Given x=-3, y=6, and z=-4 22-3y+4x=​

Answers

Answer 1

Answer: -8

Explanation: It's a good idea to get into the habit of using parenthses

when substituting numbers in for variables.

Since x = -3 and y = 6, 22 - 3y + 4x is 22 - 3(6) + 4(-3).

3(6) is 18 so we have 22 - 18 + 4(-3).

4(-3) is - 12 so we have 22 - 18 + -12.

Now, 22 - 18 is 4 and 4 + -12 is -8.

Answer 2

Answer:

-8

Step-by-step explanation:

Subsitute the variable "y" with 6 and the variable "x" with -3. Once the variables are replaced with the right numbers, the equation should read 22- 3(6) +4(-3). Using PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction) you should do what's in the parentheses first. -3 times 6 is -18 and 4 times -3 is -12. 22-18-12= -8

What are the real numbers?

Real numbers include rational numbers like positive and negative integers, fractions, and irrational numbers.

The set of real numbers, which is denoted by R, is the union of the set of rational numbers (Q) and the set of irrational numbers.

Rational Numbers; Any number specified in the form of a p/q or ratio fraction is called a rational number. The numerator is defined as p, and the denominator is represented as q, where q is not equal to zero. A rational number may be an integer, whole, and natural number.

For example: 0.67, 17, 214, etc.

Irrational Number; Irrational numbers are defined as the real number that cannot be represented as a simple fraction. In other words, it cannot be represented as a ratio, such as p/q, where p and q are integers, q≠0. It is the opposite of rational numbers.

For example; √5, √11, √21, etc.

Natural Numbers; An integer greater than 0 is a natural number. Natural numbers start at 1 and move to infinity.

For example; 1, 2, 3, 4, 5.

Whole Numbers; The whole number is the number system that contains all positive integers from 0 to infinity. The whole number is an integer of 0 or greater numbers.

For example: 1, 2, 3, 4, 5…..

E(119.5)= (the answer) meters

Answers

Answer:

[tex]E(119.5)= 730m[/tex]

Step-by-step explanation:

Given

[tex]E(t)= 1200(120-t)+520(120-t)^2[/tex]

Required

Determine E(119.5)

[tex]E(t)= 1200(120-t)+520(120-t)^2[/tex]

Simply substitute 119.5 for t

[tex]E(119.5)= 1200(120-119.5)+520(120-119.5)^2[/tex]

Evaluate the expressions in bracket

[tex]E(119.5)= 1200(0.5)+520(0.5)^2[/tex]

Solve 0.5²

[tex]E(119.5)= 1200 * 0.5+520*0.25[/tex]

[tex]E(119.5)= 600+130[/tex]

[tex]E(119.5)= 730[/tex]

how do i solve number 8 and 9?

Answers

Answers & Step-by-step explanation:

A square root is a number that when multiplied by itself, equals the number you were asked to square root. For example, 2 is the square root of 4, because 2 x 2 = 4.

There is a method in algebra to simplify square roots into smaller square roots, where one can be solved. To do this, we need to find a perfect square that can be multiplied with the other square root to equal the number you were asked to square root.

Now, let's solve your problems!

___________________________________________________________

5.

[tex]\sqrt{56}[/tex] = [tex]\sqrt{2^{2} * 14[/tex]

Now, we pull out the [tex]2^{2}[/tex] from under the radical, since we can square root this. [tex]\sqrt{2^{2} }[/tex] is simply 2.

[tex]2\sqrt{14}[/tex]

Since we can't solve [tex]\sqrt{14}[/tex], this is the final answer that your assignment is wanting.

___________________________________________________________

6.

[tex]\sqrt{84}[/tex] = [tex]\sqrt{2^{2} * 21[/tex]

Now, we pull out the [tex]2^{2}[/tex] from under the radical, since we can square root this. [tex]\sqrt{2^{2} }[/tex] is simply 2.

[tex]2\sqrt{21}[/tex]

Since we can't solve [tex]\sqrt{21}[/tex], this is the final answer.

___________________________________________________________

7.

[tex]\sqrt{-9}[/tex] = [tex]\sqrt{-1 * 9}[/tex]

Now, since this the number is negative, we must separate the negative out. so [tex]\sqrt{-9}[/tex] becomes [tex]\sqrt{-1 * 9}[/tex]. Since the square root of 9 is 3, we can rewrite this as:

[tex]3\sqrt{-1}[/tex]

However, since [tex]\sqrt{-1}[/tex] is imaginary, we must replace it with i. This also allows us to get rid of the square roots.

The answer becomes:

3i

___________________________________________________________

8.

[tex]3\sqrt{18}[/tex]

This one is already partly simplified. Notice how the 3 is not under the radical. The only thing we have to work with is the [tex]\sqrt{18}[/tex].

