Nikhil and Mae work at the same company. Nikhil has been at the company 4 times as long as Mae. Nikhil's time at the company is 8 more than 2 times Mae's time. The following system of equations models the scenario: x = 4y x = 8 + 2y How many years has each person been employed by the company? Nikhil has been with the company for 16 years, while Mae has been there for 4 years. Nikhil has been with the company for 24 years, while Mae has been there for 6 years. Nikhil has been with the company for 20 years, while Mae has been there for 5 years. Nikhil has been with the company for 12 years, while Mae has been there for 3 years
The number of years of employment is A. Nikhil has been with the company for 16 years, while Mae has been there for 4 years.
How to find the years of employment ?The system of equations given is:
x = 4y
x = 8 + 2y
You can solve the system by setting the two expressions for x equal to each other:
4y = 8 + 2y
2y = 8
2y / 2 = 8 / 2
y = 4
Substitute y = 4 into the first equation to solve for x:
x = 4 x 4
= 16
So, Mae (y) has been at the company for 4 years and Nikhil (x) has been at the company for 16 years.

Annika's older cousin borrowed $800 to repair her car. she will pay off the loan after 2 years by paying back the principal plus 4.5% simple interest each year. How much will she spend in interest? How much will she pay back altogether?
Answer:
The equation below is provided:
$800 = principal amount borrowed/loaned
4.5% = interest per year
2 years = terms of payment
You need to know how much is the interest per year.
$800 * 4.5% = $36
Then, multiply the amount to the terms of payment to know the total amount of the interest to be paid.
$36 * 2 years = $72
The correct answer for the amount that Anika will spend for the interest is $72.

Answer:
We can start by isolating the variable x in the inequality:
(x/4) + 2 > -3
(x/4) > -5
Multiplying both sides by -4 (and flipping the inequality since we are multiplying by a negative number) gives:
x < 20
So any value of x that is less than 20 satisfies the inequality. Therefore, the possible solutions from the list below are:

Evaluate the Piecewise Function. Please Hurry
The value of piecewise function at x = -1 is f(-1) = 11, and the value of piecewise function at x = 9 is f(9) = 1.
what is piecewise function?
A piecewise-defined function in mathematics is one that is composed of several smaller functions, each of which has a specific interval of the domain it applies to. Instead of being a property of the function itself, piecewise definition is a way to express the function.
We have to evaluate the piecewise function for x = -1 and x = 9.
Let, function has value for x = -1 in the domain x ≤ 5 which is 11.
And function has value for x = 9 in the domain 6 < x which is 1.
⇒ f(-1) = 11 and f(9) = 1
Hence, the value of piecewise function at x = -1 is f(-1) = 11, and the value of piecewise function at x = 9 is f(9) = 1.

when pizza paradise first opened their business in 2010, they decided on a price for their large cheese pizza. after their first full year in business, they decided they woulds increase the price at a constant rate each year for four years. the new price in 2011, after their first increase was
$7.75. the price in 2014 was $10. Represent the situation with a table, graph and equation., what was the original price fro a large chew pi IN 2010? What is the slope of the line and what does it mean in the context of the story and what is the y-intercept (or vertical intercept)
of the line and what does it represent in the context of the story.
Using the equation 7.75 + 3x = 10 the prices for pizza is -
In 2010 - $7
In 2011 - $7.75
In 2012 - $8.5
In 2013 - $9.25
In 2014 - $10
What is an equation?
A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").
Pizza Paradise started in 2010.
The price in 2011 was increased at it was = $7.75
After 3 years on increasing the price at constant rate in 2014 the price was = $10.
Let the original price of pizza in 2010 be increased by a rate x.
Since the price increased is constant, so the equation will be linear.
The linear equation is -
7.75 + 3x = 10 3x = 10 - 7.75
x = 2.25 / 3
x = 0.75
So, price is increased every year by $0.75.
The original price of the pizza in 2010 was -
7.75 - 0.75 = $7
The price of the pizza in 2012 was -
7.75 + 0.75 = $8.5
The price of the pizza in 2013 was -
7.75 + 2(0.75) = $9.25
So, the equation becomes -
y = 0.75x + 6.25
The slope of the line m = 0.75 suggests the increase in price at a constant rate of $0.75.
The y-intercept b = 6.25 is the constant value. Tis means the lowest price of pizza is $6.25.
The graph of the equation is plotted.
Therefore, the price is increased every year by $0.75.

I need help on finding the slope from a table
To find the slope of the line represented on the given table we take two points and divide the difference on the y-axis by the difference on the x-axis:
\(\text{Slope}=\frac{3-3}{0-2}=\frac{0}{-2}=0\)The slope of the given line is 0. This means that it is parallel to the x axis.
We are going to graph the points given in the table:
Now let's connect the points:
The slope can be seen as the number of units that the line goes up or down when moving one unit to the right.
In this case, if we start from any value of x and move one unit to the right, the line does not rise or fall, so its slope is 0.

