f(x) = x2 + 6x + 4
What is the increasing and decreasing

Answers

Answer 1

9514 1404 393

Answer:

decreasing: (-∞, -3)increasing: (-3, ∞)

Step-by-step explanation:

The leading coefficient is positive, so you know the parabola opens upward.

The ratio -b/(2a) is -6/(2·1) = -3, so you know the axis of symmetry is x = -3. The function will be decreasing from negative infinity to the vertex at x = -3, and will be increasing from there to positive infinity. At the vertex (x=-3), the function is neither increasing nor decreasing.

decreasing: (-∞, -3)increasing: (-3, ∞)

_____

Additional comment

For ax^2 +bx +c, the axis of symmetry is x=-b/(2a). The vertex (turning point) is on the axis of symmetry.

Answer:

  B.  w, t, and y

Step-by-step explanation:

Delete the numbers and the math operators and what you have left are variables. You will want to eliminate any duplicates from the list (there aren't any duplicate).

The variables are w, t, y.

Answer:

Option B

Step-by-step explanation:

Definition of variables: Variables are terms that have no coefficients.

To look for variables in the expression 2w + 11t + 4y, simply look for the variables (letters) in the expression. We can see that the variables are w, t, and y, which matches Option B.

Hence, Option B is correct.

Describe the transformation f(x) = Vx+ 1 - 5 in words.
The parent function f(x) = V has been shifted
1 unit and
5 units

Answers

Answer:

The translation is 1  unit to the left and  5 units down

Step-by-step explanation:

The explanation is given below;

Given that

The transform function is [tex]f(x) = \sqrt{x+1} - 5[/tex]

It can be seen that

The parent function is

[tex]f(x) = \sqrt{x}[/tex]

After that

The parent function would be transform 1 units to the left [tex]\sqrt{x+1}[/tex]

And afterwards it would be transform in 5 units down [tex]\sqrt{x+1} - 5[/tex]

So

The parent function [tex]f(x) = \sqrt{x}[/tex] would be  translate in 1  unit to the left and  5 units down

Answer:

The translation is 1  unit to the left and  5 units down

Olivia needs 545454 licks for every 333 lollipops she eats.

Answers

Answer:

54 lick per 3 lollipops is a unit rate of 18 licks per lollipop.

36 is 2 times 18, so it needs 2 times as many licks as 18 lollipops.

36 2

I assume the last line is 5 lollipops.

If 1 lollipop takes 18 licks, then 5 lollipops take 5 * 18 licks.

5 * 18 = 90

90 5

Answer: i think 2 because 90 divided by 5 is 18 and 54 divided by 3 is 18 so

Complete the statement by filling in the blanks. The null hypothesis H0 is the statement of _________ and always has a ______ sign. The alternative hypothesis Ha is the __________ hypothesis. It is a statement about the value of a __________ that we intend to test. Group of answer choices

Answers

Answer:

No change ; = ; research ; parameter

Step-by-step explanation:

The Null hypothesis in a statistical test is always the initial truth which always means that a research scenario or statement is as it is or that there is no change whatsoever. The null hypothesis is usually denoted as H0 ; because it is always the initial truth or accepted claim, it usually takes a equal to sign, this denotes that, there is no change in parameter, either the population mean or any other statistical measure we wish to test. The alternative hypothesis on the other hand always negated the null hypothesis, because it brings up a claim which is to check or peruse the Null hypothesis, hence, it is a research hypothesis, denoted as Ha: ;

The alternative hypothesis contains the statement about the population parameter we wish to test( parameter is a measured value about the population).

If a graph is reflected across y = x then it will be an inverse graph so graphs B and C will be inverse.

What is the inverse of a function?

The inverse of a function is basically a reverse function or undo of the function.

For example y = f(x) then inverse will be x = f(y).

It means in the inverse function we need to interchange x and y.

Another example y = 3x² ⇒ x = √(y/3) will be the inverse.

An inverse function is a reflection of graph across y = x and due to that coordinate will interchange its that ;

( x ,y ) → ( y , x )

Since graph A is rotated about the x-axis to make graph B

Now,

Graph A is rotated( which is B ) and reflected across the axis y = x to form Graph C.

So B and C will be the inverse of each other.

Hence "If a graph is reflected across y = x then it will be an inverse graph so graphs B and C will be inverse".

Answers

Answer:

C. SSS

Step-by-step explanation:

[tex] \frac{AB}{SQ} = \frac{AC}{SR} = \frac{BC}{QR} = 2 [/tex]

Thus, the ratio of the corresponding side lengths of both triangles are equal. This implies that all three corresponding side lengths of both triangles are proportional to each other.

Consequently, based on the SSS Criterion, we can conclude that both triangles are similar to each other.

use the elimination method to solve the following system of equations
2x+y=7
6x-y=9​

Answers

Answer:

x=2

Step-by-step explanation:

We see that there is already a common variable that can be canceled out -- y. y+(-y)=0! (Alternatively you may also multiply an equation by negative 1 and do subtraction, but in this case it's already done for you)

So now we just do some addition.

2x+6x=8x

y+(-y)=0

7+9=16

This means that 8x=16. Now we solve!

(Divide both sides by 8)

We're left with x=2 :)

In a dance competition, a participant has to score a total of at least 30 points in the first four rounds combined to move on to the fifth and final round. Steward scored 5 points in the first round. He then went on to score additional points in the second, third, and fourth rounds. In each of those rounds, his score was identical. Which inequality best shows the number of points, p, that Steward scored in each of the second, third, and fourth rounds if he earned a place in the finals? (1 point)

a
5 + 3p ≥ 30

b
5 + 3p ≤ 30

c
5p + 3 ≥ 30

d
5p + 3 ≤ 30

Answers

Given:

Score in first round = 5 points

Score in second, third and fourth rounds was identical.

A participant has to score a total of at least 30 points in the first four rounds combined to move on to the fifth and final round.

To find:

The inequality for the given problem.

Solution:

Let p be the number of points, p, that Steward scored in each of the second, third, and fourth rounds.

Score in first 4 rounds = Score of 1st round + Score of 2nd round + Score of  1s 3rd round + Score of 4th round

Score in first 4 rounds [tex]=5 + p + p + p[/tex]

                                     [tex]=5 +3p[/tex]

A participant has to score a total of at least 30 points in the first four rounds combined to move on to the fifth and final round. It means the total score in first 4 rounds must be greater than or equal to 30.

[tex]5+3p\geq 30[/tex]
