cost of n cans of tuna.
A. C(n) = 0.09n- 0.40
B. C(n) = 0.40n - 0.90
C. C(n) = (0.90 + n) - 0.40

Answer: Hence, Option 'A' is correct.

Step-by-step explanation:

since we have given that

Cost of per cans = $0.90

Let number of cans of Tuna be n

so, Total cost of n cans be

0.90\times n\\\\=0.90n

Amount of coupon Tuna get off on total purchase = $0.40

So, According to question,

C(n)=0.09n-0.40

Hence, Option 'A' is correct.

What is the answer to 16a5 b3/8ab ?
marishachu [46]

Answer:

When we are dividing exponents, there is this rule:

\frac{a^n}{a^m}=a^{(n-m)}

So, in our case we have this:

\frac{16a^5b^3}{8ab} = \frac{16}{8}a^{(5-1)}b^{(3-1)}=2a^4b^2

What is y=2x^2-12x+16 in vertex form
Natasha2012 [34]

Answer:

y = 2(x-3)^2 - 2

Step-by-step explanation:

y = 2x^2 - 12x + 16

y = 2(x^2 - 6x + 8)

y = 2(x^2 - 6x +8 +1 -1) you "complete the square" by bringing the last term (8) up to "half of the middle co-efficient squared". Middle co-efficient is -6, half is -3, squared is 9. To get from 8 to 9 you must add 1 (+1), but if you add 1 you must subtract 1 (-1) so that you don't change the overall value of inside the bracket


y = 2(x^2 - 6x +9) - 2 (bring the -1 outside of the brackets)

y = 2(x-3)^2 - 2
