The slope of the graph that models the amount Sarah owed after a given number of x months, represents the monthly payment Sarah makes to repay the loan
What is a monthly payment on a loan?Monthly payment on a loan is the payment made each month within the period specified in the loan, to repay the loan and the interest on the loan.
The given parameters of the graph are;
Information on the graph = The amount owed for a number of x months
Taking the y–axis (Vertical axis) of the graph as specifying the amount owed given in Dollars, and the x–axis as the number of months of payment, we have;
[tex] \displaystyle{Slope = \frac{\Delta y}{\Delta x}} [/tex]
Where;
∆y = Change in the amount Sarah owes
∆x = Change in the time
Which gives;
[tex] \displaystyle{Slope = \frac{Change\: in\: the\: amount \:owed}{Change\: in\: time }}[/tex]
Whereby the graph is a straight line graph, we have;
The slope = Constant
Therefore, the change in the amount owed over a given time frame such a month, is constant
Which gives;
The slope represents the amount by which the Sarah's student loan changes each month, which is equivalent to and therefore;
The amount Sarah repays each month (monthly payments on the loan) towards paying off the student loan.Learn more about calculating the monthly payment on a loan here:

Answer:x=32°
y=35°
Step-by-step explanation:
23°+32°+y=90°
55°+y=90°
y=35°
35°+23°+x=90°
58°+x=90°
x=32°
Answer:
Angle AOE = angle FOB = 32° (vertically opposite angles)
x = 32°
Since GH is a straight line, angle COH = angle COG = 90°
Angle BOD = angle COA = y° (vertically opposite angles)
y = 90-32-23 = 35°

The life expectancy of a new born kid increases at a rate of 1.5 years for every day the kid is alive during the first 60 days after being born. The expectancy reduces by 0.5 year for every day the kid is ill during these first 60 days. The initial life expectancy of a new born kid is 10 years. What is the life expectancy of a kid born on a Tuesday, after 37 days of being born (assume the kid is alive on the 37th day) if the kid falls ill on every Sunday?
The total life expectancy of the kid is 45.5 years.
rate of increase of life expectancy = 1.5 years per day
The rate of reduction of life expectancy = 0.5 years per day
37 days will mean ((7x5)+2), i.e., 5 complete weeks and 2 extra days.
Let the 2 extra days be Tuesday and Wednesday, now the 5 complete weeks will start from Thursday and after 37 days, the day will be Wednesday.
In this duration 5 Sundays will come on which the kid falls ill, so the reduction in life expectancy will be: 0.5 x 5= 2.5 years.
The remaining days will be: 37 - 5 = 32
So, the increase in life expectancy will be: 1.5 x 32= 48 years.
Thus, the total life expectancy of the kid is found to be : (48-2.5)years=45.5 years.

If this is an arithmetic sequence, each of the terms will have a common difference. Let's check.
[tex]\begin{gathered} 3-21=-18 \\ 21-147=-126 \end{gathered}[/tex]As we can see, each of the terms does not have a common difference. The first one is -18 while the other one is -126. Therefore, this is not an arithmetic sequence.
Now, let's check if this is a geometric sequence. If it is, each of the terms will have a common ratio.
[tex]\begin{gathered} 3\div21=\frac{1}{7} \\ 21\div147=\frac{1}{7} \end{gathered}[/tex]As we can see, each of the terms has a common ratio which is 1/7. Therefore, 147, 21, 3 is a geometric sequence and the common ratio is equal to 7.
A biased dice is rolled and the results are recorded in a table. The dice is rolled once more. a) Use the table to estimate the probability that a 3 will be rolled. b) If the dice is rolled another 500 times, how many sixes would you expect to roll? Score 1 2 3 4 5 6 Frequency 12 35 11 23 7 12
The probability that a 3 will be rolled would be 0.125 and the expected number of 6's roll would be 68.
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
The events' estimated probabilities are as follows, according to the exponential probability theory:
P(3) = 0. 125
P(6 in 500 rolls) = 68 rolls
Number of times event occurs / number of trials
A number of attempts = sum of frequency:
(12+35+11+23+7+12) = 88
So the probability that a 3 will be rolled as
⇒ number of 3's / number of attempts
⇒ 11/88 = 0.125
The number of 6's probable in 500 rolls
⇒ (12 /88) × 500
⇒ 68.18 = 68
Therefore, the expected number of 6's roll would be 68.

