c = 175 + 5m is the  equation for calculation of total cost (c) at the end of

the evening for a given number of miles (m).

For travelling 45 miles, total cost at the end of the evening is $400

What is equation and linear equation?

A statement that shows the equality between two mathematical expressions by connecting the two mathematical expression with an equal to (=)  sign is called equation.

A one degree equation is known as linear equation.

Here,

Let the number of miles be m

Fixed cost for renting a limo for prom = $175

For travelling one mile by limo, amount charged = $5

For travelling m miles by limo, amount charged = $5m

Total cost for renting a limo for pron = $(175 + 5m)

By the problem,

c = 175 + 5m

This is the equation for calculation of total cost (c) at the end of

the evening for a given number of miles (m).

Now,

Putting m = 45 in the above equation,

[tex]c = 175 + 5 \times 45\\c = 175 + 225[/tex]

Equation of the line that passes through the points in the table:

x=0,1,2,3

y=10,7,4,1

is y = -3x + 10

What is Equation of the Line?

A straight line's general equation is y = mx + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis. On the y-axis, this value c is referred to as the intercept. Key Concept. Y = mx + c is the equation for a straight line with a gradient of m and an intercept of c on the y-axis.

Since, The Equation of the line:

y = mx + b

where m is the slope

For finding slope passing through (0,10) and (1, 7)

m = (y2 - y1)/(x2 - x1)

m = (7 - 10) / (1 - 0)

m = -3/1

m = -3

Therefore, the slope of the line is −3.

Now use the slope and either of the two points to find the y-intercept.

y=mx+b

10 = (-3)(0) + b

10 = b

Write the equation in slope intercept form as:

y=mx+b

y = -3x + 10

Hence, the equation of the line is y = -3x + 10

Now, for other two points (2, 4) and (3, 1)

For finding slope passing through (2, 4) and (3, 1)

m = (y2 - y1)/(x2 - x1)

m = (1 - 4) / (3 - 2)

m = -3/1

m = -3

Therefore, the slope of the line is −3.

Now use the slope and either of the two points to find the y-intercept.

y=mx+b

4 = (-3)(2) + b

4 = -6 + b

4+6 = b

b = 10

Write the equation in slope intercept form as:

y=mx+b

y = -3x + 10

Hence, the equation of the line is y = -3x + 10

Answer:

Step-by-step explanation:

We can rewrite:

15(2x-10) + 4x = -2(15x+4)

gives

30x - 150 + 4x = -30x -8

Adding 30x on both sides and adding 150 on both sides gives us:

30x + 4x - 150 + 30x + 150 = -30x - 8 + 150 + 30x

which gives us: 64x = 142

We can now divide both sides by 64, which gives us:

x = 142 / 64 = 2.21875

Answer:

  f(x) = 5/6x +21

Step-by-step explanation:

You want the equation of the line with slope 5/6 through point (-18, 6) written using function notation.

Given a slope and a point, it can be useful to write the equation of the line in point-slope form:

  y -k = m(x -h) . . . . . . . line with slope m through point (h, k)

The line of interest has slope m = 5/6 through point (h, k) = (-18, 6), so its equation can be written as ...

  y -6 = 5/6(x -(-18))

  y = 5/6x +15 +6 . . . . . eliminate parentheses, add 6

  y = 5/6x +21

Function notation gives a name to the relation, and identifies the independent variable. We want to call this f(x), meaning the name of the relation is "f", and the independent variable is "x". Essentially, "f(x)" replaces "y" in the above equation:

  f(x) = 5/6x +21

The solutions are x = -1 and y = 3 of the given system of equations 2x+y=1, −3x+4y=15 which is determined by Cramer's rule.

We put the tiles in the right order and entered the final result for each x and y.

The main principle is to split determinants as shown by the vertical bars (these are not absolute value bars).

The determinant of the matrix [tex]\begin{bmatrix}2 & 1 \\-3 & 4 \\\end{bmatrix}[/tex], which are the coefficients of the left-hand side of each original equation supplied to you, is in each denominator.

This matrix's numerators are somewhat different. The x determinant requires you to replace the first column with 1 and 15 to produce [tex]\begin{bmatrix}1 & 1 \\15 & 4 \\\end{bmatrix}[/tex], which aids in determining the x solution. The y solution is similar, except we replace the y column rather than the x column. This explains the [tex]\begin{bmatrix}2 & 1 \\-3 & 15 \\\end{bmatrix}[/tex].

You just evaluate each determinant using the formula once you have the right determinants in place and then simplify the outcomes.

