Answer:
The ordered pair (15, 12) means that 15 pounds of beans cost $12.
Step-by-step explanation:
Ordered pairs are in the format of (x,y). The first number represents a point's position on the x-axis and the second represents a point's position on the y-axis. Also note that in this graph, the x-axis represents the weight of beans in pounds and the y-axis represents the cost of beans.
Knowing this, (15,12) means that 15 pounds of beans must cost $12.
X/10*0.24-15.5/7.5=9
Given :
[tex](\dfrac{X}{10}\times 0.24 )- \dfrac{15.5}{7.5} = 9\\\\[/tex]
To Find :
The value of x.
Solution :
[tex](\dfrac{X}{10}\times 0.24 )- \dfrac{15.5}{7.5} = 9\\\\(\dfrac{X}{10}\times 0.24 ) = 9 + \dfrac{15.5}{7.5}\\\\(\dfrac{X}{10}\times 0.24 ) = \dfrac{(9\times 7.5 )+ 15.5}{7.5}\\\\(\dfrac{X}{10}\times 0.24 ) = \dfrac{83}{7.5}\\\\X = \dfrac{83\times 10}{7.5\times 0.24}\\\\X = 461.11[/tex]
Therefore, the value of X is 461.11 .

Use quadratic regression to find the
equation for the parabola going
through these 3 points.
(2, 19) (6, 99) (-1, 1)
y=[?]^2+[?]x+[?]
Answer:
The standard form of the parabola is
y = 2 x² + 4 x + 3
Step-by-step explanation:
Step(i):-
The standard form of the parabola
y = a x² + b x + c ...(i)
The equation for the parabola is passing through the point (2 , 19 )
19 = 4a + 2b +c ...(ii)
The equation for the parabola is passing through the point (6 , 99 )
99 = 36a + 6b +c ...(iii)
The equation for the parabola is passing through the point (-1,1) )
1 = a - b + c ...(iv)
step(ii):-
subtracting (ii) and (iii) , we get
8a + b = 20 ...(a)
Subtracting (iii) and (iv) , we get
5a + b = 14 ...(b)
solving (a) and (b) , we get
subtracting (a) and (b) , we get
8a + b-( 5a + b ) = 20 - 14
3 a = 6
a = 2
substitute a=2 in equation (a) , we get
8a + b = 20
8(2) + b = 20
b =20 -16
b = 4
Substitute a= 2 ,b = 4 in equation (ii) , we get
19 = 4a + 2b +c
19 = 8 + 8 + C
c = 19 -16 = 3
Final answer:-
The standard form of the parabola is
y = 2 x² + 4 x + 3

Answer:
Angle S
Step-by-step explanation:
The angle is always proportional to the opposite side. Angle opposite to the longest side has the largest angle so since Side RT is the shortest side, the angle opposite to it (or whatever the correct term is) would be Angle S.
3.0450 x 10^4 as an ordinary number
Answer:
30450 is the answer.
Step-by-step explanation:
Given number is [tex]3.0450 \times 10^4[/tex].
We need to write it as an ordinate number.
It is 3.0450 times 10 to the power 4.
It would mean that,
[tex]3.0450 \times 10^4=3.0450 \times 10000\\\\=\dfrac{3.0450 }{10000}\times 10000\\\\=30450[/tex]
Hence, the required answer is 30450.

Which statement best describes the function below?
f(x)= x3 - X2-9x+9
O A. It is not a function.
OB. It fails the vertical line test.
O C. It is a one-to-one function.
O D. It is a many-to-one function.
pls help!!
Answer:
D. It is a many-to-one functionStep-by-step explanation:
One-to-one if every y value has exactly one x value mapped onto itMany-to-one if there are y values that have more than one x value mapped onto them.We have a function that is of degree 3, so it has 3 x-intercepts which means there are points (x₁, 0), (x₂, 0), (x₃, 0), so it is a many-to-one function
Correct option is D
Find the distance between the two points in simplest radical form.
(-9,8) and (-3, -1)
Answer:
The distance between (-9, 8) and (-3, -1) will be:
[tex]\:d=3\sqrt{13}[/tex] units
Step-by-step explanation:
Given the points
(-9, 8)(-3, -1)Finding the distance between (-9, 8) and (-3, -1)
[tex]d\:=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]
[tex]=\sqrt{\left(-3-\left(-9\right)\right)^2+\left(-1-8\right)^2}[/tex]
[tex]=\sqrt{\left(-3+9\right)^2+\left(-1-8\right)^2}[/tex]
[tex]=\sqrt{36+81}[/tex]
[tex]=\sqrt{117}[/tex]
[tex]=3\sqrt{13}[/tex] units
Therefore, the distance between (-9, 8) and (-3, -1) will be:

The grocery store has 20% off from the original price on cereal. The equation for finding the sale price would be y = x - (.20x). What is the sale price if the cereal cost $3.00?
$2.20
$2.50
$2.40
$2.30
Step-by-step explanation:
y = x - 0.2x
y = 0.8x
When x = $3.00, y = (0.8)($3.00) = $2.40.
The sale price is $2.40.
Answer:
$2.40
Step-by-step explanation:
y = x - 20% of x
where x is $3.00
20% would be 1/5 of 3.00 = 3/5
3 - 3/5 = 15-3/5 = 12/5 = $2.40
Explain how the applications of inventory management for fixed quantities differ from those for fixed time periods. Give specific instances in which you would use a fixed time period model rather than a fixed quantity model. Provide real-world examples.
Answer:
The main difference between the fixed quantity and fixed time period is that the fixed quantity makes it mandatory for a fixed number of items to be ordered every time an order is made, while the fixed time period has a fixed period orders are received before the next order period.
Step-by-step explanation:
The fixed quantity model is adopted by producers of a product to maintain a package type and also to maximize the profit derived from sales. For example is when ordering or buying eggs from a store, the buyer cannot purchase five eggs since it is packaged in a dozen (12), and so must buy the whole package.
The fixed time model uses time intervals to receive and accumulate orders before delivery is made for every order interval.

Answer:
The value of x = -22
Step-by-step explanation:
Given the expression
[tex]-0.57x+0.27x=6.6[/tex]
Add similar elements: [tex]-0.57x+0.27x=-0.3x[/tex]
[tex]-0.3x=6.6[/tex]
Multiply both sides by 10
[tex]-0.3x\cdot \:10=6.6\cdot \:10[/tex]
Refine
[tex]-3x=66[/tex]
Divide both sides by -3
[tex]\frac{-3x}{-3}=\frac{66}{-3}[/tex]
[tex]x=-22[/tex]
Therefore, the value of x = -22

Answer:
a) -1
Step-by-step explanation:
Slope is also known as the gradient
1. assign a value to x and solve for y:
when x = 2, y = 2
when x = 4, y = 0
2. Next, use the equation of a straight line to find the gradient
y = mx + c
y is the y-coordinate, m is the gradient, x is the x-coordinate, c is the point where the line crosses the y-axis, which is found by equating y to 0 and solving for x
so y = mx + c becomes 2 = m*2 + 4, which then becomes 2 = 2m + 4
2m = -2 (take 4 away from 2)
m = -1
