Answer:

Option A is the correct answer. ; x=-2/3 and x=3/2

Step-by-step explanation:

We have been given that p(x)=(3x+2)(2x−3) is a polynomial.

According to the question's statement, Question asks us to find the zeros of the polynomial.

Let's head to the question in order to get required answer.

p(x)=(3x+2)(2x−3)

=> p(x) = 3x(2x-3) + 2(2x-3)

=> p(x) = 6x² - 9x + 4x - 6

=> p(x) = 6x² - 5x - 6 (This is the standard form for the given polynomial)

Now, We need to find the zeros of the polynomial. So, In order to find its zeros, we need to put p(x).

p(x) = (3x+2)(2x-3)

=> 0 = (3x+2)(2x-3)

=> (3x+2) = 0 or (2x-3) = 0

=> x= -2/3 or x = 3/2

Hence, If p(x)=(3x+2)(2x−3), x = -2/3 & x= 3/2 are the zeros of the polynomial.

Answer: Reflexive property of equality

This property says that any expression is equal to itself.

Answer:

-7/(x-5) - 3

Step-by-step explanation:

First off, to reflect an equation in the y axis, just multiply by -1. Now that it is reflected, to stretch an equation by a factor of 7, multiply it by 7. Now we have -7/x.

Then, to move an equation down by 3 units, simply subtract it by 3. Now we have -7/x - 3.

Lastly, since you want to translate it 5 units to the left, you want the equation to be undefined at x = 5 (because originally it is undefined at x = 0). To do that, set the denominator to x - 5. We arrive at our answer: -7/(x-5) - 3.

Using translation concepts, it is found that the new definition for the function is:

[tex]g(x) = -\frac{7}{x - 5} - 3[/tex]

----------------------------

The parent function is:

[tex]f(x) = \frac{1}{x}[/tex]

[tex]g(x) = 7 \times \frac{1}{x} = \frac{7}{x}[/tex]

[tex]g(-x) = \frac{7}{-x} = -\frac{7}{x}[/tex]

[tex]g(x) = -\frac{7}{x - 5}[/tex]

[tex]g(x) = -\frac{7}{x - 5} - 3[/tex]

Answer:

x = 2

Step-by-step explanation:

2(3х + 5) = 22

Divide both sides by 2.

3x + 5 = 11

Subtract 5 from both sides.

3x = 6

Divide both sides by 3.

x = 2

Answer:

Step-by-step explanation:

Number of days = y

Number of weeks = x

1 week = 7days

Formula = 7x = y

13 weeks = 7(13) = 91 days

29 weeks = 7(29) = 203 days

7.5 weeks = 7(7.5) = 52.5 days

Answer:

  multiply the magnitudes of the numbers; affix a negative sign.

Step-by-step explanation:

The product of a positive number and a negative number is the negative of the product of their numerical values.

For example, ...

  (2)(-3) = -(2×3) = -6

  (-2)(3) = -(2×3) = -6

Answer:

Whenever you multiply two numbers with different signs, the answer is always NEGATIVE.

Answer:

Let's name the angle right close to 51 as c.

c = 180°-51° since angles on a straight line is equal to 180°.

so c= 129°

so x = 129° since it corresponds to c

Answer:

Step-by-step explanation:

Notice that the line that the variable x is on is equal to 180 degrees. Because the angle that it is next to is equal to 51 degrees, you subtract 180 from 51:

180-51=129

The final answer to this problem is 129 degrees.

Step-by-step explanation:

let the unknown be x

length = x

width = 3.6 cm

Perimeter = 2 lengths + 2 widths

48 cm = x + x + 3.6 + 3.6

48 cm = 2x + 7.2

40.8 = 2x

20.4 cm = x

if you wanna check,

perimeter = 20.4 + 20.4 + 3.6 + 3.6

48 cm = 48

Using the relationship between the dimension of a rectangle and its perimeter, given its perimeter and width, the length is: 20.4 cm.

Recall:

Perimeter of a rectangle (P) = 2(L + W) (relationship between the width, length and perimeter)

Given:

Using the relationship between the dimension of a rectangle and its perimeter, the following equation would be derived:

48 = 2(L + 3.6)

48 = 2L + 7.2

48 - 7.2 = 2L

40.8 = 2L

20.4 = L

L = 20.4 cm

Therefore, using the relationship between the dimension of a rectangle and its perimeter, given its perimeter and width, the length is: 20.4 cm.
