F(x)=x3 −4x even odd or neither
Dennis_Churaev [7]

The answer is neither.

Let's take an odd number and substitute.

  • f(3) = 3³ - 4(3)
  • f(3) = 27 - 12
  • f(3) = 15 (odd)

Now, let's take an even number.

  • f(4) = 4³ - 4(4)
  • f(4) = 64 - 16
  • f(4) = 48 (even)

Since both even and odd numbers are possible, it is neither.

A highway has an optional toll lane that drivers may take to reduce the time they spend driving. Drivers pay a small fee to ente
djverab [1.8K]

Answer:

A. If Frank is on the toll road for 8.00 miles and then leaves the lane, how much will he have to pay total for the trip?

  • $6.25

B. Each day, Susan has to pay a toll of $10.00 when she uses the toll lane to get to school. How many miles does Susan travel on the toll lane to get to school?

  • 13 miles

C. John started a carpool with his coworkers to save money. He and his three passengers split the cost of the toll. If each person pays about $2.31 (which includes their contribution to the toll lane entry fee), how many miles do they travel on the toll lane?

  • 9 miles

Step-by-step explanation:

the toll lane charges $0.25 fixed plus $0.75 per mile driven: fee = $0.25 + $0.75miles

a) Frank ⇒ $0.25 + (8 x $0.75) = $6.25

b) Susan ⇒ $10 - $0.25 = $9.75 / 0.75 = 13 miles

c) John ⇒ $2.31 x 3 = $6.93 - $0.25 = $6.68 / 0.75 = 8.91 ≈ 9 miles. Each passenger should pay $2.33 because the total toll lane fee is $7.

A very high powered microscope would allow us to see the smallest unit of a bar of gold as shown below.
scZoUnD [109]

Answer:  Atom

Step-by-step explanation:

The atom is the smallest unit that can be found of an element so the atom is the correct answer. Atoms are the smallest because the atom retains the properties of the element. Anything smaller than an atom will not retain those qualities.

Atoms have electrons, protons, and neutrons with the last two existing in the nucleus of the atom but these cannot be said to be the smallest units because they do not have gold properties individually.

Explanation:

Since we have given that

Let the number of pounds of candy be s

Let the number of pounds of milk chocolate be

90\%x=0.9x

Let the number of pounds of caramels be

(100\%-90\%)x=10\%x=0.1x

a) Write an equation using one variable that can be used to find the total number of pounds of milk chocolate and caramels in the candy.

To find the number of pounds of caramels , the equation will be

0.1x=3\ pounds

x=30\ pounds
