Hmm
rate=change in price/change in number of books

see left one
notebooks,money
6,1.8
12,3.6
change in money/change iin notebooks=(3.6-1.8)/(12-6)=1.8/6=0.3
rate is 0.3 for left one
rate is 30 cetns per notebook


right one
number of books,price
3,1.05
6,2.1
change in money/change in notebooks=(2.1-1.05)/(6-3)=1.05/3=0.35
price is 35 cents per
12*35=420 cents=$4.20

the blank on bottom right is $4.20
the rate on the left is $0.30 per notebook
the rate on the right is $0.35 per notebooks
left one is the better deal

Answer:

The value of f(2) would be -40.

Step-by-step explanation:

Given function is,

f(x) = 2x^3 - 3x^2 - 18x - 8

Substituting x = 2 in the above function,

We get,

f(2) = 2(2)^3 - 3(2)^2 - 18(2) - 8

=2(8) - 3(4) - 36 - 8

=16 - 12 - 44

\implies f(2)= -40

Hence, the value of f(2) would be -40.

1. The answer is 16^2, so B.

16 x 16 = 256

2. The answer is 17, so B.

Some of the factor of 68 are: 1, 2, 4, 17, 34 and 68.

3. The answer is 15, so B.

Only 15 is composite since it contains more than a factor, which are 3 and 5. The rest of the numbers are prime since they only contain a factor.

4. The answer is 2^2^3^7, so B.

The factor tree:

84

2 x 42

2 x 2 x 21

2 x 2 x 3 x 7

Hope this helps! :)

Amelie's cat is 6 years older than her dog. The sum of their ages is 14 years.    How old is Amelie's dog
creativ13 [48]
C+d=14
c-6=d
then you will plug c+6 in the first equation and you will get:
c+c-6=14
then you get
2c=20
c=10, so the cat is ten years old
the cat is 6 years older than the dog, so the dog is 4 years old
hope that helps :)
