D: 24d = 212

Answer:

1.6448 * 10^4.

Step-by-step explanation:

16448

There are 4 digits after the first so the exponent is 4.

1.6448 * 10^4.

Answer:  multiplied together or divided, the answer is positive. If two negative numbers are multiplied together or divided, the answer is positive.

Step-by-step explanation:

The result of adding a negative number and a positive number will depend on the magnitude of the two numbers and which one is larger.

Subtraction is a mathematical operation that deducts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

In mathematics, adding a negative number and a positive number involves combining two quantities with opposite signs. When we add a negative number and a positive number, we can think of it as "subtracting the absolute value of the negative number from the positive number."

For example, if we have -3 + 5, we can rewrite it as 5 - 3, which equals 2. In this case, we are subtracting the absolute value of the negative number (3) from the positive number (5).

Similarly, if we have -7 + 2, we can rewrite it as 2 - 7, which equals -5. In this case, we are subtracting the absolute value of the negative number (7) from the positive number (2), but since the negative number has a larger absolute value, the result is negative.

So, the result of adding a negative number and a positive number will depend on the magnitude of the two numbers and which one is larger.

The complete question is as follows:

What is a negative plus a positive?

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

Explanation:

The blue parent function has a positive coefficient of 1. The purple g(x) function is a reflection of f(x) over the x axis, so everything is now negative. The coefficient must be negative as well.

But the answer is simply not g(x) = -x^2 because plugging x = 3 does not lead to y = -6 as the point (3,-6) shows.

Let's say the coefficient is k for now. So we have y = kx^2

Plug in x = 3 and y = -6. Solve for k

y = kx^2

-6 = k(3)^2

-6 = k*9

9k = -6

k = -6/9

k = -2/3

So we update y = kx^2 into y = (-2/3)x^2

Meaning that g(x) = (-2/3)x^2 is the equation of the purple curve.

Plug x = 3 into g(x) to find that

g(x) = (-2/3)x^2

g(3) = (-2/3)(3)^2

g(3) = (-2/3)(9)

g(3) = -6

which is the output we want, so this confirms we have the correct coefficient.

Answer:

y=(-2/3)x^2

The natural numbers from 1 to 30:

1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30.

The prime numbers are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29.

Prime Numbers can only divide by themselves and 1.

Prime Numbers From 1 to 30: 2,3,5,7,11,13,17,19,23,29.... ( 10 )

Step-by-step explanation:

so, x+4/x-1=11/16

16x+64=11x-11

16x-11x=-11-64

5x=-75

x = -15

also, x+1 = -14

x =first number

x+1 = second number

(x) + 4 = x + 4 = 1 ^ new number [first number + 4]

(x + 1) -2 = x - 1 = 2 ^ new number [second number - 2]

[tex]\frac{x+4}{x-1}=\frac{11}{16}[/tex]

now, we resolve it:

[tex]\frac{16(x+4)-11(x-1)}{16(x-1)}=0[/tex]

[tex]\frac{16x+64-11x+11}{16x-16}=0[/tex]

[tex]\frac{5x+75}{16x-16}=0[/tex]

we eliminate the denominator and do c.e.: 16x - 16 ≠ 0; 16x ≠ 16; x ≠ 1

5x + 75 = 0

x = - 15

so x + 1 = - 14

Answer:

Possible perimeters:

50 inches, 28 inches, 22 inches, 20 inches.

Step-by-step explanation:

Given that:

Area of triangle = 24 square inches

Side lengths of rectangle are integers.

To find:

Possible perimeter of this rectangle = ?

Solution:

Here, options are missing, so let us calculate all possibilities for the perimeter.

The formula for Area of a rectangle is given as:

[tex]A = Length \times Width[/tex]

Let us make integer factors of 24 first of all.

[tex]24 = 1 \times 24\\24 = 2 \times 12\\24 = 3 \times 8\\24 = 4 \times 6[/tex]

These are the four possibilities of length and breadth.

