Answer:

4000

Step-by-step explanation:

5000 * .8 is 4000

Answer:

4000 students

Step-by-step explanation:

Number of computer science majors = 80% of 5000

                                                              = 0.8 * 5000

                                                              = 4000

Answer:

-6x + 3

Step-by-step explanation:

-3(2x - 1)

We use distributive property

so we mulitply the number that is outside of the paraenthesis (-3), to the numbers on the inside (2x - 1)

-3 × 2x = -6x

-3 × -1 = 3

So we have:

-6x + 3

And we cannot combine them so that is the answer.

Hope that helped!

Answer:

(4,7), (6,13), and (5,10)

Step-by-step explanation:

To determine if an ordered pair is a solution, substitute the coordinates in and check to see if they are true:

(2,2)

[tex]y=3x-5\\(2)\stackrel{?}{=}3(2)-5\\2\stackrel{?}{=}6-5\\2\neq1[/tex]

Thus, (2,2) is not a solution.

(4,7)

[tex]y=3x-5\\(7)\stackrel{?}{=}3(4)-5\\7\stackrel{?}{=}12-5\\7\stackrel{\checkmark}{=}7[/tex]

Thus, (4,7) is a solution.

(6,13)

[tex]y=3x-5\\(13)\stackrel{?}{=}3(6)-5\\13\stackrel{?}{=}18-5\\13\stackrel{\checkmark}{=}13[/tex]

Thus, (6,13) is also a solution.

Lastly, (5,10)

[tex]y=3x-5\\10\stackrel{?}{=}3(5)-5\\10\stackrel{?}{=}15-5\\10\stackrel{\checkmark}{=}10[/tex]

Thus, (5,10) is also a solution.

Answer:

a = c * SinФ

Step-by-step explanation:

SinФ = opp / hyp

c = hyp

a = opp

SinФ = a / c

therefore

a = c * SinФ

Answer:

F and H

Step-by-step explanation:

From the image attached, the location of the points are E = -9, F = -6, G = -2, H = 6, I = 8. The law of additive inverse states that for a number a, its additive inverse is a number that when added to a equals to zero. This number is usually opposite in sign to a and of the same magnitude i.e -a. The law is given as:

a + (-a) = 0

From the points, F is the additive inverse of H, hence:

F + H = 0

6 + (-6) = 6 - 6 = 0

Hence the two points are F ad H

Answer: 2(x-11)

Step-by-step explanation:

Disclaimer: The options are missing. They are as follows:

a. 2(11-x)

b. 11-2x

c. 2x-11

d. 2(x-11)

The algebraic expression that represents the word description: The product of two and the difference between a number and eleven is 2(x - 11). Hence, option d is the right choice.

An algebraic expression is a combination of variables and constants, as well as algebraic operations (addition, subtraction, etc.). Terms are the building blocks of expressions.

We are asked to find the algebraic expression that represents this word description The product of two and the difference between a number and eleven.

We let the unknown number be x.

We are said that the expression is the product of two and the difference between a number and eleven.

The difference between a number and eleven can be written as x - 11.

Now we need the product of this and two, that can be written as:

2(x - 11).

∴ The algebraic expression that represents the word description: The product of two and the difference between a number and eleven is 2(x - 11). Hence, option d is the right choice.

Answer:

9 tickets for $15

Step-by-step explanation:

9×1.80=16.20

Answer:

30

Step-by-step explanation:

A player answers x correct questions and y incorrect questions for a total of 40 questions.

x + y = 40

The score is obtained by subtracting y incorrect answers from two times the x of correct answers.  The player's score is 50.

2x - y = 50

Use substitution to solve.  Rearrange the first equation so that it is equal to y.  Then, substitute the y-value into the second equation.

x + y = 40

y = 40 - x

2x - y = 50

2x - (40 - x) = 50

2x - 40 + x = 50

3x - 40 = 50

3x = 90

x = 30

Since x was made to represent correct answers, the player had 30 correct answers.

Answer:

2⁸ > 2.38 × 10² > 6³ > 2.16 × 10¹ > [tex]\sqrt{300}[/tex], 300%

Step-by-step explanation:

Given numbers are,

2.38 × 10², √300, 2⁸, 300%, 6³, 2.16 × 10¹

We have to arrange these numbers in the decreasing order(from greatest to least)

2.38 × 10² = 2.38 × 100 = 238

√300 = 10√3 ≈ 17.32

2⁸ = 256

300% = [tex]\frac{300}{100}[/tex] = 3

6³ = 216

2.16 × 10¹ = 21.6

Therefore, decreasing order (from the greatest to least) will be,

256 > 238 > 216 > 21.6 > 17.32 > 3

2⁸ > 2.38 × 10² > 6³ > 2.16 × 10¹ > [tex]\sqrt{300}[/tex], 300%

Answer:

x = 4

Step-by-step explanation:

RT = RS + ST

RT = 36

RS + ST = 36

6x + 1  + x + 7 = 36

6x + x + 1 + 7 = 36  {Combine like terms}

7x + 8 = 36   {Subtract 8 from both sides}

7x + 8 - 8 = 36 - 8

7x = 28   {Divide both sides by 7}

7x/7 = 28/7

x = 4

Let us assume the number of calls be x

So

For Plan 1

Total monthly charges is $24 for unlimited calls

For Plan 2

There is a charge of $16 and $0.04 per call

We can write as

= 0.04x + $16

a)  Now the inequality equation is

0.04x + $16 > $24

0.04x > $8

x > 200

b)   Now if there are more than 200 calls than Plan 1 is more economical as compared with plan 2

UV=4 is the solution

The value of UV = 4.

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S.

There are different parts of an equation which include coefficients, variables, operators, constants, terms, expressions, and an equal to sign. When we write an equation, it is mandatory to have an "=" sign, and terms on both sides. Both sides should be equal to each other. An equation doesn't need to have multiple terms on either of the sides, having variables, and operators. An equation can be formed without these as well, for example, 5 + 10 = 15. This is an arithmetic equation with no variables.

Given:

UV = 4x, VW = 3x, and UW = 7

UW= UV + VW

7 = 4x + 3x

7 = 7x

x= 7/7

x=1

Hence, UV = 4

Answer:

Step-by-step explanation:

It usually works best for factoring to remove any common factors from the coefficients. Here, they are all even numbers, so have a common factor of 2. After taking that out, you have ...

  2(4x² -4x -3)

To factor this, you are looking for factors of (4)(-3) that have a sum of -4.

  -12 = 1(-12) = 2(-6) = 3(-4)

These pairs have sums of -11, -4, -1. So, we are interested in the factors 2 and -6. We can use those to rewrite the middle term, then factor by pairing.

  = 2(4x² +2x -6x -3) = 2((2x(2x+1) -3(2x+1)) = 2(2x -3)(2x +1)

Of these, the factors that are on your list of choices are ...

Answer:

zero

Step-by-step explanation:

the slope of a function m: y2-y1/x2-x1

m=-3-(-3)/5-(-5)

m=0/10=0

The slope of the line drawn passing through (- 5, - 3) and (5, - 3) is zero, so option C is correct.

An object having an endless length and no width, depth, or curvature is called a line. Since lines can exist in two, three, or higher-dimensional environments, they are one-dimensional things.

Given:

straight line drawn passing through (- 5, - 3) and (5, - 3)

Calculate the slope of the line as shown below,

[tex]m = y_2 - y_1 / x_2 - x_1[/tex]

m = slope

m = -3 - (-3) / 5 - (-5)

m = 0 / 10

m = 0

Therefore, the slope of the line drawn passing through (- 5, - 3) and (5, - 3) is zero.
