Answer:

The correct answer would be B, Sometimes.

Step-by-step explanation:

Rational numbers are sometimes the natural numbers.

Rational numbers are the numbers that can be expressed as a quotient or fraction of two integers. Rational numbers can be in the form of decimals or natural numbers. Natural Numbers are the normal integers like 1, 2, 3, 4, etc. So the resulting numbers of any equation will give a rational number or a natural number. So it is so correct to say that rational numbers are sometimes the natural numbers.  

8n + 12 +(-9) -(-6n)

12 + -9 = 12-9 = 3

8n - (-6n) = 8n + 6n = 14n

The equation becomes 14n + 3

Answer:

The other 2 sides have lengths 24 and 25.

Step-by-step explanation:

h^2 = x^2 + 7^2 where x is the other leg and h is the hypotenuse.

h^2 - x^2 = 49

(h + x) (h - x) = 49

The factors of 49 are 1 , 7 , and 49.

h + x could be 49 and h - x could be 1:

(25 + 24)(25 - 24) = 49.

So h = 25 and x = 24.

Answer:

Part 1) The measure of x is 23°

Part 2) The value of y is [tex]y=5\ units[/tex]

Part 3) The value of z is [tex]z=12\ units[/tex]

Step-by-step explanation:

step 1

Find the value of x

we know that

[tex]x+67\°=90\°[/tex] ------> by complementary angles

[tex]x=90\°-67\°=23\°[/tex]

step 2

Find the value of y

In the right triangle of the figure

[tex]cos(67\°)=\frac{y}{13}[/tex] -----> adjacent side angle of 67 degrees divided by the hypotenuse

[tex]y=(13)cos(67\°)=5\ units[/tex]

step 3

Find the value of z

In the right triangle of the figure

[tex]sin(67\°)=\frac{z}{13}[/tex] -----> opposite side angle of 67 degrees divided by the hypotenuse

[tex]z=(13)sin(67\°)=12\ units[/tex]

Answer:

36 minutes

Step-by-step explanation:

In order to find how many minutes it takes to fill 675 bottles, we need to find how many bottles the machine produces in one minute.

To do so, we can divide 150 by 8, which would give us the total amount of bottles produced in one minute.

150/8 = 18.75

So, 18.75 bottles are produced in one minute

To find the total number of minutes it takes to fill 675 bottles, we can divide 675 by the number of bottles produced in one minute, which is 18.75

675/18.75 = 36

Therefore, it takes the machine 36 minutes to fill 675 bottles.

Given : Machine fills 150 bottles of water every 8 minutes

[tex]\mathsf{\implies Machine\;fills\;1\;bottle\;of\;water\;in\;\left(\dfrac{8}{150}\right)\;minutes}[/tex]

[tex]\mathsf{\implies Machine\;fills\;(675 \times 1)\;bottles\;of\;water\;in\;\left(675 \times \dfrac{8}{150}\right)\;minutes}[/tex]

[tex]\mathsf{\implies Machine\;fills\;675\;bottles\;of\;water\;in\;\left(675 \times \dfrac{4}{75}\right)\;minutes}[/tex]

[tex]\mathsf{\implies Machine\;fills\;675\;bottles\;of\;water\;in\;\left(135 \times \dfrac{4}{15}\right)\;minutes}[/tex]

[tex]\mathsf{\implies Machine\;fills\;675\;bottles\;of\;water\;in\;\left(9 \times 4}\right)\;minutes}[/tex]

[tex]\mathsf{\implies Machine\;fills\;675\;bottles\;of\;water\;in\;\boxed{\mathsf{36}}\;minutes}[/tex]

Answer:

A'(-2, -3)  B'(0, -3)  C'(-1, 1)

Step-by-step explanation:

change the signs for the Y coordinates because you are reflecting over the X-Axis. so 3 becomes -3, and -1 becomes 1. leave the X coordinates unchanged.

The reflection triangle ABC over the x axis is A'(–2, -3), B'(0, -3), and C'(–1, 1).

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

If a point A(x, y) is reflected over the x axis, the new point is at A'(x, -y).

The reflection of A(–2, 3), B(0, 3), and C(–1, –1) over the x axis is A'(–2, -3), B'(0, -3), and C'(–1, 1).

Answer:

The correct answer is D.

The correct identity Samuel should use is: D. (20 x 6) + (4 x 6) = 24 x 6

To find the total cost of ordering 24 lunch specials at $6.00 each, Samuel needs to compute 24×6.

The distributive property states that:

a×(b+c) = (a×b)+(a×c)

In this problem, we can break down 24 into 20 and 4, and then apply the distributive property.

