Find f^-1(x) of f(x)=2x-3

Answers

Answer 1

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

So, the inverse function f^-1(x) of f(x) = 2x - 3 is:

f^-1(x) = (x+3)/2

This is the inverse of the function, and it can be denoted by f^-1(x) = (x+3)/2

Answer:

74 pesos

Step-by-step explanation:

Let us assume the one peso coins be x

so, number of five peso would be x + 4

And, the total coins is 22

Now the equation is

x + x + 4 = 22

2x + 4 = 22

2x = 22 - 4

2x = 18

x = 9

Five peso coins is 9 + 4 = 13

Now

= 9(1) + 13(5)

= 9 + 65

= 74 pesos

B.11k + 16

C.7k + 1k + 16

D.27k

Answers

Answer:

B. 11k + 16

Step-by-step explanation:

We have an expression and are asked to combine like terms.

To solve this, we need to first distribute 4(k + 4). Which is to multiply four by both k and 4.

(4(k) + 4(4))

4k + 16

7k + 4k + 16.

Since 7k and 4k are like terms since they end in the same variable, we can only add them.

7 + 4

11k + 16

In A x=64 bc alternate interior angles are congruent and 128/2= 64. In B x=75 bc alternate exterior angles are also congruent and (151-1)/2 = 75. In C x=12 bc consecutive interior angles are supplementary. 7x+24+72=180 180-72-24=84 84/7=12

Can someone please help me with this question?

Answers

Answer:

110 degrees

Step-by-step explanation:

Ok so no matter what the shape is, the exterior angles always have to add up to 360 degrees. Then, you can make the equation:

140 + 110 + x = 360

250 + x = 360

x = 110 degrees

Here's another way you can do it:

To do this, you can start by noticing that the top angle would be 40 degrees, because there's a straight line with 140 degrees and that angle, so you can do 180 - 140 = 40 degrees.

Then, the angle towards the bottom right would be 70 degrees using the same strategy:

180 - 110 = 70 degrees

The interior angles of a triangle always have to add up to 180 degrees, so you can do 180 - 40 - 70 = 70 to find the third interior angle of the triangle.

The last step is to do 180 - 70 = 110 to find the measure of the exterior angle at that point.

Step-by-step explanation:

For given expression x + 3 + 7x,

a) the number of terms in an algebraic expression = 2

b) the numerical coefficient of the first term = 1

c) the constant term = 3

d) the like terms are x and 7x

What is an algebraic expression?

"It is a mathematical expression that consists of variables, numbers and operations."

What is constant?

"It is a value or number that never changes in expression."

What are like terms?

"The like terms are defined as the terms that contain the same variable which is raised to the same power."

For given example,

We have been given an expression x + 3 + 7x

a) x + 3 + 7x = 3 + (1 + 7)x

= 3 + 8x

So, the number of terms in the algebraic expression = 2

b) for given expression x + 3 + 7x,

the first term is x

x = (1) × (x)

the numerical coefficient of the first term is 1.

c) for given expression x + 3 + 7x,

the constant term = 3

d) for given expression x + 3 + 7x,

the like terms are x and 7x

The weather is a common conversation for many people each day. The weather can change day-to-day or even from hour-to-hour. On the other hand, the climate in an area usually takes a long time tochange. It is the average temperature and conditions in a specific place over a long period of time, inyears. Climate does not change day-to-day or even month-to-month, but usually takes hundreds,thousands, or millions of years to change. The Earth is about 4. 5 billion years old, and during its life, the climate has changed quite oftenand has experienced an Ice Age, warming, and everything in between. All scientists agree that theclimate changed often during the first 4. 5 billion yoprs. However, it is also a proven fact that the Earth'saverage temperature has increased about 1. 33F over the past 100 years between the 1900s and 2000s. Reviewing the past 200 years it has increased about 1. 8F. It may not sound like a big change, but itwill influence the Earth.