Let us calculate the possible perimeter for each case using the formula for perimeter:

[tex]Perimeter = 2\times (Length + Width)[/tex]

1st possible option:

[tex]Perimeter = 2\times (1+ 24) = 50\ inches[/tex]

2nd possible option:

[tex]Perimeter = 2\times (2+ 12) = 28\ inches[/tex]

3rd possible option:

[tex]Perimeter = 2\times (3+ 8) = 22\ inches[/tex]

4th possible option:

[tex]Perimeter = 2\times (4+ 6) = 20\ inches[/tex]

Answer:

3 : 1

Step-by-step explanation:

[tex] \huge7.5 : 2.5 = \frac{7.5}{2.5} = \frac{3}{1} = 3 : 1 [/tex]

The equivalent ratio to 7.5 : 2.5 is given by dividing both elements by 2.5, the ratio is: 3 : 1

Remember that in a ratio A : B we can always multiply or divide both numbers by the same number, and the ratio does not change.

So, for the ratio:

7.5 : 2.5

To be in the form of:

n : 1

We can just divide both elements by 2.5, so we get:

7.5/2.5 = 3

2.5/2.5 = 1

Then we conclude that:

7.5 : 2.5 is equivalent to 3 : 1

Step-by-step explanation:

refer to the picture given

Answer: Choice A) z = -3

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

Work Shown:

-2z + 3 + 7z= -12

5z+3 = -12

5z = -12-3 .... subtract 3 from both sides

5z = -15

z = -15/5 .... divide both sides by 5

z = -3

Answer:

A. z = -3

Step-by-step explanation:

Answer:

x = 3/10

Step-by-step explanation:

2 1/3 = 2 + 1/3 = 6/3 + 1/3 = 7/3

1 1/2 = 1 + 1/2 = 2/2 + 172 = 3/2

2(1 1/2 - x) =  7/3 + 1/15

2(3/2 - x) = 35/15 + 1/15

2*3/2 + 2*-x = 36/15

3 - 2x = 36/15

-2x = 36/15  - 3

-2x = 36/15  -  45/15

-2x = -9/15

x = (-9/15)/-2

x = -9 / (15*-2)

x = 9/30

x = 3/10

verify:

2(3/2 - 3/10) = 36/15

2*3/2 + 2*-3/10 = 36/15

3 - 6/10 = 36/15

30/10 - 6/10 = 36/15

24/10 = 36/15 = 72/30

Answer: D = {-5 ≤ x ≤ -2  or  1 ≤ x < 5}

Step-by-step explanation:

When we have a function f(x) = y, the domain is defined as all the possible values of x that the function maps into other values.

In our graph, we can see two curves.

The first one (the one at the left)

Has two black dots, one at x = -5, and other at x = -2

(black dots means that the value is included, white dots means that the value is not included)

So this first part of the domain is:

-5 ≤ x ≤ -2.

Now, the second part has a black dot in x = 1, and a white dot in x = 5, so we can write this part of the domain like:

1 ≤ x < 5

Then the domain of our function is:

D = {-5 ≤ x ≤ -2  or  1 ≤ x < 5}

Answer:

66

Step-by-step explanation:

The height of the person in inches by unit conversion will be 66 inches.

To convert any unit into another is called a unit conversion.

In order to convert units, we need to care about their dimensions their dimension should not be changed.

It is known that,

1 feet = 12 inches

Multiply both sides by 5.5

5.5 feet = 12 x 5.5 = 66 inches

Hence "The height of the person in inches by unit conversion will be 66 inches".

Step-by-step explanation:

25 + 15 = 40

Answer:

40b

Step-by-step explanation:

We are given the expression:

25b+15b

and asked to simplify.

To simplify, we must combine like terms. Let's analyze the terms.

25b ⇒ has a variable "b"

15b ⇒ also has a variable "b"

The like terms in this expression are the terms with a variable, b.

To combine like terms, add the coefficients and leave a b on the end.

(25+15)*b

(40)*b

40b

The expression 25b+15b simplified is 40b.

Answer:

Money with Peter = $ 40

Step-by-step explanation:

Let 'x' be the money left with Peter

Money left with Peter after fixing his car = 1000 - 500 = 500

500 is divided into 5 equal parts and 4 parts he gave away. 500 - 400 = 100

x = (1000 - 500) - 400 - 60

= 500 - 400 - 60

= 100 - 60

x =$  40