[hint: find the unpaid balance after 12 payments and after 24 payments.
Answer:
Monthly Loan Payment
Loan Amount (P) = $6,000
Monthly Interest Rate (n) = 0.75% per month [9.00% / 12 Months]
Number of months (n) = 36 Months [3 Years x 12 months]
Monthly Loan Payment = [P x {r (1+r)n} ] / [( 1+r)n – 1]
= [$6,000 x {0.0075 x (1 + 0.0075)36}] / [(1 + 0.0075)36 – 1]
= [$6,000 x {0.0075 x 1.308645}] / [1.308645 – 1]

Work out the size of each unknown exterior angle in this polygon. X =?
Answer:
see explanation
Step-by-step explanation:
the exterior angle of the interior angle 110° is
180° - 110° = 70°
the sum of the exterior angles of a polygon = 360°
sum the exterior angles and equate to 360
2x - 50 + x + 40 + x + 2x + 70 = 360
6x + 60 = 360 ( subtract 60 from both sides )
6x = 300 (divide both sides by 6 )
x = 50
then exterior angles are
2x - 50 = 2(50) - 50 = 100 - 50 = 50°
x + 40 = 50 + 40 = 90°
x = 50°
2x = 2 × 50 = 100°

Suppose the weather at Chebyshev Citadel is either sunny or cloudy. A sunny day is followed by a sunny day with probability 0.7, and a cloudy day is followed by a sunny day with probability 0.5. If it is sunny today, what is the probability that it will be sunny 3 days later
Answer:
0.628
Step-by-step explanation:
From the information given:
Let S represent sunny days and C represent cloudy days;
S is expressed in the matrix to be in the first row and first column
C is expressed in the matrix to be in the second row and second column
Then, the transition for the probability matrix can be computed as follows:
\(P = \right. \left[\begin{array}{cc}0.7&0.3\\0.5&0.5\\\end{array}\right]\)
\(P^2 = \right. \left[\begin{array}{cc}0.7&0.3\\0.5&0.5\\\end{array}\right] \right. \left[\begin{array}{cc}0.7&0.3\\0.5&0.5\\\end{array}\right]\)
\(P^2 = \right. \left[\begin{array}{cc}0.49+0.15&0.21+0.15\\0.35+0.25&0.15+0.25\\\end{array}\right] \right.\)
\(P^2 = \right. \left[\begin{array}{cc}0.64&0.36\\0.60&0.40\\\end{array}\right] \right.\)
\(P^3 = \right. \left[\begin{array}{cc}0.64&0.36\\0.60&0.40\\\end{array}\right] \right. \right. \left[\begin{array}{cc}0.7&0.3\\0.5&0.5\\\end{array}\right]\)
\(P^3 = \right. \left[\begin{array}{cc}0.628&0.372\\0.62&0.38\\\end{array}\right] \right.\)
So, if it is sunny, the probability that it is going to be sunny 3 days later = 0.628
Using the transition of the events, it is found that there is a 0.628 = 62.8% probability that it will be sunny 3 days later.
The transition of events, considering that it is sunny today and we want it to be sunny 3 days later, is given by:
S - S - S - S
S - C - S - S
S - S - C - S
S - C - C - S
Considering the probabilities stated in the exercise(S - S: 0.7, S - C: 0.3, C - S: 0.5, C - C: 0.5), for the last three days, the probability is:
\(p = 0.7^3 + 0.3(0.5)(0.7) + 0.7(0.3)(0.5) + 0.3(0.5)(0.5) = 0.628\)
0.628 = 62.8% probability that it will be sunny 3 days later.

Thomas and Randy had some blue and yellow handkerchiefs. 1/4 of Thomas' handkerchief and 3/7 of Randy's handkerchiefs are blue. Thomas and Randy have the same amount of yellow handkerchiefs. If the difference between the number of handkerchiefs they have is 10, how many handkerchiefs do they have in total?
Answer:
74 handkerchief
Step-by-step explanation:
Let the number of Thomas' and Randy's handkerchief be T and R respectively.
Thomas
blue ----- ¼T
yellow ----- 1T -¼T= ¾T
Randy
blue ----- \( \frac{3}{7} \)R
yellow ----- \( \frac{4}{7} \)R
Since they have the same number of yellow handkerchiefs,
¾T= 4/7 R
Multiply by 28 on both sides,
(since 28 is the lowest common multiple of 4 and 7)
21T= 16R -----(1)
From this we can see that R is greater than T.
Hence, given that the difference between R and T is 10,
R= T +10 -----(2)
Subst. (2) into (1):
21T= 16 (T +10)
21T= 16T +160 (expand)
21T -16T= 160
5T= 160 (simplify)
T= 160 ÷5 (÷5 on both sides)
T= 32
Subst. into (2):
R= 32 +10
R= 42
Thus, total number of handkerchief
