125. I hope this helps!
Please use " ^ " to denote exponentiation:
<span>f(x) = –(x + 8)^2 – 1
Find the first derivative: f '(x) = -2(x+8)(1)
Set this = to 0: -2(x+8) = 0
solve for x: x = -8
Divide the number line into subintervals based upon x=-8:
(-inf, -8) and (-8, inf)
Choose a test value for x from each interval, e. g., -10 from the first interval and 20 from the second.
Subst. this test value into the derivative, shown above.
If the result is + the function is incr on that interval; if - the fn. is decr.

Answer:
Coupon 2
Step-by-step explanation:
If you were to use coupon 1 the price will be $28.80 because %40 of $18 will be $10.80 (18 x 0.40) then add it to the other 18$ and it will sum up to $28.80. If you were to use coupon 2 the price will be $27 because if you were to take %25 of the sum of both sweaters ($36) it would be $27 (36 x 0.25).
