To find the inverse of f(x) = 2x - 1, Patel begins by replacing f(x) with y. He
then switches x and y. What is the next step?
O A. Solve the equation for y.
O B. Solve the equation for x.
C. Subtract 1 from both sides of the equation.
D. Replace y with f1(x).

Answers

Answer 1

Answer:A

Step-by-step explanation:

Answer 2

The inverse of the function is y = (x +1) /2, the next step is to solve the equation for y, the correct option is A.

What is a Function?

A function is a law that relates two variables namely, a dependent and an independent variable.

A function always has a defined range and domain, domain is all the value a function can have as an input and range is all the value that a function can have.

The function is f(x) = 2x -1

The inverse of a function is determined by interchanging the variables x and y and then solving for y in terms of x.

Patel replaced f(x) by y, y = 2x -1

He then switched  x and y, x = 2y -1

The next step is to solve the equation for y.

2y = x +1

y = (x +1) /2

Answer:

12/7 possibly.

Step-by-step explanation:

Point C is (0,0) and point D is (7,12). Using the formula given, You should have something that looks like this:

[tex]\frac{(12-0)}{(7-0)}[/tex]

Then you solve:

Two angles form a linear pair. The measure of one angle is 1/3 of the other angle. Find the measure if each angle

Answers

Answer:

The measure of the angles is 45° and 135°

Step-by-step explanation:

When two lines intersect, a linear pair of angles is formed. Two angles are said to be linear if they are adjacent, so a linear pair of angles must add up to 180 degrees.

Let's call x and y the two required angles. Knowing they form a linear pair:

x+y=180

We also know one angle is 1/3 of the other angle, thus:

x=y/3

Or, equivalently:

3x=y

Substituting y into the first equation:

x+3x=180

Simplifying:

4x=180

Solving:

x=180/4=45

The other angle is:

y=3x=3\cdot 45=135

Thus the measure of the angles is 45° and 135°

Lionel plays trumpet for a minimum of 45 minutes on the days that he practices. If x is the number of days that Lionel practices and y is the total number of hours he spends practicing, what would the inequality be?

Answers

The inequality is  0.75x greater than or equal to y

Step-by-step explanation:

Given : Lionel plays trumpet for a minimum of 45 minutes on the days that he practices. If x is the number of days that Lionel practices and y is the total number of hours he spends practicing.

To find : Which inequality represents this situation?

Solution :  He plays trumpet for a minimum of 45 minutes

If x is the number of days that Lionel practices then he practices for at least  

hours

y is the total number of hours he spends practicing

So, the inequality form is:

a cookie recipe uses 5/6 cups of sugar lindsey is making 1 1/2 times what the recipe calls for how much sugar is she using

Answers

Answer:

1 1/4 cups of sugar

Step-by-step explanation:

5/6 x 1 1/2 = 1 1/4

Answer:

5/4 cup of sugar.

Step-by-step explanation:

The recipe calls for 5/6 of a cup of sugar, so if you're making 1.5 times what the recipe calls for, you multiply 5/6 by 3/2 (or 1.5 if you prefer decimals) which would give you 15/12. Then simplify down to get 5/4 (or 1.25) cups of sugar.

Note: 5/4 also equals 1 1/4, they are both correct, it just depends on which way you choose to write it, or how your teacher wants you to write it.

*see attachment below for the figure referred to

Answer:

*The measure of angle <CBA is equal to the measure of angle <DBE.

*The measure of angle CBD is equal to the measure of angle ABE.

*The sum of the measures of angles CBD and CBA is 180 degrees.

Step-by-step explanation:

Since lines CE and AD bisects at D, they form two pairs of vertical angles that are congruent to each other. The vertical angle pairs formed are:

<CBD and <ABE;

<CBA and <DBE

Thus:

m<CBD = m<ABE;

m<CBA = <DBE = 37°

Also, m<CBA + m<CBD = 180° (supplementary linear pair)

m<ABE + m<DBE = 180° (supplementary linear pair)

Therefore, the following statements are TRUE:

*The measure of angle <CBA is equal to the measure of angle <DBE.

*The measure of angle CBD is equal to the measure of angle ABE.

*The sum of the measures of angles CBD and CBA is 180 degrees.

Solve for x2:

y2 − y1 = m(x2 − x1)


this is literal equations btw

Answers

Answer:

x2 = y2/m - y1/m + x1

Step-by-step explanation:

Expand

y2 - y1 = mx2 - mx1

Rearrange

y2 - y1 + mx1 = mx2

Divide both sides by m to make x2 on its own

y2/m - y1/m + x1 (m's cancel out) = x2

Hence:

x2 = y2/m - y1/m + x1

Answer:

x2 = x1 +  (y2 - y1)/m

Step-by-step explanation:

Given equation

y2 − y1 = m(x2 − x1)

Solving for x2

y2 − y1 = m(x2 − x1)  ⇒ divide both sides by m(y2 - y1)/m = x2 - x1  ⇒ add x1 to both sidesx2 = x1 +  (y2 - y1)/m

or

x2 = x1 + y2/m - y1/m

Summarize this up into one sentence. There's been a great debate among amongst historians for a very long time about the relative status of black men and women and poor white men and women in the period before 1660 in Virginia. It was once assumed that blacks were slaves for life, and whites were servants for 3, 4, 5, 7 years, depending on the contract. That was that. But the more people delved into the records, they found that, in fact, these statuses were not at all clear. Some blacks were slaves for life. Some seem to have been servants. Some seem to have achieved a freedom of some sort, of very various degrees of dependency on former masters and patrons and whatnot. Servants were in these contracts. They seem to have been treated dreadfully, and in some ways maybe even worse than some of the blacks, because as their contracts ran out, [they were] almost -- I don't want to be vulgar -- but treated like cars that you might rent, and you know that you you're going to run out on the contract. In any case, the experience of these whites was terrible.My point is that in the early years of Virginia, these kinds of statuses were unclear, even to the people that were alive then. There was a range of possibilities. And you would certainly not assume that just simply because a man or woman was an African American, that he or she was a slave.Now, if we turned forward a century into the 18th century you find a hardening of these kinds of categories. The racial assumptions are there. A man's skin determines his status. But that was not true in the early years.(50 points) The cartoon depicts various politicians pulling at different sections of the US map. Why does this represent sectionalism?
