Solve for x: (1 point) negative 9 over 8, multiplied by x minus 7 equals negative 25

Answer:

3x + 4

.................

The factor 3x + 4 have common in both the given expressions.

A whole number that is a factor of two or more numbers is referred to as a common factor. The largest factor that will divide into two or more numbers is known as the highest common factor (HCF). The smallest multiple shared by two or more numbers is known as the lowest common multiple (LCM).

The given expressions are,

[tex]9x^2 + 24x + 16, 9x^2 - 16[/tex]

The expression [tex]9x^2 + 24x + 16[/tex] is of the form [tex](a + b)^2[/tex]

where [tex]a = 3x , b = 4[/tex]

Therefore,   [tex]9x^2 + 24x + 16 = (3x + 4)^2.[/tex]

The expression [tex]9x^2 - 16[/tex]   is of the form [tex]a^2 - b^2[/tex].

It can be written as, [tex]a^2 - b^2 = (a - b)(a + b)[/tex]

Here, [tex]a = 3x , b = 4[/tex]

Therefore,

[tex]9x^2 - 16 = (3x - 4)(3x + 4)[/tex]

So, in both the expressions the factor (3x + 4) is common.

Answer:

7.071068 ≈ 7.07

Step-by-step explanation:

The distance, d,  between 2 points (x1, y1) and (x2, y2) is given by the formula

[tex]d = \sqrt {(x_{2} - x_{1})^2 + (y_{2} - y_{1})^2}[/tex]

The two points as determined from the graph are (1, 5) and (2, -2)

[tex]d = \sqrt {(2 - 1)^2 + (-2 - 5)^2}[/tex]

[tex]d = \sqrt {(1)^2 + (-7)^2}[/tex]

[tex]d = \sqrt {{1} + {49}}[/tex]

[tex]d = \sqrt {50}[/tex]

[tex]d = 7.071068[/tex]

The least common multiple of 32, 48, and 16 is 96

The first step is to get the prime factors of each number

The prime factors of 32 are 2, 2, 2, 2 and 2.

The prime factors of 48 are  2, 2, 2, 2 and 3

The prime factors of 16 are 2,2,2 and 2

The least common multiple of 32, 48 and 16 can be calculated as follows

2 × 2 × 2 × 2 × 2 × 3

= 32 × 3

= 96

Hence the least common multiple of 32, 48, and 16 is 96

Step-by-step explanation:

The total cost of painting per cm will be 45.2% i.e. option(d).

Total cost of painting = Rate × Surface area of sphere

We know the radius is increases by 10%.

Thus, the Surface area will change by 21%

The total change in cost of painting will be

= 20+21 +(20x21)/100

= 45.2%.

In the picture, there is a square and a shaded region inside the square. The shaded portion has a 13.76 square meter area.

Given that,

In the picture, there is a square and a shaded region inside the square.

We have to find the shaded portion area.

The side of the square is 8cm.

Now,

First we see the unshaded region on the square is there are 4 unshaded regions.

In the figure u can see there is a unshaded region we named that has tile 1, tile2, tile 3, and tile 4.

If we restock them we can see that we got a circle with that 4 tiles.

Now, the side is 8 cm then the 1 tile will be of 4 cm.

So, the radius of the circle is 4 cm.

In the other picture we can see that the area of the shaded region is equal to area of square- area of circle.

Area of the shaded region =s²-πr²

Area of the shaded region =8²-π(4)²

Area of the shaded region =64-π(16)

Area of the shaded region =64-16π

Area of the shaded region =64-16(3.14)

Area of the shaded region =64-50.24

Area of the shaded region =13.76

Pairs of values that could be the number of grams of protein and fiber in the protein bar are:

10 grams of protein and 20 grams of fiber. That is, (10, 20)

and

15 grams of protein and 10 grams of fiber. That is, (15, 10)

From the question, we are to determine the pair of values that could be the number of grams of protein and fiber in the protein bar

From the given information,

The protein has 80 calories from p grams of protein and f grams of fiber

and

The equation that represents the relationship is

4p + 2f = 80

To determine the pair of values, we can determine the values of f for certain values of p

When p = 10

4p + 2f = 80

4(10) + 2f = 80

40 + 2f = 80

2f = 80 - 40

2f = 40

f = 40/2

f = 20

A pair of values is 10 grams of protein and 20 grams of fiber.

When p = 15

4p + 2f = 80

4(15) + 2f = 80

60 + 2f = 80

2f = 80 - 60

2f = 20

f = 20/2

f = 10

A statement which best describes the meaning of function f(150) is that: A. This is the average number of days the house stayed on the market before being sold for $150,000.

The average rate of change can be defined as a type of function that is used for describing the average rate at which a quantity either decreases or increases with respect to another quantity.

A function simply refers to a mathematical expression which is used to define and represent the relationship that exists between two or more variables. This ultimately implies that, a function is typically used for mapping an input variable (x-value) to an output variable (y-value or f(x)).

In this scenario, the function f(150) can be evaluated as follows:

Function f(150) = 150 × p

Function f(150) = 150 × $1,000.

Function f(150) = $150,000

Therefore, the function f(150) simply means the average number of days this house stayed on the market before it was then sold for $150,000.

Answer:

Step-by-step explanation:

The properties of the function are:

The absolute value equation of the function is given as

y = |x|

On the incomplete table of values, we do not have any x values

So, we can make use of any x value

To do this, we make use of the following x values

x = -3, -1, 0, 1 and 3

Next, we substitute x = -3, -1, 0, 1 and 3 in the equation y = |x|

So, we have:

y = |-3| = 3

y = |-1| = 1

y = |0| = 0

y = |1| = 1

y = |3| = 3

When represented on a table of values, we  have

x | y

-3 | 3

-1 | 1

0 | 0

1 | 1

3 | 3

Using rotation rules, considering the 90º clockwise rotation, the coordinates of point A are given as follows:

(-2,0).

The origin has coordinates (0,0), hence the rule for a 90º clockwise rotation about the origin is:

(x,y) -> (y, -x).

Considering a point (xP, yP) as reference, the rule for the coordinates of the vertices after the rotation is given as follows:

(x,y) -> (y - yP, -x + xP).

For this problem, point B is the reference point, hence the reference coordinates are as follows:

xP = 2, yP = 1.

Then the rule is:

(x, y) -> (y - 1, -x + 2).

Point A is located at:

x = -2, y = -1.

After the rotation, the coordinates will be given as follows:

(x, y) -> (-1 - 1, -2 + 2) = (-2,0).
