Answer:
[(1.2).(2,3), (3,4),(4.5))
Step-by-step explanation:
once reversed, no x-values repeat therefore these ordered pairs would represent a function.
hope this helped!
The last set of ordered pairs, [tex]\{(1.2),(2,3), (3,4),(4.5)\}[/tex], would still be a function even if its x- and y-coordinates where reversed.
Reversing the x- and y-coordinates is like finding the inverse relation.
An inverse relation will be a function if the original function were one-to-one. The only set of ordered pairs that satisfies this condition is
[tex]\{(1.2),(2,3), (3,4),(4.5)\}[/tex]
The other options are many-to-one relations. On reversing their x- and y-coordinates, they each become one-to-many relations. All functions are either one-to-one, or many-to-one.
So, the answer is the last set of ordered pairs [tex]\{(1.2),(2,3), (3,4),(4.5)\}[/tex]

A triangle with vertices at (1,1), (1,-3), and (3,-3) is acute. In complete sentences, explain whether this statement is true or false, and explain why?
9514 1404 393
Answer:
False; the triangle is "right"
Step-by-step explanation:
The segments lying on lines x=1 and y=-3 make a right angle with each other. The triangle is a right triangle, not an acute triangle.
Find the missing length of the right triangle.
a
21
35
Answer:
28
Step-by-step explanation:
Use the pythagorean theorem and solve for a:
a² + b² = c²
a² + 21² = 35²
a² + 441 = 1225
a² = 784
a = 28
So, the missing length is 28.
Question 7 of 25 Which of the binomials below is a factor of this trinomial? x - 6x-16 O A. X-1 O B. X-8 OC. X-16 O D. x-2
Answer:
(x-8) is the factor.
Step-by-step explanation:
The given trinomial is [tex]x^{2}-6x-16[/tex].
We need to find the factor of this trinomial.
[tex]x^{2}-6x-16=x^2-8x+2x-16\\\\=x(x-8)+2(x-8)\\\\=(x+2)(x-8)[/tex]
The factors of [tex]x^{2}-6x-16[/tex] is (x-2) and (x-8).
So, the factor of [tex]x^{2}-6x-16[/tex] is (x-8). Hence, the correct option is (B).

A. M<1+ M<2 +M<3 + m<4 = 360
B. The sum of the measures of angles of a triangle is 180°
C. The measure of all right is 90°

how much is 5 quarters and 8 dimes?
Answer:
205
Step-by-step explanation:
Answer: 2.05 dollars
=================================================
Work Shown:
1 quarter = 25 cents
5 quarters = 125 cents .... multiply both sides by 5
1 dime = 10 cents
8 dimes = 80 cents .... multiply both sides by 8
(5 quarters) + (8 dimes) = (125 cents) + (80 cents) = 205 cents
205 cents = 205/100 = 2.05 dollars
-------------------------
Another way to approach the problem is to compute
5*25 + 8*10 = 205
that's the total number of cents

A credit card company charges a 3.5% transfer fee to transfer a balance to a new account. What would the transfer fee be for a balance transfer of $7,500?
Answer:
$262.5
Step-by-step explanation:
We are told that:
A credit card company charges a 3.5% transfer fee to transfer a balance to a new account.
The transfer fee be for a balance transfer of $7,500 is calculated as:
3.5% × $7500
= 3.5/100 × $7500
= $262.5
The transfer fee for a balance transfer of $7500 is $262.5
A cuboid with a volume of 924cm^3 has dimensions 4cm, (x+1)cm and (x+11). Show clearly that x^2+12x-220=0 solve the equation by factorisation, making sure you show the factorisation. Finally, find the dimensions of the cuboid,
Answer:
[tex]x^2+12x-220=0[/tex] -- Proved
[tex]x = 10\ \ \ x = -22[/tex]
Step-by-step explanation:
Given
[tex]Volume = 924cm^3[/tex]
[tex]Dimension: 4cm; (x+1)cm; (x+11)cm[/tex]
Required
Show that [tex]x^2+12x-220=0[/tex]
The volume is calculated as:
[tex]4 * (x + 1) * (x + 11) = 924[/tex]
Open the brackets
[tex](4x + 4) * (x + 11) = 924[/tex]
[tex]4x^2 + 44x + 4x + 44 = 924[/tex]
[tex]4x^2 + 48x+ 44 = 924[/tex]
Collect Like Terms
[tex]4x^2 + 48x+ 44 - 924=0[/tex]
[tex]4x^2 + 48x -880=0[/tex]
Divide through by 4
[tex]\frac{4x^2}{4} + \frac{48x}{4} -\frac{880}{4}=0[/tex]
[tex]x^2+12x-220=0[/tex]
Solving further:
Expand the expression
[tex]x^2 + 22x - 10x - 220 = 0[/tex]
Factorize:
[tex]x(x + 22) - 10(x + 22) = 0[/tex]
[tex](x - 10)(x + 22) = 0[/tex]
Split:
[tex]x - 10 = 0;\ \ \ x + 22 = 0[/tex]
[tex]x = 10\ \ \ x = -22[/tex]

What are the roots of the polynomial equation: 4k - 144 = 0 Show all of your work!
Answer:
k = ±6
Step-by-step explanation:
guess your question is 4k²–144 = 0??
4k² = 144
k² = 36
k²–36 = 0
(k+6)(k–6) = 0
k+6 = 0 | k–6 = 0
k = –6, k = 6.
Alternatively; k = ±6.
Point A has coordinates (6,4) and point B has coordinates (2,7) write AB as column vector. Plz plz plz
Answer:
[tex]\overrightarrow{AB }=\begin{bmatrix}-4\\3 \end{bmatrix}[/tex]
Step-by-step explanation:
Column Vector
Vectors are matrices having only one column or one row. A vector having only one column is called a column vector, and a vector having only one row is called a row vector.
It's required to find the vector AB as a column vector, and we are given the coordinates of A=(6,4) and B=(2,7).
The vector directed from A to B is found by subtracting its corresponding coordinates:
[tex]\overrightarrow{AB }=<2-6,7-4>[/tex]
[tex]\overrightarrow{AB }=<-4,3>[/tex]
Now we express the vector as a one-column matrix as follows:
[tex]\overrightarrow{AB }=\begin{bmatrix}-4\\3 \end{bmatrix}[/tex]
