Answer:

b)  [tex]4x^2-12x+9=0[/tex]

Step-by-step explanation:

We can use the discriminant [tex]b^2-4ac[/tex] to determine how many real solutions a quadratic equation in the form [tex]ax^2+bx+c=0[/tex] has.

[tex]5x^2+9x-4=0[/tex]

[tex]b^2-4ac=9^2-4(5)(-4)=161 > 0\implies \textsf{2 solutions}[/tex]

[tex]4x^2-12x+9=0[/tex]

[tex]b^2-4ac=(-12)^2-4(4)(9)=0 \implies \textsf{1 solution}[/tex]

[tex]-9x^2+6x+1=0[/tex]

[tex]b^2-4ac=6^2-4(-9)(1)=72 > 0 \implies \textsf{2 solutions}[/tex]

[tex]-2x^2-7=0[/tex]

[tex]b^2-4ac=0^2-4(-2)(-7)=-56 < 0 \implies \textsf{no solutions}[/tex]

Answer:

$134.40

Step-by-step explanation:

The markup is 28% of 105, or .28(105) = $29.40

Thus the retail price is $105 + $29.40 = $134.40

The price of the bookcase in the furniture store, after a 28% markup on the wholesale price, is $134.40.

To find the price of the bookcase in the furniture store after a 28% markup on the wholesale price, we need to add the markup amount to the wholesale price.

The markup amount is calculated by multiplying the wholesale price by the markup percentage (expressed as a decimal). In this case, the markup percentage is 28%, which is equivalent to 0.28 as a decimal.

Markup amount = Wholesale price * Markup percentage

Markup amount = $105 * 0.28

Markup amount = $29.40

Now, to find the price of the bookcase in the furniture store, we add the markup amount to the wholesale price:

Price in the furniture store = Wholesale price + Markup amount

Price in the furniture store = $105 + $29.40

Price in the furniture store = $134.40

Answer:

The sequence of transformations involved is a reflection across the x axis, followed by a reflection across the y = x line

Step-by-step explanation:

The polygon ABCD is shown in the image attached. The coordinates of the polygon are A(-6, 6), B(-4, 6), C(-4, 4), D(-6, 2), while the polygon A'B'C'D' is at A'(-6, -6), B'(-6, -4), C'(-4, -4), D'(-2, -6)

A transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, translation, dilation and rotation.

If a point O(x, y) is reflected across the x axis, the new coordinate is O'(x, -y).

If a point O(x, y) is reflected across the y = x line, the new coordinate is O'(y, x)

Hence if polygon ABCD is reflected across the x axis, the new coordinates are A*(-6, -6), B*(-4, -6), C*(-4, -4), D*(-6, -2). If a reflection across the y = x line, the new coordinates are A'(-6, -6), B'(-6, -4), C'(-4, -4), D'(-2, -6)

Answer:

Polygon ABCD goes through a sequence of rigid transformations to form polygon A′B′C′D′. The sequence of transformations involved is a reflection across the y-axisy = -x, followed by a reflection across the line y = xy = -x.

Answer:

4 Hours and 32 minutes

Step-by-step explanation:

Let's first find the amount between 9:15 to 2:17

The difference between 9:00 and 2: 00 is 5 Hours

Now the minutes ->  17-15 = 2

Thus, the difference is 5 Hour and 2 Minutes

Then She took a 30 minutes break for lunch.

Let's convent all to minutes:

1 Hour = 60

Then 60  x 5  = 300

Plus the 2 minutes is

302

Now 302 minutes - 30 minutes = 272 minutes

Now convent back to Hour

Thus, 272/60 =4 with a remainder of 32.

Hence, it took stephanie 4 hour and 32 minutes to finish her SOL test.

An absolute value function, which when graphed, represents the parent function, f(x) = |x|, reflected over the x-axis and translated 1 unit to the right include the following: B. f(x) = –|x – 1|.

In Mathematics, a reflection across or over the x-axis would maintain the same x-coordinate while the sign of the y-coordinate would either change from positive to negative or negative to positive.

This ultimately implies that, a reflection across the x-axis is given by this transformation rule: (x, y)  →  (x, -y).

By applying a reflection across or over the x-axis to the function, we have the following;

f(x) = -|x|

-f(x)' = |x|

f(x)' = -|x|

Next, we would translate the function to the right by 1 unit as follows;

f(x)' = -|x - 1|

Step-by-step explanation:

Answer:

25x5-4=b

Step-by-step explanation:

The equation to determine the number of baseball cards in Shaun's collection is b = (25 - 4) × 9

Number of pages in the album = 25 pages

Number of empty pages = 4

Number of full pages = 25 pages - 4 pages = 21 pages.

Number of cards that each page can hold = 9 cards.

Therefore, the equation to determine the number of baseball cards in Shaun's collection will be:

b = (25 - 4) × 9

b = 21 × 9

b = 189 cards.

There are 189 cards in the collection.

Answer:

see explanation

Step-by-step explanation:

The figure has one pair of parallel sides and is a trapezoid.

Each lower base angle is supplementary to the upper base angle on the same side, thus

15x + 30 + 10x = 180 , that is

25x + 30 = 180 ( subtract 30 from both sides )

25x = 150 ( divide both sides by 25 )

x = 6

Also

3y + 18 + 90 = 180 , that is

3y + 108 = 180 ( subtract 108 from both sides )

3y = 72 ( divide both sides by 3 )

y = 24

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

2x, 90 and x lie on a straight line and sum to 180 , thus

2x + 90 + x = 180 , that is

3x + 90 = 180 ( subtract 90 from both sides )

3x = 90 ( divide both sides by 3 )

x = 30

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

2y and x are alternate angles and congruent , thus

2y = x = 30 ( divide both sides by 2 )

y = 15
