k = - 2

evaluate h(2), equate to 18 and solve for k

h(2) = - 2k + 14 = 18 ( subtract 14 from both sides )

- 2k = 4 ( divide both sides by - 2 )

k = - 2

h(x)= -kx + 14

18 = -k*2 + 14   since x=2

18 = -2k +14

subtract 14 from each side

4 = -2k

divide by -2

-2 =k

How are fractions and decimals related
Airida [17]
A fraction is a short way to write a division problem. When you see a fraction, it means "the top number divided by the bottom number". When you actually DO the division, the answer is the decimal that's equal to the fraction.

What is the volume of a shipping cube with dimensions of 2 and 1/2 feet
Fantom [35]

For this case we have that by definition, the volume of a cube is given by:

V = l ^ 3

Where:

l: It's the side of the cube

According to the statement data:

l = 2 \frac {1} {2} = \frac {2 * 2 + 1} {2} = \frac {5} {2}

Substituting in the formula we have:

V = (\frac {5} {2}) ^ 3\\V = \frac {5 ^ 3} {2 ^ 3}\\V = \frac {125} {8}\\V = 15.625

Thus, the shipping cube volume is15.625 \ ft ^ 3

Answer:

15.625 \ ft ^ 3
