Answer:  Natasha = 480; Richard = 240, Stephen = 80

Step-by-step explanation:

Let N, R, and S stand for the amounts Natasha, Richard and Stephen receive.  The problem tells us that:

N = 2R, and

R = 3S

We know that N+R+S = 800

Since N=2R and R=3S, N = 6S

N+R+S = 800

6S+3S+S=800

10S=800

S=80

R=3S or 240

N=2R or 480

Conclusion:

N gets 480

R gets 240,

and S gets 80

That adds to 800.

. . .  AND the last conclusion is that I need to meet Natasha.  Please send Stephen home.

Answer:

A point is plotted on a horizontal number line.The absolute value of the number represented by the point is 6.If the point is to the left of 0, then the point is located at -6.If the point is to the right of 0, then the point is located at 6.Whether the point is to the left or right of 0, the distance from 0 to the point is 6 units.

Answer:

See explanation!

Step-by-step explanation:

The contrapositive of a conditional is similar to, yet different from, the inverse of the conditional.

The best way to explain this is to create an example. You should start by creating a conditional; you can then form the conditional's inverse and contrapositive.

Here is an example:

Conditional: If C, then D. (starting statement)

Inverse: If not C, then not D. (opposite of the conditional)

Contrapositive: If not D, then not C. (reversed opposite of the conditional)

Based on the information from the example, you can conclude:

Primary Similarity:

Both the contrapositive and the inverse are opposites of the conditional (both contain not, implying something would not happen under the given circumstances, rather than something would happen under those circumstances).

Primary Difference:

The contrapositive is a reversed version of the inverse; this causes them to most commonly have different meanings.

I am sure you could find more similarities/differences, but these were the two that stood out to me the most!

I hope this helps! :)

Answer: 1953

Step-by-step explanation: You need to subtract 7768 and 7117 to find the average change in 2 years; you get 651, divide this by 2 to find the amount of change in 1 year and you'll get 325.5, now if we take 325.5 times 6 (the amount of years until 2016) you will find 1953 as the answer.

Answer:

( 8 , 6 )

Step-by-step explanation:

A = ( 2 , 2 ) and C = ( 5 , 4 )

→ Form an equation

[tex]\frac{2+x}{2} =5[/tex]   and   [tex]\frac{2+y}{2}=4[/tex]

→ Now solve them

2 + x = 10 and 2 + y = 6

→ Simply find the values

x = 8 and y = 6

SOLUTION :

[tex] \large{ \rightarrow{ \tt{ \: (5 \: ,4 \: ) = ( \frac{2 + x}{2} \: , \frac{2 + y}{2} )}}}[/tex]

[tex] \large{ \tt{5 = \frac{2 + x}{2} }}[/tex]

[tex] \large{ \rightarrow{ \tt{10 = 2 + x}}}[/tex]

[tex] \large{ \rightarrow{\tt{10 - 2 = x}}}[/tex]

[tex] \boxed{ \large{ \rightarrow \tt{x = 8}}}[/tex]

[tex] \large{ { \tt{4 = \frac{2 + y}{2} }}}[/tex]

[tex] \large{ \rightarrow{ \tt{8 = 2 + y}}}[/tex]

[tex] \large{ \rightarrow{ \tt{8 - 2 = y}}}[/tex]

[tex] \boxed{ \large{ \rightarrow{ \tt{y = 6}}}}[/tex]

[tex] \large{ \boxed{ \tt{OUR \: FINAL \: ANSWER : \: D. \: (8 \:, 6 \: ) }}}[/tex]

Hello!

The slope of a line is found using the following formula:

[tex]m=\frac{9-5}{-2-2}[/tex]

[tex]m=\frac{4}{-4}\\m=-1[/tex]

So the slope is -1.