Thus, the solutions are x = -1 and y = 3 of the given system of equations 2x+y=1, −3x+4y=15 which is determined by Cramer's rule.

Looking at the graph of f(x), we can see that some values of y have two corresponding values of x.

Since the inverse function changes y with x and vice versa, there will be values of x that will have more than one corresponding value of y, this way it will not be a function.

In order to ensure that f(x) has an inverse function, we need a domain restriction that makes every value of y have only one corresponding value of x.

The domain restrictions that cause every value of y to have only one corresponding value of x are:

x >= -1

x <= -1

0 <= x <= 3

Therefore the correct options are the first, third and fourth options.

The workout plan A lasts 1 hour and 30 mins and the workout plans B last around 30 mins only, solved through elimination method.

The equations are either added or subtracted to create an equation in one variable when using the elimination method. When two variables' coefficients are in opposition to one another, you add the equations to eliminate that variable, and when they are equal, you subtract the equations to do the same.

Let the time taken for plan A be x

and the time taken for plan B be y

Then the equation forms

Wednesday = 5x + 3y = 9 hours

Thursday = 2x + 12y =  9 hours

Lets solve this with elimination method

5(2x + 12y = 9 hours)

-2(5x + 3y = 9 hours)

⇒ 10x + 60y = 45 hours    

  -(10x + 6y = 18 hours)

     0 + 54y = 27 hours

⇒ y = 27/54 hours

   y = 1/2 hours

   y = 30 mins

Substituting the value of y in 2x + 12y =  9 hours,

2x + 12(0.5)=  9 hours

2x + 6 = 9 hours

2x = 3 hours

x = 3/2 hours

x = 1 hour 30 mins

Thus, the workout plan A lasts 1 hour and 30 mins and the workout plans B last around 30 mins only.

The probability that among 4 randomly selected Internet​ users, at least one is more careful is 0.988.

Because of the bias toward convenience when retrieving the sample, the outcome might be higher. because respondents to the survey were chosen voluntarily, not at random.

Calculating the likelihood of an event occurring, which is represented as a number between 1 and 0, is the subject of the mathematical branch known as probability. A coin toss, for instance, has a probability of 1 because, assuming the coin lands flat, there are only two possible outcomes: "heads" or "tails."

This means that any event with this probability is guaranteed to occur. For instance, a coin toss has an equal chance of coming up "heads" or "tails," so an event with a probability of.5 can be regarded as having equal odds of happening or not happening.

According to the poll, 67​% of Internet users are more careful about personal information when using a public​ Wi-Fi hotspot.

Which means the probability of more careful is 0.67

And probability of not careful is: 1-0.67 = 0.33

We have selected four random Internet​ users and we need to find the probability that at least one is more careful about personal information.

P(At least one careful) = 1 - P(None of them careful)

P(At least one careful) = 1 - (0.33×0.33×0.33×0.33)

P(At least one careful) = 1 - 0.012

Step-by-step explanation:

Hello!

First, let's find out how much the cost went up:

The cost went up by 24 dollars. To find the markup, we have to see what percentage of 45 is 24.

The markup is 53.33 percent.

The value of the following composite function is as follows:

The composite functions can be solved as follows:

Therefore, the given function are:

f(x) = x² - x

g(x) = 3x + 9

Hence,

a.

(f + g)(-2) = f(-2) + g(-2)

f(-2) + g(-2) = (2)² - 2 + 3(-2) + 9

f(-2) + g(-2) = 4 - 2 - 6 + 9

f(-2) + g(-2) = 5

Therefore, the function (f + g)(-2) = 5

b.

(f - g)(-2) =  f(-2) - g(-2)

f(-2) - g(-2) = (2)² - 2 -  (3(-2) + 9)

f(-2) - g(-2) = 4 - 2 - 3

f(-2) - g(-2) = -5

Therefore, the function (f - g)(-2) = - 5

c.

(fg)(-2)= f(-2) × g(-2)

f(-2) × g(-2) = (-2)² - (-2) ×  3(-2) + 9

f(-2) × g(-2) = 4 + 2 × 3

f(-2) × g(-2) = 6 × 3

f(-2) × g(-2) = 18

Therefore, the function (fg)(-2) = 18

d.

(f/g)(-2) = f(-2) / g(-2)

f(-2) / g(-2) = -2² - -2 / 3(-2) + 9

f(-2) / g(-2) = 6 / 3

f(-2) / g(-2) = 2

Therefore, the function (f/g)(-2) = 2
