Ian wants to ride his bicycle 36.5 miles this week he has already written 8 miles if he rides for five more days which equation could be used to determine M the average number of miles he would have to ride to meet his goal?

Answers

Answer:

M = (36.5-8)/5

[M = 5.7 miles/day]

Step-by-step explanation:

The goal is 36.5 miles.  The remaining miles needed to achieve this goal is reduced by the miles already ridden, 8 miles.

(36.5 - 8) = 28.5 miles remaining.

We are asked to find a value for M, which is the average number of miles Ian would have to ride to reach his goal.  By average, we can assume it is the average miles/days remaining.  The days remaining are 5, so we have:

(28.5 miles remaining)/5 days = 5.7 miles/day

An equation for M using these steps would be:

M = (36.5-8)/5

How do you tell if a table represents a linear function?

Answers

If the rate of the change in the input to the change in the output is the same for every point in the table, then the table represents a linear function.

If a table of values shows a constant rate of change, it is linear.

A non-vertical graph that is a straight line is linear. An equation that can be written in the form y=mx+b is linear. If a table of values shows a constant rate of change, it is linear.

Linear relationships can be modeled using the slope-intercept form y=mx+b, As x increases, y increases by a proportional amount.

A linear function is a linear relationship that obeys the rules of a function and has a graph that forms a straight line. Function notation is used to express a linear relationship when there are clearly defined inputs and outputs.

Answers

Answer: $20.95

Due to credit rating being fair:

Secured APR = 7.00%

Loan amount = sale price + tax - down payment

New car  =  [tex]19027 + (19072 x 0.045) - 1200 = 18730.24[/tex]

Used car = [tex]15635 + (15635 x 0.045) - 1200 = 15138.575[/tex]

An art museum installed a large triangular sculpture. One of the sculpture’s exterior angles creates a 158 angle with the ground.
If the sculpture’s opposite interior angle is 32 less than the interior non-adjacent angle, what is the measure of the interior non-adjacent angle?

Answers

The measure of the interior non-adjacent angle as required in the task content is; 95°.

What is the measure of the interior non-adjacent angle?

Recall; It follows from the triangle exterior angle theorem that the measure of exterior angle of a triangle is equal to the sum of the two opposite interiors angles.

On this note, if the sculpture’s opposite interior angle is 32 less than the interior non-adjacent angle, the sum of the two angle measures is therefore;

x + x - 32.

where, x is the measure of the interior non-adjacent angle.

Hence, x + x - 32 = 158

2x = 158 + 32

2x = 190

x = 95°.

Ultimately, the measure of the interior non-adjacent angle is; 95°.

A binomial is an algebraic expression with two terms. For example, a + b, x - y, etc are binomials. We have a set of algebraic identities to find the expansion when a binomial is raised to exponents 2 and 3.

A polynomial with just terms is a binomial. An illustration of a binomial is x + 2, where x and 2 are two distinct words. Additionally, in this case, x has a coefficient of 1, an exponent of 1, and a constant of 2. As a result, a binomial is a two-term algebraic statement that comprises a constant, exponents, a variable, and a coefficient.

Which graph correctly represents the inequality?

We want to see which graph represents the inequality:

3x + y > 7

We can rewrite the inequality in slope-intercept form as:

y > -3x + 7

So we just need to graph the line:

y = -3x + 7

With a dashed line, and then shade all the region above the line.

To graph the line, you need to find two points that lie on the line.

if we evaluate the line in x = 0 we wll get:

y = -3*0 + 7

y = 7

if x = 1

y = -3*1 + 7

y = -4

Then we have the points (0, -7) and (1, -4), now we can graph these two points and connect them with a dashed line, then shade the region above.

Answers

As per the following diagram, the angle measures of triangle EFC is 118°

The term angle in math is known as a figure which is formed by two rays or lines that shares a common endpoint.

Here we have given that an artist uses colored tape to divide sections of a mural and she needs to cut a piece of paper to cover triangle EFC while she works on other sections.

According to the diagram, here we know that the value of

And the value of

Here we know that the value of the angles,

=> ∠EDB = ∠EFB = 90°

Thus implies that the angles,

=> ∠DFB = ∠FEB = 31°

Then the value of the angle is calculated as,

=> ∠EDB =∠EFB = 90° - 31°

=> ∠EDB = ∠EFB = 59°

Then the value of the angle ABC is calculated by sum the values of the angles, then we get,

=> ∠ABC = ∠EDB + ∠EFB = 59 + 59 = 118°

Answers

Answer: Yes, after 7 weeks, they will have the same amount of money

Step-by-step explanation: So let’s say Joyce will be equation 1, so it would be - T = 13 + 6x, where T represents the total money, and x represents the number of weeks. And let’s say Enrique will be equation 2, which will be - T = 80 - 5x, where once again, T represents the total money, and x represents the number of weeks.

So, let’s start going off numbers, we will start at 5 weeks, when we put that in, Joyce will have $43 and Enrique will have $65, so we know it will be more than 5 weeks, so let’s try 8 weeks, Joyce will have $61 and Enrique will have $40, so it’s below 8, so how about we try 7, at 7 weeks, Joyce will have $55, and Enrique will have $55 too. So this means, after 7 weeks, Joyce and Enrique will have the same amount of money

f(x) =(x - 5)/3 find the inverse function of this

Answers

The inverse function of f(x) = (x - 5)/3 is f^-1(x) = 3x + 5.

What is inverse function? How to calculate it? In mathematics, an inverse function is a function that undoes the work of another function. Specifically, if the function f applied to an input x gives a result of y, then the inverse function of f, denoted as f−1, applied to y gives the result x. In other words, the inverse of the function "f" applied to y will give us the input that we originally used to obtain y.To calculate an inverse function, one must first identify the original function. Then, one must switch the x and y variables, and solve for y. This is done by isolating the y in the equation and replacing it with the inverse function. For example, if the original equation is y = x + 4, then the inverse equation is x = y - 4.Once this is done, one can then determine the inverse function by taking the reciprocal of the function. This can be done by changing the sign of the exponent for any exponentiated terms and changing the sign of the coefficient for any multiplied terms. For example, if the function is y = x2 + 2x + 4, then the inverse function is y = (1/x2 + 2/x + 4)−1.In summary, to calculate an inverse function, one must first identify the original function, switch x and y, and solve for y, and then take the reciprocal of the expression.

Solution:

To find the inverse of a function, we need to switch the x and y variables, and then solve for y.

Starting with f(x) = (x - 5)/3, we can switch the x and y variables to get y = (x - 5)/3.

We can then solve for x by multiplying both sides by 3, giving us 3y = x - 5.

We can then add 5 to both sides to get 3y + 5 = x, which is the inverse of our original function.

Therefore, the inverse of f(x) = (x - 5)/3 is f^-1(x) = 3x + 5.

First, the fact that a 2 was rolled before does not affect the next rolls of the dice, so that information is extra.

Now we just need to see which option has the largest probability.

A) There are only one number lower than 2, then the probability of this event is p = 1/6

B) There are 3 numbers higher than 2, then the probability is p = 3/6 = 1/2

We can see that the event with the largest probability is B, so that one is the most likely to occur.
