The length of a rectangle is 6 centimeters greater than the width. The area of the
rectangle is 112 square centimeters. Find the length and the width.
Answer:
Step-by-step explanation:
Width = w
Length = w + 6
Area = 112 sq. cm
length * width = 112
(w +6 ) *w = 112
w² +6w -112 = 0
Sum = 6
Product = -112
Factors = 14 , -8 {14 - 8 = 6 , (-8)*14 = -112}
w² + 14w - 8w -112 = 0
w(w + 14) - 8(w + 14)=0
(w +14)(w -8) = 0 {Ignore w + 18 as measurement won't be negative}
w - 8 = 0
w = 8 ft
Length = 8 + 6 = 14 ft

Is value of the 2 in the tenths place the same value of the 2 in the ones place?
Answer:
No.
Step-by-step explanation:
If two were in the ones place, which would look like this: 2, then you would have two of an object. So two dogs, cats, ect.
If two were in the tenths place, which would look like this: .2, then you have two thenths of an object. Not one complete object, just that amount of it.
You would not want two tenths of a sock for a present, you would want two socks.

let's start from bottom left point
we have to calculate position from P to that point as below
it is 2 units up and 11 units left
so as scale factor is 1/2
we have to shift that point to 1 unit up and 5.5 units left
pink point corresponding to it is denoted below
we have to do the same process for all the five points to cover the total figure

Using it's concept, it is found that the mean income in Sambala is of $87,571.43.
The mean of a data-set is the sum of all observations in the data-set divided by the number of observations.
In this problem, there are 7 observations: 35000, 46000, 68000, 300000, 57000, 41000 and 66000.

Jack Is 2 times as old as lacy. 8 years from now the sum of their ages will be 61. How old are they now?
Answer:
Jack = 30
Lacy = 15
Step-by-step explanation:
Let the age of Lacy be " x ".
Jack Is 2 times as old as lacy,
Age of Jack = 2 * Age of Lacy
Therefore,
Age of Jack = 2x.
8 years from now,
the age of Jack = 2x + 8
the age of Lacy = x + 8
8 years from now the sum of their ages will be 61,
2x + 8 + x + 8 = 61
2x + x + 8 + 8 = 61
3x + 16 = 61
3x = 61 - 16
3x = 45
x = 45 / 3
x = 15
The age of Jack
= 2x
= 2 * 15
= 30 years old.
The age of Lacy
= x
= 15 years old.
Hence,
Now,
the age of Jack is 30 years old.
the age of Lacy is 15 years old.

Answer:
w > -0.4
Step-by-step explanation:
Given the inequality expression, w – 0.7 > -1.1:
First, we must isolate the variable, w, by adding 0.7 to both sides of the inequality statement:
w – 0.7 + 0.7 > –1.1 + 0.7
w > -0.4
Therefore, the correct ray is the empty circle with its ray pointing towards the right (Option 4). This implies that -0.4 is not included as an endpoint in the inequality.
Attached is a screenshot of the number line where it shows where the empty circle is located, along with the direction of the arrow.

8. Math on the Spot Write an equation in slope-intercept form for the line that passes
through (5, -6) and is parallel to the line described by y = -x+ 3.
Answer: y=-x-1
Step-by-step explanation:
To find the answer, 5 and -6 have to be substituted in the place of x in the equation y = -x + b(The slope has to be the same because the line is parallel). -6 = -5 + b, b = -1. This means that the equation is y = -x - 1.
how do you find the zeros of an equation
Answer:
Step-by-step explanation:
In general, given the function, f(x), its zeros can be found by setting the function to zero. The values of x that represent the set equation are the zeroes of the function. To find the zeros of a function, find the values of x where f(x) = 0.
Answer:
Use the rational root theorem to list all possible rational zeroes of the polynomial P(x) P ( x) .
Evaluate the polynomial at the numbers from the first step until we find a zero. ...
Repeat the process using Q(x) Q ( x) this time instead of P(x) P ( x) . This repeating will continue until we reach a second degree polynomial.

