The equation of f(x) is f(x)= −43x−3, the correct option is C.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.
Linear function is a function whose graph is a straight line
We are given that;
f(x) = -3/X-1
Now,
To find the equation of f(x), we need to identify the slope and the y-intercept of the line. The slope is the ratio of the vertical change to the horizontal change between any two points on the line. The y-intercept is the value of f(x) when x = 0.
Looking at the graph, we can see that f(x) passes through the points (-8, 3) and (0, -3). The slope can be calculated as:
slope=run rise= 0−(−8) f(0)−f(−8)=0+8−3−3=8−6=−43
The y-intercept can be found by plugging in x = 0 into the equation f(x) = slope x + y-intercept and solving for y-intercept:
f(0)=−43x0 + y-intercept
−3=y-intercept
Therefore, by the given function the answer will be f(x)=−43x−3.

Why is simple interest simple and when is it used?
Answer:
Simple interest is the cost of using or borrowing money without compound interest or interest on interest. Simple interest works in your favor when you're a borrower because it keeps the overall amount that you pay lower than it would be with compound interest
Step-by-step explanation:
Answer:
Simple Interest is considered "Simple" due to it's straight-forward method; where you add your annual interest rate (%) to your initial principal value, instead of compound which you add your annual interest rate (%) onto your new principal value.
Simple interest is usually used to calculate their first year interest ($).

An oil tank has to be drained for maintenance. The tank is shaped like a cylinder that is 3.5 ft long with a diameter of 1.8 ft. Suppose oil is drained at a rate of
1.7 n' per minute. If the tank starts completely full, how many minutes will it take to empty the tank?
Use the value 3.14 for at, and round your answer to the nearest minute. Do not round any intermediate computations.
Answer:
5 minutes
Step-by-step explanation:
Volume of cylinder = πr²h
Radius, r = diameter / 2 = 1.8 /2 = 0.9
Volume of cylinder = 3.14 * 0.9² * 3.5
Volume = 8.9019 feet³
Drain rate = 1.7 ft per minute
Volume / drain rate
8.9019 / 1.7
= 5.2364117
= 5 minutes (nearest minute)
we believe that 42% of freshmen do not visit their counselors regularly. For this year, you would like to obtain a new sample to estimate the proportiton of freshmen who do not visit their counselors regularly. You would like to be 98% confident that your estimate is within 3.5% of the true population proportion. How large of a sample size is required
Answer:
A sample of 1077 is required.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is of:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
42% of freshmen do not visit their counselors regularly.
This means that [tex]\pi = 0.42[/tex]
98% confidence level
So [tex]\alpha = 0.02[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.02}{2} = 0.99[/tex], so [tex]Z = 2.327[/tex].
How large of a sample size is required?
A sample size of n is required, and n is found when M = 0.035. So
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.035 = 2.327\sqrt{\frac{0.42*0.58}{n}}[/tex]
[tex]0.035\sqrt{n} = 2.327\sqrt{0.42*0.58}[/tex]
[tex]\sqrt{n} = \frac{2.327\sqrt{0.42*0.58}}{0.035}[/tex]
[tex](\sqrt{n})^2 = (\frac{2.327\sqrt{0.42*0.58}}{0.035})^2[/tex]
[tex]n = 1076.8[/tex]

Answer:
It should still be the same point.
Step-by-step explanation:
It should still be the same point, since the line did not increase in length, but the numbers of units has, and that does not affect the position of the half of the line.

Step-by-step explanation:
[tex] {x}^{2} - 5x - 2 = 0 \\ a = 1 \: and \: b = - 5 \: and \: c = - 2 \\ x = \frac{ - b± \sqrt{ {b}^{2} - 4ac } }{2a} \\ x = \frac{ - ( - 5)± \sqrt{ {( - 5)}^{2} - (4 \times 1 \times - 2)} }{(2 \times 1)} \\ x = \frac{5± \sqrt{33} }{2} \\ either : x = \frac{5 + \sqrt{33} }{2} \: or \: \frac{5 - \sqrt{33} }{2} \\ x = 5.4 \: or \: - 0.4[/tex]
The exact solutions of the equation x² - 5x - 2 = 0 are:
x = (5 + √(33)) / 2
x = (5 - √(33)) / 2
What is a solution?Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.
We also find the solution in a system of equations using the substitution or elimination method.
Example:
2x + 4 = 8
The solution is x = 2.
We have,
The quadratic formula is:
x = (-b ± √(b² - 4ac)) / 2a
For the equation x² - 5x - 2 = 0, we have:
a = 1, b = -5, c = -2
Substituting these values into the quadratic formula, we get:
x = (-(-5) ± √((-5)² - 4(1)(-2))) / 2(1)
Simplifying the expression inside the square root:
x = (5 ± √(33)) / 2
Therefore,
The exact solutions of the equation x² - 5x - 2 = 0 are:
x = (5 + √(33)) / 2
x = (5 - √(33)) / 2

$40,000 is invested at a rate of 5.7% that is compounded semiannually.
How much money is in the account after 17 years?
Answer:
$[tex]$78760.00[/tex]
Step-by-step explanation:
You want to calculate the interest on $40000 at 5.7% interest per year after 17 years.
The formula we'll use for this is the simple interest formula, or:
[tex]I=P*r*t[/tex]
Where:
P is principal amount, $40,000r is the interest rate, 5.7% per year, or in decimal form, [tex]\frac{5.7}{100} =0.057[/tex]t is the time involved, 17 yearsTo find the simple interest we multiply [tex]40000*0.057*17[/tex] to get
The interest rate is $38,760
Usually now, the interest is added onto the principal to figure some new amount after 17 years.
or 40000.00 + 38760.00 = 78760.00
=$78,760

(4x + 1)°
43°
PLEASE SOMEONE ONE HELPPPP!!
Answer:
x= 34
Step-by-step explanation:
(4x + 1 )° + 43° = 180° (due to linear pair)
4x+1+43 = 180
4x + 44 = 180
4x = 180 - 44
4x = 136
x = 136 ÷ 4
therefore, x = 34
