Function c is defined by the equation c(n) = 50 + 4n. It gives the monthly cost, in
dollars, of visiting a gym as a function of the number of visits, n. Find the value of
c(7).

Answers

Answer:

The value of function at n = 7 is 78.

Step-by-step explanation:

Given function is:

c(n) = 50 + 4n

Here,

c represents the cost monthly cost of gym

n represents the number of visits to the gym

We have to find the value of c(7).

We will put n = 7 in the function.

Thus,

c(7) = 50 + 4(7)

c(7) = 50 + 28

c(7) = 78

Hence,

The value of function at n = 7 is 78.

The value of c(7) in the function c(n) = 50 + 4n is = 78

The function is defined as follows:

c(n) = 50 + 4n

where

function c is defined by the equation above

n is the number of visit

The function gives the monthly cost in dollars.

Therefore,

The value of c(7) can be found as follows:

c(7) = 50 + 4n

c(7) = 50 + 4(7)

c(7) = 50 + 28

c(7) = 78

Multiply both sides by (-1)

Flip the inequality sign since you are multiplying by a negative number

     2z+9  < 0

Divide both sides by  2  

     z+(9/2)  < 0

Subtract  9/2  from both sides

Step-by-step explanation:

Step(i):-

Given  [tex]n^{th}[/tex] of the sequence

aₙ  = n + 3 ..(i)

 put n =1

a₁ = 1 +3

a₁ = 4

The first term of the sequence = 4

Put n =2 in equation (i)

a₂ = 2+3

a₂ = 5

The second term of the sequence = 5

put n=3 in equation (i)

a₃ = 3+3 = 6

The third term of the sequence = 6

Put n=4 in equation (i)

a₄ = 4 +3

a₄ = 7

The fourth term of the sequence = 7

Put n = 5 in equation (i)

Step 2: Solve for x

Substitution

Substitute in y:                                                                                                -2x + 4(-6x - 16) = -2Distribute 4:                                                                                                    -2x - 24x - 64 = -2Combine like terms:                                                                                       -26x - 64 = -2[Addition Property of Equality] Add 64 on both sides:                                -26x = 62[Division Property of Equality] Divide -26 on both sides:                            x = -31/13

Is the relation in the table below a function?

Answers

Answer:

No

Step-by-step explanation:

A relation is a function if every x-value has exactly one y-value.

Because the x-value 1 has two y-values (-3 and 3), the relation is not a function.

Plotting (1, -3) and (1, 3) will produce a vertical line that intersects the function at two points.

Therefore, the relation is not a function.
