Given:

The inequality is

[tex]2n+8>12[/tex]

To find:

The solution of the given inequality.

Solution:

We have,

[tex]2n+8>12[/tex]

Subtract 8 from both sides.

[tex]2n+8-8>12-8[/tex]

[tex]2n>4[/tex]

Divide both sides by 2.

[tex]\dfrac{2n}{2}>\dfrac{4}{2}[/tex]

It means, the value of n is greater than 2.

Therefore, the solution of given inequality is n > 2.

Write a linear function f with f(5)=7 and F(-2)=0.

Answers

Answer:

f(x)=x+2

Step-by-step explanation:

Slope= (7-0)/(5-(-2)) = 7/7 = 1

Y-intercept= 2

substitute the slope, 1, for m and the y-intercept, 2, for b to get:

f(x)=x+2

hope this helps!

The linear function f with f(5)=7 and F(-2)=0 is f(x) = x + 2

f(5) = 7

This means when x = 5 , y = 7

(5, 7)

f(-2) = 0

(-2, 0)

This implies when x = -2 , y = 0

Using the linear function formula,

y = mx + b

where

m = slope

b = y-intercept

Therefore, the function can be represented as follows:

m = 0 - 7 / -2 - 5 = -7 / -7 = 1

Therefore,

y = x + b

0 = -2 + b

b = 2

The function in relation to x can be represented as follows:

f(x) = x + 2

Point A is the incenter of triangle DEF. Point A is the incenter of triangle D E F. Lines are drawn from the points of the triangle to point A. Lines are drawn from point A to the sides of the triangle to form right angles and line segments A X, A Y, and A Z. Which must be true? Select three options

Answers

The points must be true for Point A which is the incenter of triangle DEF are 1> Point A is the center of the circle that passes through points X, Y, and Z. 2>Line segment A X is-congruent-to line segment A Y . 3> Point A is always inside triangle DEF .

What is incenter of triangle?

The incenter of a triangle is the point of intersection of all the three interior angle bisectors of the triangle. This point is equidistant from the sides of a triangle, as the central axis's junction point is the center point of the triangle's inscribed circle. The incenter of a triangle is also known as the center of a triangle's circle since the largest circle could fit inside a triangle. The circle that is inscribed in a triangle is called an incircle of a triangle.

According to the question

Point A is the incenter of triangle DEF .

Lines are drawn from point A to the sides of the triangle to form right angles and line segments A X, A Y, and A Z.  (X,Y,Z are points on middle of sides )

Now,

According to the properties of  incenter of the triangle  

1.> The circle that is inscribed in a triangle is called an incircle of a triangle.  

i.e

Point A is the center of the circle that passes through points X, Y, and Z.

2> The incenter of a triangle is equidistant from the sides of a triangle, as the central axis's junction point is the center point of the triangle's inscribed circle.  

i.e

Line segment A X is-congruent-to line segment A Y .

3> A triangle's incenter always lies inside the triangle.

i.e

Point A is always inside triangle DEF .

Hence, The points must be true for Point A which is the incenter of triangle DEF are 1> Point A is the center of the circle that passes through points X, Y, and Z. 2>Line segment A X is-congruent-to line segment A Y . 3> Point A is always inside triangle DEF .

The length of a room is 2 1/2 feet more than its width. If the perimeter of the room is 80 feet, find its width and length?​

Answers

Answer:

The width is 20.625 and the length is 19.375

Step-by-step explanation:

Let 2 1/2 + w = length

Let w = width

Equation:

2 1/2 + w + w = 80                     Combine liked terms

2 1/2 + 2w = 80                    

-2 1/2         -2 1/2                        Subtract 2 1/2 from both sides

2w  =   77.5

÷ 2     ÷ 2                                    Divide 2 from both sides

w = 41.25

Length:

2 1/2 + 41.25 = 165/4 or 38.75

Width:

41.25

41.25/2 = 20.625

38.75/2 = 19.375

The elevator of a building is currently 10 feet above ground level on the first floor. The building's elevator rises at a rate of 5 feet per second. You enter the elevator on the first floor. Let t, represent the number of seconds you are in the elevator and h(t) represent the height of the elevator (in feet). Write an equation for h(t) b. What will your height be in 12 seconds? c. What does h(5) = 35 represent?

Answers

Answer:

[tex]h(t) = 10 + 5t[/tex]

70 feet

Your height in 5 seconds is 35 feet

Step-by-step explanation:

From the question, we understand that:

[tex]Initial\ Height = 10[/tex]

[tex]Rate = 5[/tex] per second

Solving (a): Equation for h(t)

This implies that the height at t seconds and is calculated as thus:

[tex]h(t) = Initial\ Height + Rate * t[/tex]

Where t represents seconds

Substitute values for Initial Height and Rate

[tex]h(t) = 10 + 5* t[/tex]

[tex]h(t) = 10 + 5t[/tex]

Solving (b): Height in 12 seconds

This implies that:

[tex]t = 12[/tex]

Substitute 12 for t in [tex]h(t) = 10 + 5t[/tex]

[tex]h(12) = 10 + 5 * 12[/tex]

[tex]h(12) = 10 + 60[/tex]

[tex]h(12) = 70[/tex]

Hence, your height will be 70 feet

Solving (c): h(5) = 35 means?

Using the illustration in (b) above;

This means that your height in 5 seconds is 35 feet

Bill and John competed in the “Shot Put" event in their school's track
meet. Bill threw the shot 21 feet and 6 inches, while John threw the
shot 17 feet and 4 inches. How much greater was Bill's throw than
John's?

Answers

Answer:

4 feet and 2 inches

Step-by-step explanation:

First, find the difference between the number of feet in their throws:

21 - 17

= 4 feet

Since Bill's throw had 6 inches while John had 4 inches, subtract 2 inches from the 4 feet that we calculated earlier.

This gets us 4 feet and 2 inches, since there are 12 inches in a foot.

So, Bill's throw was 4 feet and 2 inches greater than John's.
