Which equation has a constant of proportionality equal to 999? Choose 1 answer: Choose 1 answer: (Choice A) A y=\dfrac{81}{3}xy= 3 81 xy, equals, start fraction, 81, divided by, 3, end fraction, x (Choice B) B y=9xy=9xy, equals, 9, x (Choice C, Checked) C y=3xy=3xy, equals, 3, x (Choice D) D y=\dfrac{1}{9}xy= 9 1 x
Answer:
Option (D) is correct
Step-by-step explanation:
If y is a multiple of x and versa, it will have a constant of proportionality.
Option (A)
y = (81/3)xy
y will cancel out
1=27x
It is not correct
Option (B)
y=9xy
y will cancel out
1=9x
Option (C)
y=3xy
y will cancel out
1=3x
Option (D)
y = (1/9) x
y will cancel out
x=9y
In option (D), we see that x is 9 times of x. It means it has constant of proportionality equal to 9.
The equation y = 9x represents the constant of proportionality which is equal to 9.
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation can also be used to represent direct proportionality as -
y = mx
m = y/x
[m] is called constant of proportionality
We have the constant of proportionality equal to 9
The equation y = 9x represents the constant of proportionality which is equal to 9 as when compared with y = mx, we get m = 9.
Therefore, the equation y = 9x represents the constant of proportionality which is equal to 9.

A line graph titled Meals per Day has number of days on the x-axis, and number of meals prepared on the y-axis. At 5 days there are 30 meals prepared; at 10 days, 60 meals; at 15 days, 90 meals; at 20 days, 120 meals.
Use proportional reasoning to find the constant of proportionality for the relationship shown on the graph.
Answer:
6
Step-by-step explanation:
30 meals ÷ 5 days = 6
60 meals ÷ 10 days = 6
90 meals ÷ 15 days = 6
120 meals ÷ 20 days = 6
Constant of proportionality is 6.

What is mean by Cuboid?A cuboid is the solid shape or three-dimensional shape. A convex polyhedron which is bounded by six rectangular faces with eight vertices and twelve edges is called cuboid.
We have to given that;
The volume of the box is modeled by the function,
⇒ V (x) = 5x² + 5x
Now, At x = 4;
The volume of the box is,
⇒ V (x) = 5x² + 5x
⇒ V (4) = 5 × 4² + 5 × 4
⇒ V (4) = 5 × 16 + 20
⇒ V (4) = 80 + 20
⇒ V (4) = 100 cubic units

The sum of two numbers is x. If one of the numbers is 12, what is the other?
a. 12 x
b. 12 - x
c. 12 + x
d. x - 12
Answer:
D
Step-by-step explanation:
The question states that the sum of two numbers is x, and they give us one number which is 12. We know that 12 + 12x cannot equal x. We also know that 12 + 12 + x = x will cancel out the variable. Then, we can eliminate B, as the questions stated that the sum of two numbers is x, and they gave us one number of x. We know that the other number will be the unknown value minus 12, because 12 + x - 12 = x will simplify into x = x, which is true.

Write y - 4 = 1 ( x - 4) in slope intercept form.
Answer:
y=x
Step-by-step explanation:
First, distribute the 1 to the x and -4. Both of these when multiplied by one equal their original value, leaving you with y-4=x-4.
Then, to isolate the y, you add 4 to both sides. This leaves you with simply y=x.

What is the product of two odd numbers and a multiple of 2
An odd number is (2x) + 1
An even number is (2x)
These are the definitions.
Using the binomial (2x + 1)(2x + 1), we can see the properties of all products made from odd numbers.
Foiling will give 4x^2 + 4x + 1.
4x^2 is even because 4x^2 can be expressed as 2(2x) x 2(2x).
4x is even because 4x can be expressed as 2(2x)
This means that 4x^2 + 4x is even so the expression 4x^2 + 4x + 1 is odd because an even number + 1 is odd as shown by (2x) + 1.
This shows that every outcome of the product of 2 odd numbers will result being odd.
This means there is no answer to this problem, because any number that is a multiple of 2 is even. (Basically the definition of even)
Using even and odd numbers concepts, it is found that the product is an even number.
------------------------
An even number is a number that is divisible by 2.An odd number is a number that is not divisible by 2.------------------------
The product of two odd numbers will always generate an odd numbers, examples: [tex]3 \times 5 = 15, 3 \times 7 = 21, 3 \times 9 = 27[/tex]The product of an even number with an odd number will always be an even number, as examples: [tex]3 \times 4 = 12, 3 \times 6 = 18[/tex]------------------------

1/4 x 3
(in fraction form please)
Answer:
3/4
Step-by-step explanation:
1/4 x 3/1 = 3/4
Every whole number has a /1 under it! So when multiplying you do 1/4 x 3/1.
If you are confused, basically all you do is multiply 1 and 3 (numerators) then 4 and 1 (denominators)
The multiplication of 1/4 and 3 comes to be 3/4.
We know that every number has 1 in its denominator.
So, [tex]\frac{1}{4} *3[/tex] can be written as [tex]\frac{1}{4} *\frac{3}{1}[/tex]
How multiplication of two fractions take place?To multiply two fractions, multiply the numerator of the first fraction to the numerator of the second fraction followed by multiplication of the denominator of the first fraction to the denominator of the second fraction.
So, [tex]\frac{1}{4} *\frac{3}{1} = \frac{1*3}{4*1}[/tex]
[tex]\frac{1}{4} *\frac{3}{1} = \frac{3}{4}[/tex]
So, multiplication of 1/4 and 3 = 3/4
Therefore, the multiplication of 1/4 and 3 comes to be 3/4.

Monday
Tuesday
Step-by-step explanation:
Given the temperature data:
Mon _____ Tue _____ Wed _____ Thur ___ Fri
-2.5°F ___ - 1.9°F _____ 0°F _____ - 1.5°F _0.5°F
Days colder than - 1.75°F
Days colder than - 1.75°F are days whereby the temperature value is less than - 1.75
Hence,
-2.5°F < - 1.75°F = (Monday)
-1.9°F < - 1.75°F = (Tuesday)

The value of x after eliminating the variable y is -9.
What is an elimination method?The elimination method involves taking one variable out of the system of linear equations by using addition or subtraction along with multiplication or division of the variable coefficients.
Given that the two equations are 9x – 2y = – 75 and 2x – 2y = -12. The equations will be solved as,
9x – 2y = – 75
2x – 2y = -12
The value of x will be calculated by elimination of the variable y,
9x – 2y = – 75
-2x + 2y =+12
