Step-by-step explanation:
Tom = s
Nancy = r
s=r-2 = Tom=Nancy-2
This means that Tom has $2 less than Nancy as they stayed in the information they gave us. They want us to complete the graph.
Since Tom has $2 less than Nancy all we have to do is apply rule -2 to each number.
4-2=2
8-2=6
12-2=10
Therefore the numbers to add to the graph are 2, 6, and 10.

Answer:
a. 2/3
b. [tex]\sqrt{2}[/tex]
c. 3
d. 5
e. 2
f. Undefined
Step-by-step explanation:
a. [tex]f(x)=\frac{|x-3|}{x+2}[/tex]
To find f(1), plug in 1 where every x is in the equation
[tex]f(1)=\frac{|1-3|}{1+2}=\frac{|-2|}{3}=\frac{2}{3}[/tex]
b. [tex]f(x) = \sqrt{x+1}[/tex]
[tex]f(1) = \sqrt{1+1}=\sqrt{2}[/tex]
c. [tex]f(x) = x^2+5x-3[/tex]
[tex]f(1) = (1)^2+5(1)-3=1+5-3=6-3=3[/tex]
d. [tex]f(x)=\frac{2x+3}{x}[/tex]
[tex]f(1)=\frac{2(1)+3}{1}=\frac{5}{1}=5[/tex]
e. [tex]f(x) = |2x-4|[/tex]
[tex]f(1) = |2(1)-4|=|2-4|=|-2|=2[/tex]
f. [tex]f(x)=\frac{7-2x}{x-1}[/tex]
[tex]f(1)=\frac{7-2(1)}{1-1}=\frac{5}{0}[/tex]
This equation is undefined when x=1 because 0 is the denominator of the fraction.

A The length of a rectangle is 4 m more
than the width. The area of the rectangle
is 45 m2. Find the length and width.
Given :
The length of a rectangle is 4m more than the width.The area of the rectangle is 45m²⠀
To Find :
The length and width of the rectangle.⠀
Solution :
We know that,
[tex]\qquad { \pmb{ \bf{Length \times Width = Area_{(rectangle)}}}}\:[/tex]
So,
Let's assume the length of the rectangle as x and the width will be (x – 4).
⠀
Now, Substituting the given values in the formula :
[tex]\qquad \sf \: { \dashrightarrow x \times (x - 4) = 45 }[/tex]
[tex]\qquad \sf \: { \dashrightarrow {x}^{2} - 4x = 45 }[/tex]
[tex]\qquad \sf \: { \dashrightarrow {x}^{2} - 4x - 45 = 0 }[/tex]
[tex]\qquad \sf \: { \dashrightarrow {x}^{2} - 9x+ 5 x - 45 = 0 }[/tex]
[tex]\qquad \sf \: { \dashrightarrow x(x - 9) + 5(x - 9) = 0 }[/tex]
[tex]\qquad \sf \: { \dashrightarrow (x - 9) (x + 5) = 0 }[/tex]
[tex]\qquad \sf \: { \dashrightarrow x = 9, \: \: x = - 5}[/tex]
⠀
Since, The length can't be negative, so the length will be 9 which is positive.
⠀
[tex]\qquad { \pmb{ \bf{ Length _{(rectangle)} = 9\:m}}}\:[/tex]
[tex]\qquad { \pmb{ \bf{ Width _{(rectangle)} = 9 - 4=5\: m}}}\:[/tex]
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
The length is 9m and the width is 5m.
What is a Rectangle?This is defined as is a quadrilateral with four right angles and the area is calculated as Length × width.
Let's assume length is x and width is (x-4).
We have x × (x-4) = 45m²
x² - 4x = 45
x² - 4x - 45 = 0
x² - 9x + 5x -45 = 0
x(x-9) +5 (x-9)
(x+5)(x-9) = 0
x = -5 or x = 9
x is therefore 9m and the width is (9-4) = 5m

The volume of the right cone below is 30 pi units. Find the value of x.
Answer: X =
HELP QUICK
Answer:
i believe the answer is 2.5
Step-by-step explanation:
The value of x in the given right cone is 10 units.
What is Cone?A cone is a geometrical shape in three dimension formed by a set of lines joined from a point to every points on the base surface which is a circle.
The common point where the lines join is called apex.
The distance from apex to the circular base is called the height of the cone.
The radius of the circular base is also the radius of the cone.
Volume of a Cone is calculated as V = [tex]\frac{1}{3}[/tex] πr²h, where h is the height of the cone and r is the radius of the cone.
We have, Volume of the cone = 30π units³.
From the figure given, diameter of the circular base = 6 units
So, the radius of the cone = 6/2 = 3 units
We have to find the height of the cone.
Substituting these values in the equation for the volume,
30π = [tex]\frac{1}{3}[/tex] π × 3² × h
30 = = [tex]\frac{1}{3}[/tex] × 3² × h
30 = 3h
h = 10
Hence, the height of the cone with radius 3 units and volume 30π units is 10 units.

1x 15 = 15
Answer: Choice C
(3 x 8) x 6 = 3 x (8 x 6)
=================================================
Explanation:
The associative property in general is
(a x b) x c = a x (b x c)
where the x stands for the multiplication symbol.
The a,b,c is in the same order for both sides, but grouped in slightly different ways with the parenthesis.
Plug in a = 3, b = 8, c = 6 to arrive at (3 x 8) x 6 = 3 x (8 x 6)

Answer:
(a) 5 : 8 < 7 : 10
(b) 9/6 = 36/24
Step-by-step explanation:
(a)Perhaps simplest to explain is the use of a common denominator: 40.
[tex]5 : 8 = (5\cdot5):(8\cdot5)=25:40\\\\7:10=(7\cdot4):(10\codt4)=28:40\\\\25:40 < 28:40\quad\leftrightarrow\quad\boxed{5:8 < 7:10}[/tex]
__
Other ways you can do this comparison are ...
Multiply by 8·10 = 80, the product of the denominators:
5·10 = 50 < 7·8 = 56
Convert the fractions to decimal:
5/8 = 0.625 < 7/10 = 0.700
__
(b)Remove a factor of 4 from the second fraction:
[tex]\dfrac{9}{6}\text{ and }\dfrac{36}{24}\quad\leftrightarrow\quad\boxed{\dfrac{9}{6}=\dfrac{9\cdot4}{6\cdot4}}[/tex]
The cost to produce x units of wire is C=30x +500, while the revenue is R = 40x. Find the interval where the product will at least break even.
The break even point is the point where the cost and the revenue are equal
The break even point is at x = 50
How to determine the break even intervalThe functions are given as:
C(x) = 30x + 500 --- cost function
R(x) = 40x ---- revenue function
At the break even, we have:
R(x) = C(x)
So, the equation becomes
40x = 30x + 500
Subtract 30x from both sides
10x = 500
Divide both sides by 10
x = 50
Hence, the break even point is at x = 50

Answer:
3⁻ⁿ⁺²
Step-by-step explanation:
we need to make both bases the same
9 can be written as 3²
[tex] \frac{3 {}^{n} }{3 {}^{2(n - 1)} } [/tex]
multiply 2(n-1) = 2n - 2
[tex] \frac{3 {}^{n} }{3 {}^{2n - 2} } [/tex]
I'll rewrite as 3ⁿ ÷ 3²ⁿ⁻²
subtract the exponents when dividing numbers with the same base
n - (2n-2) or n - 1(2n-2) imagine the 1 is there
remember that the whole of (2n-2) is being multiplied by -1, so expanding
n - 2n + 2 = -n + 2
final answer: 3⁻ⁿ⁺²
