Given:
Consider the below figure attached with this question.
The table represents a proportional relationship.
To find:
The missing value from the table.
Solution:
If y is proportional to x, then
[tex]y\propto x[/tex]
[tex]y=kx[/tex] ...(i)
Where, k is a constant of proportionality.
The relationship passes through the point (-3,-1). Substituting [tex]x=-3,y=-1[/tex] in (i), we get
[tex]-1=k(-3)[/tex]
[tex]\dfrac{-1}{-3}=k[/tex]
[tex]\dfrac{1}{3}=k[/tex]
Putting [tex]k=\dfrac{1}{3}[/tex] in (i), we get
[tex]y=\dfrac{1}{3}x[/tex] ...(ii)
We need to find the y-value for [tex]x=-12[/tex].
Substituting [tex]x=-12[/tex] in (ii), we get
[tex]y=\dfrac{1}{3}(-12)[/tex]
[tex]y=-4[/tex]
Therefore, the missing value in the table is -4. Hence, option D is correct.

A student sees a newspaper ad for an apartment that has 1330. How many square meters of area are there
Answer:
[tex]Area = 123.55 m^2[/tex]
Step-by-step explanation:
Given
[tex]Area = 1330ft^2[/tex]
Required
Convert to [tex]m^2[/tex]
To convert from square feet to square meter, we simply divide by 3.281^2
So, we have:
[tex]Area = \frac{1330}{3.281^2}m^2[/tex]
[tex]Area = \frac{1330}{10.765}m^2[/tex]
[tex]Area = 123.55 m^2[/tex]

Step-by-step explanation:
(5) The multiplicative inverse of a number n, is the number which when multiplied by n will give a result of 1 which is a multiplicative identity. The multiplicative inverse of a number is actually the reciprocal of that number. For example, the multiplicative inverse of n is 1/n. The multiplicative inverse of 5 is 1/5. The multiplicative inverse of 5/6 is 6/5.
Therefore, the multiplicative inverse of [tex]\frac{-11}{15}[/tex] is [tex]\frac{-15}{11}[/tex]
(6) To solve 7m + 12 = -4m + 78, follow these steps;
i. Collect like terms by putting terms with m on the left hand side and the terms without m on the right hand side as follows;
7m + 4m = 78 - 12
ii. Now solve both sides;
11m = 66
iii. Divide both sides by 11;
[tex]\frac{11m}{11} = \frac{66}{11}[/tex]
m = 6
(7) Let the number be x;
10 more than twice number is 22 implies that
10 + 2x = 22
Now solve the equation;
2x = 22 - 10
2x = 12
x = 6
(8) The interior angles of a given polygon are the angles of its vertices that are within or inside of the polygon.
The sum of the interior angles of a polygon is given by;
(n-2) x 180°
where;
n = number of sides of the polygon.
For example;
For a triangle, which has n = 3 sides, the sum of these interior angles is (3 - 2) x 180° = 180°
For a rectangle/square, which has n = 4 sides, the sum of these interior angles is (4 - 2) x 180° = 360°.
For a pentagon, which has n = 5 sides, the sum of these interior angles is (5 - 2) x 180° = 540°
Therefore, depending on the number of sides n, the sum of the interior angles of a given polygon is given by;
(n-2) x 180°

This exercise uses the population growth model. The population of a certain species of fish has a relative growth rate of 1.9% per year. It is estimated that the population in 2010 was 11 million. (a) Find an exponential model n(t)
Answer:
n(t) = 11e^0.019t
Step-by-step explanation:
The estimated population in 2010 = 11,000,000 = initial population
The growth rate = 1.9% per year = 1.9/100 =
The exponential growth model follows the general form :
n(t) = ae^rt
a = Initial population ; r = growth rate ; t = period
Hence, we have ;
n(t) = 11e^0.019t in millions

y = -4/7x +58/7
Step-by-step explanation:
The slope of the given line segment is ...
m = (y2 -y1)/(x2 -x1)
m = (17 -3)/(1 -(-7)) = 14/8 = 7/4
Then the slope of the perpendicular line is ...
-1/m = -4/7 . . . . . slope of the perpendicular bisector.
__
The midpoint of the given line segment is ...
M = 1/2(x1 +x2, y1 +y2)
M = (1/2)(-7 +1, 3 +17) = 1/2(-6, 20) = (-3, 10)
__
The y-intercept of the bisector can be found from ...
b = y -mx
b = 10 -(-4/7)(-3) = 10 -12/7 = 58/7
Then the slope-intercept form equation for the perpendicular bisector is ...
y = mx +b
y = -4/7x +58/7
The graphs below have the same shape. Complete the equation of the blue
graph. Enter exponents using the caret (-); for example, enter y as x^3. Do
not include "G(x) =" in your answer.
Answer:
The graphs below have the same shape. What is the equation of the blue graph? A. G(x) = (x + 3)^3 B. G(x) = x^3 + 3 C. G(x) = x^3 - 3 D. G(x) = (x - 3)^3
The blue graph is a horizontal shift to the left by 3 units of F(x) = x³.
G(x) = (x + 3)³.
What is translation?In mathematics, translation is the process of moving an object from one position to another without changing its shape, size, or orientation.
It involves sliding the object in a particular direction by a certain distance.
We have,
From the graph, the blue graph is G(x) = (x + 3)³.
The function f(x) = (x + 3)³ is a transformation of the function f(x) = x³.
Specifically, it is a horizontal shift to the left by 3 units.
To see why,
Let's consider the effect of replacing x with x + 3 in the original function f(x) = x³.
f(x + 3) = (x + 3)³
Notice that f(x + 3) is equal to f(x) translated horizontally to the left by 3 units.
For example, when x = 0, we have:
f(0) = 0³ = 0
f(0 + 3) = 3³ = 27
So the point (0, 0) on the graph of f(x) = x³ is transformed to the point
(-3, 27) on the graph of f(x) = (x + 3)³.
Similarly, we can see that every point on the graph of f(x) = x³ is shifted horizontally to the left by 3 units to obtain the graph of f(x) = (x + 3)³.
Therefore,
The blue graph is G(x) = (x + 3)³.

Answer:
547 500
Step-by-step explanation:
Interest for 1 year:
0.01%×365=3.65 a year
3.65×10=36.5% for 10 years
36.5×1,500,000÷100=547 500
The interest paid after 10 years is 547 ,500 Baht.
What is Interest ?Interest is the amount paid or earned when a loan is taken or an investment is done respectively.
It is given that
Principal = 1,500,000 Baht
Rate = 0.01 % per day

You play basketball at your school's

options. Option A is to buy a membership
card for $20 and pay $2 each time you
go to the gym, t. Option B is to pay $4
each time you go. Write a a linear
equation to show how many trips to the
gym would the cost be the same?
Answer:
20 + 2x = 4x
Step-by-step explanation:
So you are setting the two expressions equal to each other.
buying a membership card and paying each time looks like this: 20 + 2x where x is the number of times you go to the gym. 20 dollars base then 2 each time you go.
4 each time you go is just 4x
so just set the two equal to each other.
20 + 2x = 4x
If you solve it you will get x = something, which would be the number of times to make the two equal.
