9 less than 2 times a number is equal to 21.

9 - 2 - n = 21

9-2n = 21

2n - 9 = 21

9n - 2 = 21

The value of f(5)  in the function are - 9 . Option B

A function can be defined as an expression, rule or law that shows the relationship between a dependent variable or independent variable.

Given the functions;

To determine the value f(5),  substitute the value of x as 5

x > 1 , so we use equation 2

From function (2)

f(5) = 1 - 2x

f(5)  = 1 - 2(5)

f(5) = 1 - 10

f(5)  = - 9

Thus, the value of f(5)  in the function are - 9 . Option B

Answer:

Below in bold.

Step-by-step explanation:

Slope = difference in y values / difference is x values

= (1 - (-3)) / (0 - (-1)

= 4 / 1

= 4.

The y-intercept is the y value when x = 0, so it is

= 1.

So, the equation is

y = 4x + 1.

The asymptotes of the graph are vertical asymptotes as; x = 0 and x = -4

The end behavior of the second graph is that as x → ∞, f(x) → -∞ and x → -∞, f(x) → -∞

An asymptote is defined as a line that a curve approaches, as it heads towards infinity. There are three types of Asymptotes namely horizontal, vertical and oblique.

It is called a Horizontal Asymptote when as x goes to positive or negative infinity the curve approaches some constant value.

It is called a Vertical Asymptote when as x approaches some constant value (from the left or right) then the curve goes towards positive or negative infinity

It is called an Oblique Asymptote when as x goes to positive or negative infinity, then the curve goes towards a line y = mx + b

Thus, the asymptotes of the graph are vertical asymptotes as;

x = 0 and x = -4

The end behavior of the second graph is that as x → ∞, f(x) → -∞ and x → -∞, f(x) → -∞

The value of x of the first rectangular deck is 8.

For given question,

The perimeter of a one rectangular deck is 78 feet.

The length of the first rectangular deck is  represented as (2x + 3), and its width is represented as (3x-4).

Similarly, the perimeter of a second rectangular deck is 2 times the perimeter of the first deck with a length of (4x + 6) and a width of (6x -1).

We need to find the value of x of the first rectangular deck.

Let P1 be the perimeter of the first rectangular deck.

⇒ P1 = 2 × (length + width)

⇒ 78 = 2 × [(2x + 3) + (3x - 4)]

⇒ 39 = (2x + 3x + 3 - 4)

⇒ 39 = 5x - 1

⇒ 40 = 5x

⇒ x = 40/5

⇒ x = 8

Therefore, the value of x of the first rectangular deck is 8.

Answer:The answer would be 11/15 mile

Step-by-step explanation:

Over the weekend she walked a total distance of (4 + 5/8) miles

We know that on Saturday she walked a total of (3 + 7/10) miles (so we need to work with mixed numbers), and on Sunday she walked 0.25 of that distance.

Then the  distance that she walked on Sunday is:

D = 0.25*(3 + 7/10) miles

We can rewrite: 0.25 = 1/4

replacing that:

D = (1/4)*(3 + 7/10) mi = (3/4 + 7/40) mi

   = (30/40 + 7/40)mi = (37/40)mi

Then the total distance that she walked over the weekend is:

d = (3 + 7/10) mi +  (37/40)mi

  = (120/40 + 28/40) mi + (37/40) mi

  = (185/40)mi = (160/40 + 25/40) mi = (4  + 5/8) mi

Perpendicular lines are lines that intersect at a 90-degree angle. So, for example, line ST is perpendicular to line CD. So line ST is perpendicular to line CD.

Perpendicular lines always intersect each other, however, all intersecting lines are not always perpendicular to each other. The two main properties of perpendicular lines are: Perpendicular lines always meet or intersect each other. The angle between any two perpendicular lines is always equal to 90.

Given that

line m and n are perpendiculars

then angle ∠a = ∠b

then

5x + 20 = 7x -4

7x -5x = 20 + 4

2x = 24

x = 24/ 2

x = 12.

The height of the water tower is 132 feet

We have the height to be 5 feet 4 inches

then 1 feet = 12 inches

inch = 1 / 12 ft

Then 4 inches = 1 / 12 x 4

= 1 / 3 ft

Height = 5 1/3

= 16 / 3

height of the shadow cast = 3 feet

For the water tank

74 ft 3 inches

= 74 x 3 / 12

297 / 4

the height of the tower

[tex]\frac{height of person}{height of shadow} =\frac{height of tower}{height of person}[/tex]

= [tex]\frac{16/3}{3} =\frac{x}{297/4} \\\\\frac{16}{3*3} =\frac{4x}{297}[/tex]