The distance between two points is the number of units between them

The possible value of x is -66

The given parameters are:

[tex]\mathbf{S = (-6,8)}[/tex]

[tex]\mathbf{T = (x,-3)}[/tex]

[tex]\mathbf{ST = 61}[/tex]

Distance ST is calculated using:

[tex]\mathbf{d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}}[/tex]

So, we have:

[tex]\mathbf{d = \sqrt{(-6 - x)^2 + (8 - -3)^2}}[/tex]

[tex]\mathbf{d = \sqrt{(-6 - x)^2 + (8 +3)^2}}[/tex]

[tex]\mathbf{d = \sqrt{(-6 - x)^2 + 11^2}}[/tex]

Substitute 61 for d

[tex]\mathbf{ \sqrt{(-6 - x)^2 + 11^2} = 61}[/tex]

Square both sides

[tex]\mathbf{ (-6 - x)^2 + 11^2 = 61^2}[/tex]

[tex]\mathbf{ (-6 - x)^2 + 121 = 3721}[/tex]

Subtract 121 from both sides

[tex]\mathbf{ (-6 - x)^2 = 3721 - 121}[/tex]

[tex]\mathbf{ (-6 - x)^2 = 3600}[/tex]

Take square roots of both sides

[tex]\mathbf{ -6 - x = 60}[/tex]

Add 6 to both sides

[tex]\mathbf{ - x = 60 + 6}[/tex]

[tex]\mathbf{ - x = 66}[/tex]

Multiply both sides by -1

[tex]\mathbf{ x = -66}[/tex]

Hence, the possible value of x is -66

Answer:

inequality: n/4 < -1

n < -4

Step-by-step explanation:

1. "The quotient of a number and 4" means that we're dividing a number, n, by 4: [tex]\frac{n}{4}[/tex]. "Less than -1" means that we have to use the < (less than) sign and put -1 after it. When we put these terms in a quantity, they look like this: [tex]\frac{n}{4} < -1[/tex].

2. Now, let's solve the inequality above.

Step 1: Multiply both sides by 4.

Therefore, the inequality is n/4 < -1, and the solution to that inequality is n < -4.

Answer:

a=3/5 or 0.6

Step-by-step explanation:

a-8/5-2/3a=-7/5

Step 1: Multiply both sides

15a-24-10a=-21

Step 2: Combine like terms

5a-24=-21

Step 3: Calculate and divide both sides by 5

5a=3

Solution:

a=3/5 or 0.6

Step-by-step explanation:

rewriting the third equation

[tex]4x - y + z = - 5 \\ - x + y - z = 5 \\ 2x - y - z = 1[/tex]

add to second equation to the first

[tex]4x - y + z = - 5 \\ + (- x + y - z )= 5 \\ = 3x = 0 \\ x = 0[/tex]

[tex] - y + z = - 5 \\ y - z = 5 \\ - y - z = 1[/tex]

I add third equation to the second

[tex]y - z = 5 \\ + ( - y - z) = 1 \\ = - 2z = 6 \\ z = - 3[/tex]

substitute z = -3 into either one of the other two equations and solve for y

[tex] - y + ( - 3) = - 5 \\ - y - 3 = - 5 \\ - y = - 2 \\ y = 2[/tex]

x = 0

y = 2

z = -3

Answer:

x=0,z=-3,y=2

Since a > 1, b cannot be greater than 15, hence the value of a can be 3, 4, 5, and 10

Given the expression 15x + 20=a(bx + c),

To get the value of a, we will need to factor out the given expression as shown:

15x + 20=a(bx + c)

15x + 20=abx + ac

Comparing both sides

15x = abx

15 = ab

a = 15/b

Since a > 1, b cannot be greater than 15

Hence the value of a can be 3, 4, 5, and 10

Answer:

Step-by-step explanation:

38,500-36,000=2,500

B. The difference in the starting salaries is $2,500.

D. Luisa will make more money in the first 8 years.

The required scenario are,
(1) The difference in the starting salaries is $2,500.
(2) Damon will make more money in the first 8 years.

Given that,
Luisa took a job in which her salary can be modeled by the exponential function y = 36.000(1.025)", where x is the number of years after she is hired. Damon took a job with a starting salary of $38.500 and yearly raises of $800.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,
According to the question,
Difference in starting salary = 38500 - 36000 = $2500
Luisa's salary after 8 years = $43862.50
Damon's salary after 8 years  = $45108.89

Thus, the required scenario is,
(1) The difference in the starting salaries is $2,500.
(2) Damon will make more money in the first 8 years.
