Answer:
(7x+3)(-x-3)
Step-by-step explanation:
-7x²-24x-9 would be the same thing as (7x+3)(-x-3) because 7x*-x=-7x², +3*-3=-9, and 7x*-3 - 3x = -24x

What is the fourth term of an arithmetic sequence whose first term is 23 and whose seventh term is 5?
A) 78
B) 32
C) 14
(Explain your work)
We have that the fourth term of an arithmetic sequence is
a_4=14
Option C
From the question we are told
What is the fourth term of an arithmetic sequence whose first term is 23 and whose seventh term is 5?
A) 78
B) 32
C) 14
(Explain your work)
Generally the equation for the arithmetic sequence is mathematically given as
[tex]a_4=a_1+(n-1)d[/tex]
Therefore
For seventh term
[tex]5=23+(6)d\\\\d=5-23/(6)\\\\d=-3[/tex]
Therefore
For Fourth term
[tex]a_4=23+(3*(-3))[/tex]
a_4=14

Sandra transforms a line segment such that the new image is longer than the original line segment. What type of transformation must the line segment have undergone?
A. dilation
B reflection
C rotation
E translation
The type of transformation must the line segment have undergone if Sandra transforms a line segment such that the new image is longer than the original line segment, is dilation, so option A is correct.
What is dilation?The process of dilation entails scaling or changing a thing. It is a transformation that uses the specified scale factor to make the objects smaller or larger.
Given:
Sandra transforms a line segment such that the new image is longer than the original line segment,
The above transformation is an example of dilation, as in dilation the image can be transformed into a large image or a small image,
Thus, the given transformation is an example of dilation.

Evaluate.
(jk−1) ÷j when j=−4 and k=−0.8
Enter your answer as a decimal in the box.
Step-by-step explanation:
(jk−1) ÷j
[(-4)(-0.8) -1] ÷ (-4)
=[ 3.2 -1] ÷ (-4)
=2.2 ÷ (-4)
= -0.55
The solution of the expression "[tex]\frac{jk-1}{j}[/tex]" is "-0.55".
The given values are:
j = -4k = -0.8→ [tex]\frac{jk-1}{j}[/tex]
By putting the value of "j" and "k" in the given expression, we get
→ [tex]\frac{(-4)(-0.8)-1}{-4}[/tex]
By solving the brackets, we get
→ [tex]\frac{3.2-1}{-4}[/tex]
→ [tex]\frac{2.2}{-4}[/tex]
→ [tex]-0.55[/tex]
Thus the above response is correct.

of pairs of shoes ordered. Which of the following equations models this
proportional relationship? *
Answer:
9s = 378t
is the same as (9 x 42) etc...
Step-by-step explanation:
I don't have the choice of answers of what is being said as proportional but an example is here below of what numbers are multiples of 42 and therefore found its proportion this way.
10s = 420t (10 x 42)
9s = 378t (9 x 42) etc...

find csc θ and sec θ if cot θ= 3/2 and cos θ>0
Since both cot(θ) and cos(θ) are positive, it follows that sin(θ) is also positive:
cot(θ) = cos(θ)/sin(θ) > 0 ===> sin(θ) > 0
Recall the Pythagorean identity:
sin²(θ) + cos²(θ) = 1
Multiplying both sides by 1/sin²(θ) yields another form of the identity,
sin²(θ)/sin²(θ) + cos²(θ)/sin²(θ) = 1/sin²(θ)
1 + cot²(θ) = csc²(θ)
so that
csc(θ) = + √(1 + cot²(θ))
csc(θ) = √(1 + (3/2)²)
csc(θ) = √13/2
By definition of cosecant, we have
csc(θ) = 1/sin(θ)
so that
sin(θ) = 2/√13
Then using the Pythagorean identity once more, we have
cos(θ) = + √(1 - sin²(θ))
cos(θ) = √(1 - (2/√13)²)
cos(θ) = 3/√13
so that, by definition of secant,
sec(θ) = 1/cos(θ)
sec(θ) = √13/3

The arithmetic mean of ten numbers is -10. If the sum of six of the numbers is 100, what is the arithmetic mean of the other 4?
Answer:
56
Step-by-step explanation:
Arithmetic mean is simply the sum of the all the number present divide by the total number.
From the question, we obtained the following information:
The arithmetic mean = 5.6
Total number present = 10
Sum of the numbers =?
Arithmetic mean = sum of the numbers / total number
Sum of the numbers = arithmetic mean x total number
Sum of the numbers = 5.6 x 10 = 56
The sum of the other four numbers is equivalent to -200.
What is a mathematical function, equation and expression? function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is that the arithmetic mean of ten numbers is -10. The sum of six of the numbers is 100.
We can write -
{a + b + c + d + e + f + g + h + i + j}/10= - 10
{a + b + c + d + e + f + g + h + i + j} = - 10 x 10
{a + b + c + d + e + f + g + h + i + j} = - 100 .... Eq{1}
and
{a + b + c + d + e + f} = 100 .... Eq{2}
We can write Eq{1} as -
{a + b + c + d + e + f} + {g + h + i + j} = - 100
100 + {g + h + i + j} = - 100
{g + h + i + j} = - 100 - 100
{g + h + i + j} = - 200
Therefore, the sum of the other four numbers is equivalent to -200.

What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
f(x) = √x
f(x) is a parent function.
a parent function is the core representation of a function type without manipulations such as translation and dilation.
We have to find the function h(x) which is obtained by transforming the function f(x)
From the given graph, the function f(x) is moved up about 2 units and the shifted left of 5 units
h(x) =√x+2 - 5
Hence, the function h(x) is a transformation of the square root parent function, f(x)= √x then the function h(x) is√x+2 - 5
