I don't need a fast answer, I need a thorough explanation, I am trying to advance in Math and I am learning on my own. I want to learn how to do this correctly. Thank you in advance, I Promise I will give brainliest if I am satisfied! (100 points just so you see you are loved (: )
Answer:
D
Step-by-step explanation:
We have the set:
[tex]\{(2, -3), (-1,0), (0, 4), (-1, 5), (4, -2)\}[/tex]
Remember that the domain for a set of values is simply the input values.
In other words, our domain will be all of our x-coordinates.
We can see that our x-coordinates are: 2, -1, 0, -1, and 4.
So, our domain is:
[tex]\{2, -1, 0, 4\}[/tex]
Note that we only write need to write the -1 once.
So, our answer is D.
And we're done!

Frank believes his bedroom wall measures 12 feet long.
He has a ruler that is 1? feet long.
He uses this ruler to measure his bedroom wall.
Which equation can be used to solve for T,
the number of times he will have to use the ruler to check the length of his bedroom wall?
A. 1? = 12T
B. 1? T = 12
C. 1? + T = 12
D. T – 1? = 12
Answer:
A
Step-by-step explanation:
Answer:
B. 1? T = 12
Step-by-step explanation:
Since the bedroom measures 12 feet long, the answer or the product should be 12 (12 only)
He uses “1?” to measure the bedroom, and we need to know HOW MUCH TIMES he uses it.
So, 1? T will be the equation since we need to know how much times he uses the ruler.

Match each circular flower bed on the left to its circumference and its area on the right. Some answer options on the right will not be used.
Answer:
Bed A --- Third Option
Bed B --- Fifth Option
Step-by-step explanation:
Flower Bed A)
The formula for circumference is:
[tex]C=2\pi r[/tex]
The diameter of A is 10 feet. So, its radius is 5 feet.
Substitute 5 for r. So, the circumference of Bed A is:
[tex]C=2\pi (5)=10\pi\text{ feet}[/tex]
The formula for the area of a circle is:
[tex]A=\pi r^2[/tex]
Substitute 5 for r:
[tex]A=\pi (5)^2[/tex]
Square and simplify:
[tex]A=25\pi \text{ square feet}[/tex]
So, the circumference of Bed A is 10π feet and its area is 25π square feet.
Therefore, match Bed A to the third option.
Flower Bed B)
The radius of Bed B is 6 feet. Again, we can use the circumference and area formulas. Substitute 6 for r for circumference:
[tex]C=2\pi (6)[/tex]
Multiply:
[tex]C=12\pi\text{ feet}[/tex]
Substitute 6 for r for the area formula:
[tex]A=\pi(6)^2[/tex]
Square and simplify:
[tex]A=36\pi\text{ square feet}[/tex]
So, Bed B has a 12π feet circumference and a 36π square feet area.
Therefore, match Bed B to the fifth option.
And we're done!

What is the difference
between an ordered
pair and coordinates?
Answer:A coordinate system is a two-dimensional number line
Step-by-step explanation:
A coordinate system is a two-dimensional number line, for example, two perpendicular number lines or axes. An ordered pair contains the coordinates of one point in the coordinate system. A point is named by its ordered pair of the form of (x,y
The difference between an ordered pair and coordinates will be;
''Coordinates are used in geometry, and when there are two coordinates, they are ordered pairs when both component are of the same type.''
What is Coordinates?
A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.
Given that;
There are an ordered pair and coordinates.
Now,
The difference between an ordered pair and coordinates will be;
''Coordinates are used in geometry, and when there are two coordinates, they are ordered pairs when both component are of the same type.''
And, An ordered pair contains the coordinates of one point in the coordinate system. A point is named by its ordered pair of the form of
(a, b) and a coordinate system is a two-dimensional number line.
Thus, The difference between an ordered pair and coordinates will be;
''Coordinates are used in geometry, and when there are two coordinates, they are ordered pairs when both component are of the same type.''

You are buying packages of beads to make bracelets. Each package costs $3 plus 7% tax. You have a gift card for $15, and you plan to use only the gift card to pay for the beads. Which function c(p) represents the total cost, where p represents the number of packages of beads you purchase? What is a reasonable domain?
A. c(p) = 3.21p − 15; {0, 1, 2, 3, 4}
B. c(p) = 3.21p; all nonnegative integers
C. c(p) = 0.07(3p − 15); all nonnegative integers
D. c(p) = 1.07(3p); all nonnegative integers
Answer:
A
Step-by-step explanation:
You must multiply the number your buying by the price then you need to multiply by 1.07 because you need 7% or .07 to get the tax but you want to add that to the old number so you need a 1 in front so the answer is c(p) = 1.07(3p) however you still need the $15 gift card so instead you add the 7% into the three dollars you are multiplying by the number then subtract the 15 dollars because you aren't really paying. The reasonable domain is 0 1 2 3 4 because the number 5 would be over the 15 dollar limit.

Answer: -17
A function is defined as a relation between a set of inputs having one output each.
The value of the function f(t) = -2t² + 1 at t = -3 is -17.
The domain of the function is -17.
The range of the function is -3.
What is a function?A function is defined as a relation between a set of inputs having one output each.
f(x) = x + 2
At x = 2,
f(2) = 2 + 2 = 4
Domain = 2
Range = 4
We have,
f(t) = -2t² + 1
We need to find for t = -3.
f (-3) = -2 ( -3 )² + 1
[ -3 x -3 = 9 ]
f (-3) = -2 x 9 + 1 = -18 + 1 = -17

what is y when the equation is x^2 - 3xy -4y^2 =0
Answer:
y = 1/8 (5 sqrt(x^2) - 3 x) or y = 1/8 (-3 x - 5 sqrt(x^2))
Step-by-step explanation:
Solve for y:
-4 y^2 - 3 x y + x^2 = 0
Hint: | Multiply both sides by a term to make the coefficient of y^2 positive.
Multiply both sides by -1:
4 y^2 + 3 x y - x^2 = 0
Hint: | Using the quadratic formula, solve for y.
y = (-3 x ± 5 sqrt(x^2))/8:
Answer: y = 1/8 (5 sqrt(x^2) - 3 x) or y = 1/8 (-3 x - 5 sqrt(x^2))

Determine the solution.
2x+y=4
4x-3y=7
Answer:
The answer is: (x , y) = (19/10 , 1/5)
Step-by-step explanation:
Solve the equation for y-
y = 4 - 2x
4x - 3y = 7
Substitute the given value of y into the equation-
4 x - 3 ( 4 - 2x ) = 7
Solve the equation for x-
x = 19/10
Substitute the given value of x into the equation y = 4 - 2x-
y= 4 - 2 * 19/10
Solve the equation for y-
y = 1/5
The possible solution of the system is the ordered pair ( x , y )-
( x , y ) = ( 19/10 , 1/5)
Check if the given ordered pair is the solution of the system of equations-
{2 * 19/10 + 1/5 =4
4 * 19/10 - 3*1/5 =7}
Simplify the equalities-
4 = 4
7 = 7
Since all equalities are proven true the ordered pair is the solution of the system-
( x , y) = (19/10, 1/5)
FINALLY haha the solution is: ( x , y ) = (19/10 , 1/5)
