15x=75Write which property of equality you used.
1) Given this equality,
15x = 75 Divide both sides by 15
x=5
2) Then we can write that since x = 5 and 15x = 75 we have here is the Division Property of Equality.
Because in this case, we divided both sides by 15, which is different from zero to find equivalent equality.
3) So
Find the x-and y-intercepts of the line:3x - 4y = 12A.x-int: (-4,0)y-int: (0,3)B. x-int: (4,0)y-int: (0, -3)C. x-int: (0,4)y-int:(-3,0)D. x-int: (0,-4)y-int: (3,0)
To find the x-intercept, simply but y=0 in the equation given and solve for x
That is;
3x - 4y = 12
3x - 4(0) = 12
3x = 12
Divide both-side of the equation by 3
x= 4
The x-intercept is;
(4, 0)
To find the y-intercept, simply put y=0 in the equation given and then solve for y
That is;
3x - 4y = 12
3(0) - 4y = 12
-4y = 12
Divide both-side of the equation by -4
y = -3
The y-intercept is (0, -3)
Hence, the correct option is B.
x-int: (4,0)
y-int: (0, -3)

the numbers between 1 to 2022 are written on a piece of paper.Caitlin circles the even numbers with red circles and nicole circles the multiples of 5 with yellow circles.How many numbers are circled with only one color?
The number of numbers circled with only one color found using arithmetic progression formula are 809 numbers
What is an arithmetic progression?An arithmetic progression is a sequence of numbers in which the difference between any two consecutive terms in the sequence is constant
The given parameters are;
The set of the numbers written on the paper = Numbers from 1 to 2022
Numbers circled with red circles by Caitlin = All even numbers between 1 and 2022
Numbers Nicole circles using yellow = Numbers that are multiples of 5
Required; The number of numbers that are circled with one colour only
Solution; The even numbers are numbers that are a multiple of 2
The number of even numbers between 1 and 2022 are found using arithmetic progression formula as follows;
[tex] a_{n} = a_{1} + (n - 1)\cdot d[/tex]
Where;
[tex]a_{1}[/tex] = The first term = 2 (First even number)
d = The common difference = 2
n = The number of terms
Given that 2022 is an even number, we have;
[tex] a_{n} = 2022 = 2 + (n - 1)\cdot 2[/tex]
Which gives;
[tex] \displaystyle {n = \frac{(2022 - 2)}{2} + 1 = 1011} [/tex]
We note that 10 is the lowest common multiple of 2 and 5, which gives;
Multiples of 10 have two colors, therefore, the numbers that have only one color is given by the difference between the number of even numbers and the number of multiples of 10 as follows;
The number of multiples of 10 are;
[tex] \displaystyle {n = \frac{(2020 - 10)}{10} + 1 = 202} [/tex]
Which gives;
The numbers having only one colour = 1011 - 202 = 809

Two similar boxes A and B are given with box B created by dividing box A's dimensions by 2.

Third-degree, with zeros of -2,-1, and 5, and a y-intercept of -10.
Answer:
y = x³ -2x² -13x -10
Step-by-step explanation:
You want a polynomial with x-intercepts -2, -1, and 5, and a y-intercept of -10.
Polynomial factorsA polynomial with zero x = p will have a factor of (x -p). The three given zeros mean factors of the desired polynomial will be ...

The water pressure on a submerged object is given by P = 64d, then the
a. The answer to the subject of the formula, "d," is d = P/64.
b. The depth of a submerged object if the pressure is 672 pounds per square foot is 10. 5 feet
A function can be defined as an expression, law or rule that shows the relationship between two variables.
These variables are namely;
Independent variableDependent variableGiven the role as;
P = 64d
Where;
P stands for pounds per square foot of pressure.
d represents the object's depth in feet.
Let's now make the variable "d" the focus of the formula.
The coefficient of the variable "d," which is 64, is used to divide both sides of the equation. So that the variable can stand on its own, this is done.
(a) We get,
P/64 = 64d/64
d = P/ 64
(b) P equals 672 pounds per square foot if there is pressure.
When the variable's value is substituted into the formula, we get;
d = P/64
Then,
d = 672/64
Discover the quotient,
d = 10. 5 ft.
The value is 10.5 feet .
Therefore,
a. The answer to the subject of the formula, "d," is d = P/64.
b. The depth of a submerged object if the pressure is 672 pounds per square foot is 10. 5 feet.

The graph (g-f)(x)=-4x complies with the query.
Graph example: What is it?An edge denotes the connection between the x and y vertices and is represented by the pair (x ,y). In the examples that follow, circles stand in for vertices and lines for edges.
The graph indicates that line generated by function f(x) passes through the points (1,-3) and (0,0) and that line similarly passes through the points (1,1) and (0,0).
With the use of the formula Y-Y1 = y2-y1/x2-x1, we can thus determine the equation of the lines (x-x2)
Therefore, the equation of the line produced by the function f(x) y+3= 3-0/0-1 (x-1)
Function f(x) Equals 3x since y+3=-3x+3 y=-3x.
the line drawn by the function g(x) has the equation y=x, hence function g(x)=x.
