What is the area of the shaded region?​

Answer:

Step-by-step explanation:

 a : b

 9 : 6

 2 : x

Cross multiply

6*2 = 9x

12 = 9x

12/9 = x

4/3 = x

The number added to the numerator and the denominator is 2/3.

It is given in the question that when the same number is added to the numerator and denominator of fraction 5/7, the result is 17/23.

We have to find the number added to the numerator and the denominator.

Let the number be x.

Hence, according to the data given in the question, we get,

(5 + x)/(7 + x) = 17/23

By cross - multiplication, we get

23(5 + x) = 17 (7 + x)

Opening the bracket according to the distributive property of addition and multiplication, we get,

115 + 23x = 119 + 17x

23x - 17x = 119 - 115

6x = 4

x = 4/6

x = 2/3

Answer:

15. x = 4

17. AB = 9

Step-by-step explanation:

15.

Since B is in the middle of AC, AB + BC = AC

So,

x + 5 + 2x - 4 = 13

3x + 1 = 13

3x = 12

x = 4

17.

Since B is in the middle of AC, AB + BC = AC

So,

x + 16 + x + 17 = 19

2x + 33 = 19

2x = -14

x = -7

Going back to the question, it says to find the length of AB.

AB = x + 16 = -7 + 16 = 9

Answer: 2x+9>17 or  5x+10<10 compound inequalities is x<0

Step-by-step explanation:

What is Meant by Compound Inequality?

In Mathematics, a compound inequality is a sentence which has two statements connected using the word “and” or by the word “or”. If the statements are connected using the word “and”, then both the statements of the compound sentence are true at the same time. If the statements are connected using “or”, then the compound sentence is true if at least one statement is true.

2x+9>17 or  5x+10<10

Let take 2x+9>17

Subtract -9 on both sides

2x+9-9>17-9

2x+0>8

2x>8

Now we need to divide by 2 both sides

2x÷2>8÷2

x>4

Now we solve 5x+10<10

we need to subtract -10 on both side

5x+10-10<10-10

5x+0<0

5x<0

Now we need to divide  5 on both sides

5x÷5<0÷5

x<0

0<x>4

the value of x lies between 0 and 4.

A compound inequality is an inequality that combines two simple inequalities. A compound inequality is made up of two inequalities connected by the word “and” or the word “or.” To solve a compound inequality means to find all values of the variable that make the compound inequality a true statement.

lets take 2x+9>17

now lets subtract 9 from both sides.

2x + 9 > 17

     - 9 > -9

2x > 8

now divide both sides by 2

2x ÷ 2 > 8 ÷ 2

x > 4

lets take the second part i.e 5x +10 <10

substract 10 from both sides

5x + 10 < 10

     - 10 < -10

5x < 0

now divide both sides by 5

5x ÷ 5< 0 ÷ 5

x < 0

0<x>4

the value of x lies between 0 and 4.

The area of a triangle is 4 square units.

Given that, the coordinates of the triangle ABC are A(4, 3), B(5, 1) and C(1, 1).

We need to find the area of a triangle ABC.

The area of a triangle is defined as the total space occupied by the three sides of a triangle in a 2-dimensional plane. The basic formula for the area of a triangle is equal to half the product of its base and height, i.e., A = 1/2 × b × h.

The base of the triangle = |5-1|=4

From vertices, A(4, 3) to the base the distance is 2 units at the vertice (4, 1)

So, the height of the triangle = 2 units

The equation that could be used to determine, m, the average number of miles she would have to ride to meet her goal is; m = (55.5 - 19)/5

Distance that she wants to ride this week = 55.5 miles

Distance she has already ridden so far = 19 miles

Now, we are told that she will ride 5 more days.

If m is the average number of miles she has to ride to meet her goal, then we can say that;

5m + 19 = 55.5

Making m the subject by, we have;

m = (55.5 - 19)/5

As a reminder, an arithmetic sequence or arithmetic progression (AP) is a progression in which the difference (called the tolerance) between two consecutive terms in the progression is constant.

Therefore, the expression for the nth term is

an = a₁ + (n − 1) d

and in general

an = am + (n - m) d.

where d is the difference.

For an arithmetic series with initial term a₁ and difference between terms of d

an = a₁ + (n − 1) d

We are told

d = -2 and

S8 = 240

So,

a1 = 240 = a1 + ( 30 - 1) * ( -2 ) = a1 - 58

a1 = 240+58 =298

======================================================

Explanation:

To find the inverse, we swap x and y, then solve for y.

y = 2x-3

x = 2y-3

x+3 = 2y

2y = x+3

y = (x+3)/2

y = x/2 + 3/2

y = (1/2)x + 3/2

This shows the original function y = 2x-3 leads to the inverse y = (1/2)x+3/2, and vice versa.

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

Another approach:

Since we're given a list of multiple choice answers, we can rule out the non-answers.

Plug x = 0 into the first equation of choice A. It leads to y = 2

That output 2 is then plugged into the second equation for choice A. It leads to y = 13/2. We do not get the original input 0, which shows that the equations in choice A do not undo one another. They aren't inverses of each other.

This allows us to rule out choice A. Choices B and C are similar stories.

Notice that plugging x = 0 into the first equation of choice D leads to the output y = -3. Then plug this as the input into y = (1/2)x+3/2 and you should get y = 0 to get us back where we started. This partially helps confirm we have a pair of functions that are inverses of each other. I'll let you try other values.

B. Amount of space the dog will occupy is: 2.55 ft³. Josiah should buy the medium crate.

2. 21.05 ft²

The volume of a rectangular prism = (length)(width)(height).

1. Part A:

Length of the rectangular prism crate = 2.5 ft

Width = 1.7 ft

Height = 2 ft

Volume of the rectangular prism crate = (2.5)(1.7)(2)

Volume of the rectangular prism crate = 8.5 ft³

2/3 of the volume of the rectangular prism crate = 2/3(8.5) = 5.7 ft³

Part B:

Amount of space the dog will occupy = volume = (length)(width)(height).

Length = 2 ft

Height = 1 2/3 = 1.7 ft

Width = 3/4 = 0.75 ft

Amount of space the dog will occupy = volume = (2)(0.75)(1.7)

Amount of space the dog will occupy = volume = 2.55 ft³

The space the dog will occupy is less than 2/3 of the space of the crate, therefore, Josiah should buy the medium crate.

2. Amount of fabric needed to cover the crate = surface area of rectangular prism - (lw) = 2·(1.7·2.5+2·2.5+2·1.7) - (2.5)(1.7)

No, The given relation isn't a function.

[ For a relation to be a function, every value that lies in the domain ( set A ) should have only one corresponding value in its Range ( set B ) but here, -1 has two corresponding values that are : (-1) and (2) ]

Therefore, conclusion can be made that the given relation isn't a function.

Answer:

Not a function.

Step-by-step explanation:

Functions

A function is a special type of relation where each input (x-value) has a single output (y-value).

The given function is not a function as the input value of x = -1 has multiple output values of y = 2 and y = -1.

From the question, the first table is not a function while the other two tables are functions.

A function is a correspondence or mapping from a first set of numbers, called the domain of the function, to a second set of numbers, called the range of the function, such that for each member of the domain there is exactly one member of the range.

A function is said to be one-to-one if every y value has exactly one x value mapped onto it, and many-to-one if there are y values that have more than one x value mapped onto them. This graph shows a many-to-one function.

4) We see that all the y-values are the same or equal. Thus, we can say that it is not a function because it doesn't match the definition above.

5) Yes the table describes a function because all input values produces a unique output y-value.

6) Yes, the table represents a function because all input values produces a unique output y-value.
