Answer:
1/4
Step-by-step explanation:
Create a chart 18 over 72 and x over 100
Now we multiply 18 by 100 to get 1800
We take that 1800 and divide it by 72 to get 25/100
We can simplify this to 1/4
I NEED HELP ON THE FIRST QUESTION ASAP!!!!!!!!
Answer to question 1 is [tex]\text{y} \le -\frac{2}{5}\text{x}+100[/tex]
=========================================================
Explanation:
The first task is to find the equation of the line through the given points in the table.
Pick any two points you want. I'll pick (0,100) and (50,80)
Determine the slope:
[tex](x_1,y_1) = (0,100) \text{ and } (x_2,y_2) = (50,80)\\\\m = \text{slope} = \frac{\text{rise}}{\text{run}} = \frac{\text{change in y}}{\text{change in x}}\\\\m = \frac{\text{y}_{2} - \text{y}_{1}}{\text{x}_{2} - \text{x}_{1}}\\\\m = \frac{80 - 100}{50 - 0}\\\\m = \frac{-20}{50}\\\\m = -\frac{2}{5}\\\\[/tex]
The slope is -2/5.
The y intercept is b = 100 because of the point (0,100)
We go from [tex]\text{y} = m\text{x}+b[/tex] to [tex]\text{y} = -\frac{2}{5}\text{x}+100[/tex]
Each point from the table is found on this line. For instance, let's check the point (140,44)
[tex]\text{y} = -\frac{2}{5}\text{x}+100\\\\44 = -\frac{2}{5}*140+100\\\\44 = -56+100\\\\44 = 44\\\\[/tex]
This confirms (140,44)
I'll let you check the other points.
------------------
Any point on the line mentioned represents a scenario where César spends all of the $50.
If he goes above the line, then he'll spend more than $50. If he goes below, he spends less than $50.
This means we want to shade the region below the boundary line [tex]\text{y} = -\frac{2}{5}\text{x}+100[/tex]
We'll replace the equal sign with a "less than or equal" sign
We arrive at [tex]\text{y} \le -\frac{2}{5}\text{x}+100[/tex] as the final answer to question 1.

Find the asymptotes, domain and range.
For the given function,
Vertical asymptote = -5/4
Horizontal asymptote = -5/4
Domain = (-∞,-5/4) ∪ (-5/4,∞)
Range = (-∞,-5/4) ∪ (-5/4,∞)
What is a function?
A function in mathematics from a set X to a set Y allocates exactly one element of Y to each element of X. The sets X and Y are collectively referred to as the function's domain and codomain, respectively.
The given function is
[tex]f(x) = \frac{-5x+2}{4x+5}[/tex]
The given function has a vertical asymptote at x = -5/4. This is because the function tends to ∞ as x tends to -5/4.
The horizontal asymptote of the function is when x tends to ∞ .
[tex]\lim_{x \to \infty} \frac{-5x+2}{4x+5} = \frac{-5+2/x}{4+5/x} = \frac{-5}{4}[/tex]
The horizontal asymptote of function is at y = -5/4.
Since at x = -5/4, the function becomes undefined.
The domain is all real numbers except x = -5/4
Domain = (-∞,-5/4) ∪ (-5/4,∞)
Since the function is not defined at y = -5/4 as well, the range is also
(-∞,-5/4) ∪ (-5/4,∞) .
Therefore for the given function,
Vertical asymptote = -5/4
Horizontal asymptote = -5/4
Domain = (-∞,-5/4) ∪ (-5/4,∞)
Range = (-∞,-5/4) ∪ (-5/4,∞)

Three numbers are given below. Use prime factorisation to determine the HCF and LCM 1848, 132 and 462
Answer:
The HCF is the highest common factor of 1848, 132 and 462, which is 14.Step-by-step explanation:
Prime factorisation is a mathematical method that breaks a number down into its prime factors, the smallest positive integers that are multiples of that number.The highest common factor of 1848, 132 and 462 is the smallest number that divides all three.The lowest common multiple is the smallest number that multiples all three numbers!a man travels from Nigeria to Ghana by air and from Ghana to Liberia by ship .he returns by the same means he has 6 airlines and 4 shipping lines to choose from .in how many ways can he make his journey without using the same airline or shipping line
There will be 360 different ways without using the same airline or shipping line.
What is a combination?A combination in mathematics is a selection of items from a set with distinct members, where the order of selection is irrelevant.
Let's first consider the number of ways the man can choose his outbound journey. He has 6 airlines to choose from, and once he has made his choice of airline, he has 4 shipping lines to choose from.
Therefore, there are 6 × 4 = 24 ways he can choose his outbound journey.
For his return journey, he cannot use the same airline or shipping line that he used for his outbound journey.
This means he now has 5 airlines and 3 shipping lines to choose from. Therefore, there are 5 × 3 = 15 ways he can choose his return journey.
The total number of ways he can make his journey is:
24 × 15 = 360
Therefore, he can make his journey in 360 different ways without using the same airline or shipping line.

{10x + 7y= - 12
9x+ 5y = -16
Answer: x=-4, y=4
Step-by-step explanation:
We can use elimination method to solve this problem.
Let's eliminate y.
In equation 2, use the coefficient of y (i.e 5) to multiply equation 1. DO the same for other equation. Thus,
5(10x+7y=-12)
7(9x+5y=-16)
=> 50x+35y=-60
63x+35y= -112
clearly, y can be eliminated by subtraction.
Therefore,
-13x = 52 [-63+50 and 112-60)]
x = -4.
When x = -4,
9x+5y =-16
9(-4) +5y =-16
5y = 36-16
y=4.

What is terminal value formula ?
The terminal value formula helps estimate the value of a business beyond the explicit forecast period,
the terminal value formula = FCFF 6 / (WACC – Growth Rate)
We can say that in a DCF model with a five-year free cash flow projection, the terminal value formula = FCFF 6 / (WACC – Growth Rate)
It could be accountable that in finance, the terminal value (also known as “continuing value” or “horizon value” or "TV") of a security is the present value at a future point in time of all future cash flows when we expect stable growth rate forever. It is most likely often used in multi-stage discounted cash flow analysis and also allows for the limitation of cash flow projections to a several-year period; see Forecast period (finance). Forecasting results beyond such a period is impractical and exposes such projections to a variety of risks limiting their validity, primarily the great uncertainty involved in predicting industry and macroeconomic conditions beyond a few years.

5x - 2x + 1 = 10
2.) Subtract 1 from both sides to get 1 to the other side
5x - 2x = 10 - 1
3.) Combine like terms
3x = 9
4.) Divide 3 on each side to get x by itself
x = 3
