C. As x decreases in value, y decreases in value. As x increases in value, y increases in value.
Which method can be used to find the end behavior of the graph?The given coordinates on the graph are;
(-3, 0), (0, 3), (2, 4), and (5, 5)
The coordinates of the starting point of the graph = (-3, 0)
Shape of the graph = Extends from point (-3, 0), upwards and to the right
Therefore;
As the x-value increases, the y-value increases and vice versa, with, x increasing faster than y.
However, given that the graph is for a square root function, the correct option is option C;
C. As x decreases in value, y decreases in value. As x increases in value, y increases in value.

A sales team estimates that the number of new phones it will sell is a function of the price that it sets. It estimates that if it
sets the price at.x dollars, it will sell f(x) = 2,712 - 3x phones. Therefore, the company's revenue is x (2,712 - 3x). Find
the price x that will maximize the company's revenue.
The price x which will maximize the company's revenue is 904
How to determine the priceThe price x which will maximize the company's revenue is 240
Let
Price of the good = x
Number of goods sold = 2712- 3x
The formula for revenue is given as;
Revenue = Price × Quantity
= x( 2712 - 3x)
Expand the bracket
2712x - 3x^2
Therefore, the price x which will maximize the company's revenue will be:
2712x - 3x^2 =0
Collect like terms
3x² = 2712x
3x = 2712
Divide both side by 3
3x/3 = 2712/3
x = 904

A mixed number is a mathematical representation of a number that consists of a whole number and a fraction. It's called a "mixed number" because it combines both a whole number and a proper fraction. The whole number part represents a whole quantity, while the fractional proportion represents a proportion of a whole.
Mixed numbers are generally employed to represent measures that aren't whole numbers but are still greater than 1. They're particularly useful when dealing with magnitudes, such as lengths or quantities of things, that concern both whole units and fractional parts.
Given that
[tex]7\dfrac{13}{100}[/tex] [tex]= 7 + \dfrac{13}{100}[/tex]
[tex]= \dfrac{700}{100}+ \dfrac{13}{100}\\= \dfrac{700+13}{100} \\= \dfrac{713}{100}[/tex]

What is a quadratic equation?
A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is ax²+ bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term.
-16t²+32t+5
by comparing this equation to the standard form of the quadratic equation we get
a=-16 b=32 c=5
the time (t) needed for the ball to reach its maximum height using the axis of symmetry formula (x = -b/2a) for a parabola:
the time at which the ball reaches the maximum height using the axis of symmetry formula is (x=-b/2a)
t = -32/2×-16
t=1sec
by putting h(t) to zero and determining the time (t) when the ball hits the ground:
-16t²+32t+5=0
-16(t²+2t+5/16)=0
t²-2t-5/16=0
(t)²-2×1×t+(1)²-5/16=1

What are the y-intercept and the asymptote of g(x) = 3x – 5? (0, –5); y = 3 (0, –2); y = 5 (0, –4); y = –5 (0, 5); y = –3
The y-intercept of the equation g(x) = 3^x - 5 is (0, -4) and the asymptote of the equation g(x) = 3^x - 5 is y = -5
How to determine the y-intercept?The equation of the function g(x) is given as:
g(x) = 3^x - 5
The y-intercept is a point on the graph where the value of x is 0
This is represented by x= 0 or (0, y)
This means that we substitute 0 for x in the above equation
So, we have:
g(0) = 3^0 - 5
Evaluate the exponent 3^0
g(0) = 1 - 5
Evaluate the difference of 1 and 5
g(0) = -4
Rewrite this point as
(0, -4)
This means that the y-intercept of the equation g(x) = 3^x - 5 is (0, -4)
How to determine the asymptote?The equation of the function g(x) is given as:
g(x) = 3^x - 5
The asymptote is a point on the graph where that is parallel to the graph
In the above equation, we have:
g(x) = 3^x - 5
Express the radical as 0
y = 0 - 5
Evaluate the difference of 0 and 5
y = -5
This means that the asymptote of the equation g(x) = 3^x - 5 is y = -5

Last night, the two dinner specials at Bob's favorite restaurant were salmon filet and filet mignon. The restaurant served 70 specials in all, 80% of which were salmon filets. How many filet mignon did the restaurant serve?
Based on the given parameters, the number of filet mignon the restaurant served is 14
How to determine the number of filet mignon the restaurant served?From the question, the given parameters are:
Dinner specials = salmon filet and filet mignon.
Dinner specials = 70 dinner specials
Salmon filets = 80%
This means that the proportion of filet mignon is
filet mignon = 100%- Salmon filets
This gives
filet mignon = 100%- 80%
Evaluate the difference
filet mignon = 20%
The number of filet mignon is calculated as:
filet mignon = 20% * Dinner specials
Substitute the known values in the above equation
filet mignon = 20% * 70
Express 20% as decimal
filet mignon = 0.20 * 70
Evaluate the product
filet mignon = 14
Hence, the number of filet mignon the restaurant served is 14
So, the complete parameters are:
Dinner specials = salmon filet and filet mignon.
Dinner specials = 70 dinner specials
Salmon filets = 80%

A team plays 93 games in a season. The team won 15
more than twice as many games as they lost.
How many wins and losses did the team have?
PLS HELPPPP THE WORDING IS CONFUSING
Answer:67 wins, 26 losses
Step-by-step explanation: They played 93 games. Let L = their losses and w = their wins. They won 15 more than twice as many games they lost so w = 2L + 15. So, 93 = 3L + 15. 93 - 15 = 78. 78 divided by 3 is 26 so they lost 26 games and won the rest of them or 93-26 = 67 wins and 26 losses.

Option D is correct, the proportion for corresponding sides is 12/4 = 24/8.
According to the statement
we have given that the two rectangle which are similar to each other and we have to find the correct proportion for corresponding sides of rectangles.
So, we know that the
For the two rectangles to be similar, it means the ratio of their corresponding sides must be the same.
Looking at the two rectangles, the corresponding sides are pf the rectangles are:
4 m side corresponds to 8 m side in rectangle A
12m side corresponds to the 24 m side in rectangle B.
Then
The ratios of the both rectangles are:
In rectangle A is 8/4 = 2
In rectangle B is 24/12 = 2
From this it is clear that the ratios are equal.
Thus, the scale factor is 2
Since 8/4 = 24/12, we can rearrange to get;
12/4 = 24/8.

3. Ying Yu turned 22 this year. In 8 years, she will be three times as old as her little brother will be then. How old is her little brother now? Answer
Answer:
He is 2 years old.
Step-by-step explanation:
She is 22, in 8 years she will be 30. 30 is 3×10. At that time, her brother will be 10; that is 8 years from now. So now, the little brother is 10-8 = 2 years old.
If you must show algebra work:
x = brother's age now.
x+8=brother's age in 8 years.
YingYu's age in 8 years = 3 × brother's age in 8 years
