The function t(x) = x + 6 determines how many cans of soup a food truck needs to stock, where x is the number of shifts the crew

is going to work in the truck. The crew uses c(t(x)) to find the amount of money to spend on soup. The function c(x) = 2x + 4. Solve for how much money must be spent when the crew is going to work 4 shifts.

C(t(x)) means to plug x + 6 into c(x).

c(t(x)) = 2(x + 6) + 4

c(t(x)) = 2x + 16

Now, let x = 4.

c(t(x)) = 2(4) + 16

c(t(x)) = 24

Answer: $24

Evaluate the function below for x=3<br><br> f(x)=2x^3-x^2-4x+9
elixir [45]
Hello,

f(x)=2x^3-x^2-4x+9=(((0+2)x-1)x-4)x+9

f(3)=(((0+2)*3-1)*3-4)*3+9=((2*3-1)*3-4)-3+9=(5*3-4)*3+9=11*3+9=33+9=42

or

f(3)=2*3^3-3^2-4*3+9=2*27-9-12+9=54-12=42

Solve for x.<br> −7≥13−5x
Sergio039 [100]

Answer:

\[=>x\geq 4\]

Step-by-step explanation:

Given inequality is \[−7\geq13−5x\]

Simplifying:

\[5x\geq13+7\]

\[=>5x\geq20\]

\[=>x\geq \frac{20}{5}\]

\[=>x\geq 4\]

Hence the solution for the given inequality is represented by  \[=>x\geq 4\]

This means that the original inequality will be true only for those values of x which are greater than or equal to 4.

If a sum of several numbers is odd, then at least one of the numbers is itself odd.
labwork [276]

Answer with Step-by-step explanation:

We are given that if sum of several numbers is odd

We have to prove that at least one of the number is itself odd.

Suppose, we have three numbers

a=6 , b=7,d=8

Sum of numbers=6+7+8=21=Odd number

We know that sum of two odd numbers is always an even number.

Sum of an odd number and an even number is always an odd number.

If we take even odd numbers then sum is always an even number and sum of odd odd numbers then the sum is always an odd number.

7+5+3=15

7+3+9+5=24

Sum of even numbers is always an even number.

Hence, there are atleast one numebr is odd then the sum of several number is odd.

vivado [14]

Answer:

Step-by-step explanation:

Given that a basketball coach will select the members of a five-player team from among 9 players, including John and Peter.

Out of nine players five are chosen at random.

The team consists of John and Peter.

Hence we can sort 9 players as I group, John and Peter and II group 7 players.

Now the selection is 2 from I group and remaining 3 from II group.

Hence no of ways of selecting a team that includes both John and Peter=2C2*7C3=35

Total no of ways = 9C5=126

= \frac{2C2*7C3}{9C5}=\frac{35}{126} =\frac{5}{18}