This gives us:

24×6 = (20+4)×6

= (20×6) + (4×6)

The required inequality would be 99x + 84 ≤ 1,150. so the correct option is C.

If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true. Such values are called solution to that equation or inequality. Set of such values is called solution set to the considered equation or inequality.

Given;

The cost of the shirt she bought = $ 84,

And the cost of each watch she bought = $ 99,

Now Suppose she bought x watches,

So, the cost of x watches = 99x dollars,

Also, her total spending = 84 + 99x

Since she has a total budget of $1,150,

That is her spending can not be exceed $ 1,150, ( or spending must be less than or equal to $ 1150 )

⇒ 99x + 84 ≤ 1,150

Hence the required inequality would be 99x + 84 ≤ 1,150. so the correct option is C.

Answer:

The first one: y - 2 = -5(x - 2)

Step-by-step explanation:

Answer:

the function y – 2 = –5(x – 2) is linear.

Step-by-step explanation:

We need to find the correct option from provided options which represents a linear function

Since, the linear equation is in the form of y=mx+c where m is slope of line.

In first part y – 2 = –5(x – 2)

Simplify, the function

[tex]y -2 = -5x + 10[/tex]

Add both the sides by 2, in above equation

[tex]y = -5x +12[/tex]

This function is in the form of y=mx+c

so, this is a linear function

In second part x + 7 = –4(x + 8)

Simplify, the function

[tex]x+7= -4x+32[/tex]

subtract both the sides by 7, in above expression

[tex]x= -4x+32-7[/tex]

[tex]x= -4x+25[/tex]

add both the sides by 4x,

[tex]x +4x= 25[/tex]

[tex]5x= 25[/tex]

divide both the sides by 5,

[tex]x =5[/tex]

This is not in the form of y=mx+c

so, this is not a linear function

In third part y – 3 = y(x + 4)

Simplify, the function

[tex]y-3= yx+4y[/tex]

add both the sides by 3,

[tex]y= yx+4y+3[/tex]

This is not in the form of y=mx+c

so, this is not a linear function

In fourth part y + 9 = x(x - 1)

Simplify, the function

[tex]y+9= x^{2}-x[/tex]

subtract both the sides by 9,

[tex]y= x^{2}-x-9[/tex]

This is not in the form of y=mx+c

so, this is not a linear function

Therefore, the function y – 2 = –5(x – 2) is linear.

Answer:

D. x = 8

Step-by-step explanation:

MNOP is a trapezoid with a meadian QR

So

QR = 1/2(NO + MP)

2(QR) = NO + MP

2(16) = 8 + 2x + 8

32 = 2x + 16

2x = 16

 x = 8

Answer:

The correct answer option is D. x = 8.

Step-by-step explanation:

We are given a trapezoid MNOP with the median QR and we are to find the value of x.

If we observe the figure, we can see that the length QR is the double of NO which means 8 units are added to NO. So the ratio for NO and MP would be 1:3.

NO = 8

QR = 8 + 8 = 16

MP = 8 + 8 + 8 = 24

Finding x:

2x + 8 = 24

2x = 24 - 8

2x = 16

x = 8

Answer:

3.86 (or 3.9)

Step-by-step explanation:

There's a logarithm function on a graphing calculator

The function that is graphed below is y = |x - 8| + 2.

Option A is the correct answer.

A function has an input and an output.

A function can be one-to-one or onto-one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

The graph of the function y = |x - 8| + 2 is a V-shaped graph with the vertex at the point (8, 2).

The function is defined as the absolute value of the difference between x and 8, plus 2.

When x is less than 8, the expression inside the absolute value bars, (x - 8), is negative, so the function becomes y = -(x - 8) + 2.

Simplifying this expression, we get y = -x + 10, which is the equation of a line with a slope of -1 and a y-intercept of 10.

This line goes downwards to the left of the vertex (8, 2).

When x is greater than 8, the expression inside the absolute value bars, (x - 8), is positive, so the function becomes y = (x - 8) + 2.

Simplifying this expression, we get y = x - 6, which is the equation of a line with a slope of 1 and a y-intercept of -6.

This line goes upwards to the right of the vertex (8, 2).

At the vertex (8, 2), the function takes the minimum value of 2.

Overall, the graph of the function y = |x - 8| + 2 is a V-shaped graph with the vertex at (8, 2), and two lines with slopes of -1 and 1 on either side of the vertex. The graph is symmetrical about the vertical line x = 8.

Thus,

The function that is graphed below is y = |x - 8| + 2.
