If c (x) = 5 Over x minus 2 and d(x) = x + 3, what is the domain of (cd)(x)?

Answers

Answer 1

The domain of the function (cd)(x) will be all real values of x except x = 2.

Step-by-step explanation:

The two functions are c(x)=

[tex] \frac{5}{ \times - 2} [/tex]

and d(x) = x + 3

So, (cd)(x) =

[tex]( \frac{5}{ \times - 2} )( \times + 3) = 5\frac{( \times + 3)}{ \times - 2} [/tex]

Therefore, the domain of the function (cd)(x) will be all real values of x except x = 2. (Answer)

Step-by-step explanation:

To obtain the inverse, rearrange the relation making x the subject

y = x² + 4 ( subtract 4 from both sides )

y - 4 = x² , or

x² = y - 4 ( take square root of both sides )

x = ± [tex]\sqrt{y-4}[/tex]

Change y into terms of x with x = [tex]f^{-1}[/tex] (x) , that is

F(x) = 8x+7 If f(x)=31 find x

Answers

Answer: x = 3

Step-by-step explanation:

Let's solve your equation step-by-step.

31 = 8x + 7

Step 1: Flip the equation.

8x + 7 = 31

Step 2: Subtract 7 from both sides.

8x + 7 − 7 = 31 − 7

8x = 24

Step 3: Divide both sides by 8.

8x /8  =  24 /8

x = 3

Answer:

x = 3

at a zoo, 3 pandas eat a total of 181 1/2 pounds of bamboo shoots each day. The male panda eats 3 times as much as the baby. The female eats twice as much as the baby. How many pounds of bamboo shoots does the female panda eat? Steps

Answers

The female panda eats 60,5 pounds of bamboo shoots.

Step by step Explanation|

Ok so in order to solve this problem we would have to create a equation. We have to be able to represent each value in the equation. And since we don’t have anymore information we can’t make them different variables, the good thing is that they are all expressed in terms of how much does the baby panda eats. So baby panda amount of food will be expressed by:
x,
and since the female panda is twice that it would be:
2x,
And since the male panda is three times that it would be:
3x,
And the totals between the 3 of them is:
181/ and 1/2,

So the sum of all of them is...
(We put it into an equation so it would look like this):
3x + 2x + x = 181 1/2
6x = 181 1/2
X = (181 1/2)/6
X = 30/25

Now since the problems asks for how much does the female panda eats, we will calculate in our heads of course that:
2x,2(30,25) = 60,5 pounds..

So the female panda eats 60,5 pounds of bamboo.

Do only equations with variables on both sides have no​ solution? Or can the variable be just on one​ side? Justify your answer. Choose the correct answer below.

A. Every equation with variables on both sides has no solution.​ However, it is also possible for an equation with the variable on only one side to also have no solution.

B. If the variable only appears on one side of an​ equation, then the equation can always be solved for the variable. This means that if an equation has no​ solution, then the variable must appear on both sides.

C. Any equation can have one​ solution, infinitely many​ solutions, or no solutions. This does not depend on whether the variable appears on only one side or on both sides.

D. If the variable only appears on one side of an​ equation, then the equation can always be solved for the variable. By​ contrast, an equation with variables on both sides always has no solution or infinitely many solutions.

Answer:

Option C

Step-by-step explanation:

A. Every equation with variables on both sides has no solution.​ However, it is also possible for an equation with the variable on only one side to also have no solution.

False, the first pat incorrect. The equation can be simplified to have variable on one side and solved further.

B. If the variable only appears on one side of an​ equation, then the equation can always be solved for the variable. This means that if an equation has no​ solution, then the variable must appear on both sides.

False, the second part is incorrect. If an equation has no solution, then variables disappear and it results in nonsense equation.

C. Any equation can have one​ solution, infinitely many​ solutions, or no solutions. This does not depend on whether the variable appears on only one side or on both sides.

True

D. If the variable only appears on one side of an​ equation, then the equation can always be solved for the variable. By​ contrast, an equation with variables on both sides always has no solution or infinitely many solutions.

False, the second part is incorrect. The variables can be taken to the same side of equation. If they cancel and leave a correct equation, then it results in infinitely many solutions. If they cancel and leave incorrect equation, then it results in no solution. If it simplifies with variable on one side, then there is one solution.

Step-by-step explanation:

The numbers 2 and 3 add to 5 and multiply to 6. Therefore when you put them in a factor box, you will end up with [tex]x^2+5x+6[/tex]

Answer : (x+3) (x+2) :

Step-1 : Multiply the coefficient of the first term by the constant 1 • 6 = 6

Step-2 : Find two factors of 6 whose sum equals the coefficient of the middle term, which is 5 .

-6 + -1 = -7
-3 + -2 = -5
-2 + -3 = -5
-1 + -6 = -7
1 + 6 = 7
2 + 3 = 5 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, 2 and 3
x2 + 2x + 3x + 6

Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x+2)
Add up the last 2 terms, pulling out common factors :
3 • (x+2)
Step-5 : Add up the four terms of step