Answer:
y = 1/2x + 1/2
Step-by-step explanation:
I'm going to give me answer is gradient/slope form :
To work out the gradient we make a triangle from the line and do :
change in y / change in x
You should get 1/2
Now we have y=1/2x + c
to work out c we substitute a point from the line and solve for c :
Point (1 , 1)
1 = 1/2(1) + c
1 = 1/2 + c
c = 1/2
So our final answer is y = 1/2x + 1/2

Using the concept of the slope of a linear function, it is found that:
Pool A is filing up slower than Pool B because the slope of the graph for Pool A is less than that of the graph for Pool B.The slope of the graph tells you the unit rate in gallons per minute.What is a linear function?A linear function, in slope-intercept format, is modeled according to the following rule:
y = mx + b
In which:
The coefficient m is the slope of the function, which is the rate of change of the function, that is, the change in y divided by the change in x.The coefficient b is the y-intercept of the function, which is the the value of y when the function crosses the x-axis(x = 0).For this problem, we have that Pool B starts with significantly less water than Pool A, but their volumes get closer, meaning that Pool B fills faster and has a higher slope, that is, it fills more gallons per minute into the pool.

0, negative 2 + i StartRoot 3 EndRoot, negative 2 minus i StartRoot 3 EndRootWhat are the solutions to a cubic function?The solutions of a cubic function are given by the values at which the graph intersects the horizontal axis.
First Part
The graph showing the shaded region of the inequality is left out
Second part;
The given equation can be presented as follows;
4•x³ + 16•x² + 28•x = 0
Required;
To find all the solutions of the equation
Solution;
The solutions of the equation are given by the locations on the graph where the equation intersects the x–axis, which are therefore, the points where the function is equal to 0
The equation 4•x³ + 16•x² + 28•x = 0 can therefore be used to find the solution as follows;
4•x³ + 16•x² + 28•x = 0
x•(4•x² + 16•x + 28) = 0
x•(4)•(x² + 4•x + 7) = 0
x•(x² + 4•x + 7) = 0 ÷ (4) = 0
x•(x² + 4•x + 7) = 0
Which by the multiplicative identity of 0, gives;
x = 0 or x² + 4•x + 7 = 0Therefore;
x = 0 is a solution to the equation
The other solutions are found from the quadratic equation, x² + 4•x + 7 = 0, using the quadratic formula that gives the solution to the general quadratic equation, a•x² + b•x + c = 0, as follows;
[tex] \displaystyle{x = \frac{ - b \pm \sqrt{ {b}^{2} - 4 \times a \times c } }{2 \times a }}[/tex]
Comparing the general form of the quadratic equation to the quadratic equation from the question;
a•x² + b•x + c = 0
x² + 4•x + 7 = 0
Gives;
a = 1
b = 4
c = 7
Plugging in the above values of a, b, and c, we get;
[tex] \displaystyle{x = \frac{ - 4 \pm \sqrt{ {4}^{2} - 4 \times 1 \times 7 } }{2 \times 1} = \frac{ - 4 \pm 2 \cdot\sqrt{ - 3} }{2} }[/tex]
Which gives;
x = -2 ± √(-3) = -2 ± i•√(3)
The other solutions are therefore;
x = -2 + i•√(3) and x = -2 - i•√(3)The solutions of the equation, 4•x³ + 16•x² + 28•x = 0, are therefore;
x = 0, x = -2+i•√(3), and x = -2 - i•√(3)

Given:
A table with the given values of the function y=g(x).
To find the function that represents g(x), we substitute a value of x into the given options.
For:
g(x =3+2x:,:
Let x=3
[tex]\begin{gathered} g(x)=3+2x \\ =3+2(3) \\ =9 \end{gathered}[/tex]Based on the given table, the value g(x) is 24 when x=3. So g(x)=3+2x is not the function that represents g(x).
For
[tex]\begin{gathered} g(x)=3\cdot2x \\ =3\cdot2(3) \\ =18 \end{gathered}[/tex]The value of g(x) =18 when x=3, so this is not the function.
For g(x)=3x^2:
[tex]\begin{gathered} g(x)=3x^2 \\ =3(3)^2 \\ =27 \end{gathered}[/tex]Hence, this is not the function as well.
For g(x)=3(2)^x:
[tex]\begin{gathered} g(x)=3\cdot2^x \\ =3\cdot2^3 \\ =3(8) \\ g(x)=24 \end{gathered}[/tex]We can notice that when x=3, the value of g(x) =24 which is the same as the value of g(x) in the given table.
To double check this, we plug in the other values of x.
Therefore, the answer is:
[tex]g(x)=3\cdot2^x[/tex]Which is the better buy: 1 liter of soda for $1, or 1 gallon of soda for $4? Justify your answer.
