TRANSPORTATION The cost of riding in a cab is $3.00 plus $0.75 per mile. The equation that represents this relation is y=0.75x+3
Amanda [17]

Answer:

f(17) = $15.75

The amount it takes for a trip of 17 miles is $15.75

Step-by-step explanation:

Here, we want to calculate f(17)

The equation is given as;

y = 0.75x + 3

For f(17), substitute x for 17

y = 0.75(17) + 3

y = 12.75 + 3

y = $15.75

What f(17) means is that the ride was for 17 miles

$15.75 is for a trip of 17 miles

Solve the following inequality: 38 < 4x + 3 + -3x
mihalych1998 [28]

Answer:

D. x > 28

Step-by-step explanation:

Given the inequality 38 < 4x + 3 + 7 -3x simply the expression operating the common terms (the terms are common when have the same variables and exponents).

In our occasion the common terms are 4x and -3x and 3 and 7. So operate this two term for simply in one.

38 < 4x + 3 + 7 -3x = 38 < x + 10

Now substract -10 in both sides of the inequality and get the result:

28 < x

joja [24]

Answer:

$29.70

Step-by-step explanation:

when she opened her account she opened it with $900.00 she will get 2.2% interest per year.  she leaves it for 1 1/2 years.  what you do it you multiply 900.00 x 2.2%    that will give you $19.80 then you have to divide it by 2 and that will give you 9.90.  then you add 9.90 + 19.80 = 29.70


900. x 2.2% = 19.80

19.80 divide by 2 = 9.90

9.90 + 19.80 $ 29.70

For each of the following distance matrices of graphs, identify the diameter, radius and center. Assume the graphs vertices are
mylen [45]

For each of the following distance matrices of graph, the

  • The diameter = 3
  • The radius of the graph is given as 2

<h3>What is the diameter of the graph?</h3>

This is used to refer to the fact that there would be a maximum distance that exists between the pair of vertices.

<h3>What is the radius of the graph</h3>

This used to refer to the minimum eccentricities of the vertices

<h3>What is the center of the graph?</h3>

This is used to show all of the vertices that have minimum eccentricities.

<h3>How to solve the matrix</h3>

We have

e 1 = 3

e 2 = 3

e3 = 2

e4 = 3

e 5 = 3

e 6 = 3

e 7 = 3

e8 = 2

e 9 = 3

e 10 = 2

Then the the diameter = maximum eccentricity = 3

The radius = minimum eccentricity = 2

center = [3, 8,10]