[tex]\sqrt{18}[/tex] = [tex]\sqrt{9 * 2}[/tex]

We can square root 9 to get 3.

[tex]3\sqrt{2}[/tex]

Now, we multiply back the 3 from earlier to get:

[tex]9\sqrt{2}[/tex]

___________________________________________________________

9.

[tex]\sqrt{28a^{2}b^{3} }[/tex]

This one may look daunting because we have the variables, but we can break it down and solve it just as easily as the rest. The first step is to square root the a² term, the answer is a. We can rewrite this as:

[tex]a\sqrt{28b^{3} }[/tex]

Next, we need to simplify [tex]\sqrt{28}[/tex], just like we did with all the other problems.

[tex]\sqrt{28}[/tex] = [tex]\sqrt{4 * 7}[/tex]

Since [tex]\sqrt{4}[/tex] is 2, we can move it out of the radical.

[tex]\sqrt{28} = 2\sqrt{7}[/tex]

Since we can do anything with the [tex]b^{3}[/tex] term, that stays under the radical.

The answer is:

[tex]2a\sqrt{7b^{3} }[/tex]

Bentley have to pay in a month in which he downloaded 10 songs? How much would
he have to pay if he downloaded s songs?

Answers

Answer: Bentley have to pay  $20.5 in a month in which he downloaded 10 songs.

Bentley have to pay  $(13+0.75s) in a month in which he downloaded s songs.

Step-by-step explanation:

As per given,

Total amount need to pay = (Monthly cost) + (Number of songs downloads)  x (Charges for each song)

Here, Monthly cost = $13

Charges for each song = $0.75

If Number of songs downloads = 10

Then, Total amount need to pay = $ (13 +(10) (0.75))

= $( 13+7.5)

= $ 20.5

So, Bentley have to pay  $20.5 in a month in which he downloaded 10 songs.

If Number of songs downloads = s

Then, Total amount need to pay (in $) = 13 + (s)(0.75)

= 13+0.75s

So, Bentley have to pay  $(13+0.75s) in a month in which he downloaded s songs.

If Number of songs downloads = 10

$ 20.5

If Number of songs downloads = s

13+0.75s

7) If AB = 3x - 8 and BC = x + 12, find the value of x.​

Answers

Answer:

Step-by-step explanation:

The question is incomplete. Here is the complete question.

In a square ABCD, if AB = (3x-8) and BC = (x+12), find the value of x. Also, find the length of each side of the square.

Note that all sides of a square are equal. Hence AB = BC for the square ABCD.

Given AB = (3x-8) and BC = (x+12), then AB = BC

3x-8 = x+12

collect like terms;

3x-x = 12+8

2x = 20

x = 20/2

x = 10

Substitute x = 10 into any of the side. Using side AB

AB = 3x-8

AB = 3(10)-8

AB = 30-8

AB = 22

BC = x+12

BC = 10+12

BC = 22

Hence x = 10 and the length of each side is 22

Answers

Answer:

AC =5

BC =  12

AB = 13

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2

(n-1)^2 + (2n)^2 = (n+7)^2

FOILing

n^2-2n+1  + 4n^2 = n^2+14n+49

Combine like terms

5n^2-2n+1   = n^2+14n+49

Bring everything to the left

5n^2-2n+1 -n^2-14n-49  = n^2+14n+49-n^2-14n-49

4n^2 -16n -48 = 0

Divide by 4

n^2 -4n -12 = 0

Factor

( n-6)(n+2) =0

Using the zero product property

n-6 =0  n+2 =0

n=6    n=-2

Since the length cannot be negative

n=6

AC = n-1 = 6-1 =5

BC = 2n = 2*6 = 12

AB = n+7 = 6+7 = 13

Given :

Hypotenuse of right angle triangle = n + 7

Base = n - 1

Altitude = 2n

Using Pythagoras theorem :

→ ( n + 7 )² = (n - 1)² + (2n)²

→ n² + 14n + 49 = n² - 2n + 1 + 4n²

→ n² + 14n + 49 = 5n² - 2n + 1 = 0

→ n² + 14n + 49 - 5n² + 2n - 1 = 0

→ -4n² + 16n + 48 = 0

→ -4(n² - 4n - 12) = 0

→ n² - 6n + 2n - 12 = 0

→ n(n - 6) + 2(n - 6) = 0

→ (n - 6)(n + 2) = 0

As n ≠ Negative

So, n ≠ -2

So, n = 6

Hypotenuse = n + 7 = 6 + 7 = 13

Base = n - 1 = 6 - 1 = 5

Altitude = 2n = 2 × 6 = 12

So,

AB = 13

AC = 5

BC = 12