Write the first five terms of the arithmetic sequence. a1 = 9; d = -2
Answer:
nth term = 1 1/2n -1
Step-by-step explanation:
The arithmetic sequence formula is:
a n = a 1 + ( n – 1 ) d
Where: a n
is the nth term in the sequence
a 1
is the first term in the sequence
n
is the term you are solving for
d
is the common difference for any pair of consecutive numbers in the sequence.
First Term or
n = 1 :
This is given in the problem.
a 1 = 9
Second Term or
n = 2 :
Substitute
2 for n
in the formula and substitute the values from the problem giving:
a 2 = 9 + ( ( 2 – 1 ) × -2 )
a 2 = 9 + ( 1 × -2 )
a 2 = 9 +-2
a 2 = 7
Fifth Term or n = 5 :
Substitute in the formula and substitute the values from the problem giving:
a 5 = 9+ ( ( 5– 1 ) × -2 )
a 5 = 9 + ( 4 × -2 )
a 2 = 9 + -8
a 2 = 1
Using this same process you should be able to determiner the
Third Term or n = 3
: and Fourth Term or n = 4 :

In a box there are 6 orange balls, 4 green balls and "x" blue balls. If the probability of drawing a blue ball is 1/3, what is the probability of drawing two blue balls?
Step-by-step explanation:
I assume it is meant to draw 2 blue balls in a row out of the full pool of balls (no other draws happen before or during this process).
tricky, your teacher.
I think the temptation is to simply say 1/3×1/3 = 1/9.
but is it ?
the probabilty to draw one blue ball out of the complete system (no ball missing) is
x / (6+4+x) = 1/3
x = (6+4+x)/3
3x = 6 + 4 + x = 10 + x
2x = 10
x = 5
so, we have a system of 6 orange, 4 green and 5 blue balls (15 all together) .
the probability at our first pull to draw a blue ball is the indicated 5/15 = 1/3.
but now, for the second ball, we have only 6 orange, 4 green and 4 blue balls in the pool (14 altogether).
and so the probability to draw a blue ball out of this is
4/14 = 2/7.
therefore, the probability to draw 2 blue balls is now the combination
1/3 × 2/7 = 2/21
aha ! so, it is a little bit less than the originally suspected probability of 1/9.

Answer Choices Below!:
Answer:
A
Step-by-step explanation:
If f(x)=1–2x + k and f(f(k)) = 13, determine the value of f(-1).
By definition of f(x),
f(k) = 1 - 2k + k = 1 - k
Then
f(f(k)) = f(1 - k) = 1 - 2 (1 - k) + k = 3k - 1 = 13
Solve for k :
3k - 1 = 13
3k = 14
k = 14/3
Find f(-1) :
f(-1) = 1 - 2 (-1) + 14/3 = 1 + 2 + 14/3 = 23/3

Use the graph shown to find the following.
(a) The domain and range of the function
(b) The intercepts, if any
(c) Horizontal asymptotes, if any
(d) Vertical asymptotes, if any
(e) Oblique asymptotes, if any
(a) The domain of the function is (-∞; 0) U (0; +∞) and the range is (-∞; +∞).
(b) There are 2 x-intercepts: (-2, 0) and (2, 0). There is no y-intercept.
(c) This function does not have horizontal asymptotes.
(d) The vertical asymptote is x = 0.
(e) The oblique asymptote is y = -3x.
We want to find different elements of the function given in the graph.
(a) The domain and range of the functionThe domain of a function is the complete set of possible values of the independent variable. The domain of this function is (-∞; 0) U (0; +∞).The range of a function is the complete set of all possible resulting values of the dependent value. The range of this function is (-∞; +∞).(b) The interceptsThe intercept is a point where the graph of a function intersects the axis. There are 2 x-intercepts: (-2, 0) and (2, 0). There is no y-intercept.
(c) Horizontal asymptotesHorizontal asymptotes are horizontal lines that the graph of the function approaches as x tends to +∞ or −∞. This function does not have horizontal asymptotes.
(d) Vertical asymptotesVertical asymptotes are invisible vertical lines that certain functions approach, yet do not cross, when the function is graphed. The vertical asymptote is x = 0.
(e) Oblique asymptotesAn oblique asymptote is a slanted line that the function approaches as x approaches ∞ or -∞.
We have 2 points for this asymptote: (0, 0) and (2, -6). We can find its expression using the two-point form of a line.
y - y₁ = (y₂-y₁/x₂-x₁) (x - x₁)
y - 0 = (-6-0/2-0) (x - 0)
y = -3x
(a) The domain of the function is (-∞; 0) U (0; +∞) and the range is (-∞; +∞).
(b) There are 2 x-intercepts: (-2, 0) and (2, 0). There is no y-intercept.
(c) This function does not have horizontal asymptotes.
(d) The vertical asymptote is x = 0.
(e) The oblique asymptote is y = -3x.
