Which inequality describes the graph?
The graph is a linear inequality, and the inequality that describes the graph is y < 2x - 1
How to determine the inequality?From the graph, we have the following features:
y-intercept, b = -1It passes through the points (0,-1) and (1,1)The line is a dotted line and the lower region are shaded; so, we make use of the < inequalityNext, we calculate the slope using:
[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]
So, we have:
[tex]m = \frac{1 + 1}{1 - 0}[/tex]
m = 2
The inequality is then calculated using:
y < mx + b
This gives
y < 2x - 1
Hence, the inequality that describes the graph is y < 2x - 1

Find the standard form of the equation of the parabola with the given characteristic(s) and vertex at the origin
The standard form of the equation of the parabola with the given characteristic(s) and vertex at the origin and directrix is y² = 16x.
What is the parabola?It is the locus of a point that moves so that it is always the same distance from a non-movable point and a given line. The non-movable point is called focus and the non-movable line is called the directrix.
Given that the parabola's vertex is located at the origin and that the directrix is at x = -4, the focus is at (4,0).
Then the equation can be written as
[tex]\rm \sqrt{(x-4)^2 +(y-0)^2} = \sqrt{(x+4)^2 + (y-y)^2}\\\\\sqrt{(x-4)^2 +(y-0)^2} = \sqrt{(x+4)^2}[/tex]
On squaring both sides, we have
[tex]\begin{aligned} (x-4)^2 +(y-0)^2 &= (x+4)^2 \\\\x^2 + 16 - 8x +y^2 &= x^2 + 16 + 8x\\\\y^2 &= 16x \end{aligned}[/tex]

What is the sum of the numbers in the series below? 15 11 7 . . . (–129)
Using Gauss's method, the sum of the numbers in the given series [ 15 11 7 . . . . ( –129 ) ] is -2664.
What is an arithmetic sequence?An arithmetic sequence is simply a sequence of numbers in which the difference between the consecutive terms is constant.
From Gauss's method nth term is an arithmetic sequence is expressed as;
n = (( first term - last term )/d) + 1
d is the common difference between terms.
Given the series in the question;
15 11 7 . . . (–129)
d = 15 - 11 = 4
Next, we find n
n = (( first term - last term )/d) + 1
n = (( 15 - (-129))/4) + 1
n = ( 144/4 ) + 1
n = 36 + 1
n = 37
Now, using the common difference between terms the sun will be;
S = 15 + 11 + 7 . . . -125 -129
Also
S = -129 -125 . . . + 7 + 11 + 15
We add
2S = -114, 114, 114 . . . . n
Hence, the sum will be;
2S = ( -114 ) × n
2S = ( -114 ) × 37
2S = -5328
S = -5328 / 2
S = -2664
Therefore, using Gauss's method, the sum of the numbers in the series [ 15 11 7 . . . (–129) ] is -2664.

Question attached and investigates relationship between zeroes and tangents of cubic function
The tangent lines of the cubic function f(x) = x(x - 2)(x - 6) at the zeros 0, 2 and 6 are y = 12x, y = -8x + 16 and y = 24x - 144
Part A: The tangent lines of f(x) = x(x - 2)(x - 6)The cubic function is given as:
f(x) = x(x - 2)(x - 6)
Expand
f(x) = x³ - 8x² + 12x
Differentiate the function
m = 3x² - 16x + 12
At the point x = 0, we have:
m = 3(0)² - 16(0) + 12
m = 12
Also, we have:
f(0) = 0
A linear equation is represented as:
y = m(x - x₁) + y₁
So, we have:
y = 12(x - 0) + 0
y = 12x
At the point x = 2, we have:
m = 3(2)² - 16(2) + 12
m = -8
Also, we have:
f(2) = 0
A linear equation is represented as:
y = m(x - x₁) + y₁
So, we have:
y = -8(x - 2) + 0
y = -8x + 16
At the point x = 6, we have:
m = 3(6)² - 16(6) + 12
m = 24
Also, we have:
f(6) = 0
A linear equation is represented as:
y = m(x - x₁) + y₁
So, we have:
y = 24(x - 6) + 0
y = 24x - 144
The above means that the tangent lines are:
y = 12x, y = -8x + 16 and y = 24x - 144
From the attached graph, we can see that the tangent lines at the zero values x = 0 and x = 2 intersect the graph of f(x) at the zero value x = 6
Part B: The tangent lines of f(x) = (x - a)(x - b)(x - c)The equation is given as:
f(x) = (x - a)(x - b)(x - c)
To prove the statement using a computer algebra system, simply follow the next steps:
Set values for a, b and cInclude the following vertices in the plane: (a,f(a)), (b,f(b)) and (c,f(c))Differentiate f(x) i.e g(x) = f'(x)Include the following vertices in the plane: (a,g(a)), (b,g(b)) and (c,g(c))Lastly, plot the following equations: y = g(a)(x - a) + f(a), y = g(b)(x - b) + f(b) and y = g(c)(x - c) + f(c)See attachment (2) for proof

Two consecutive integers have a sum of 195. Find the integeres
Hey ! there
Answer:
First Integer is 97Second Integer is 98Step-by-step explanation:
The question says that two consecutive Integer have a sum of 195 . And we are asked to find the integers.
For finding integers we are assuming them . So ,
Let the first integer be x .Let the second integer be x + 1 ( This is because in question it's given that they are consecutive integers )Solution : -
According to question ,
First Integer + Second Integer = 195So ,
[tex] \dashrightarrow \qquad \: x + x + 1 = 195[/tex]
Step 1 : Adding like terms ( x and x ) on left side :
[tex] \dashrightarrow \qquad \: 2x + 1 = 195[/tex]
Step 2 : Subtracting 1 on both sides :
[tex] \dashrightarrow \qquad \: 2x + \cancel{1} - \cancel{1} = 195 - 1[/tex]
Simplifying it ,
[tex] \dashrightarrow \qquad \: 2x = 194[/tex]
Step 3 : Dividing with 2 on both sides :
[tex] \dashrightarrow \qquad \: \dfrac{ \cancel{2}x}{ \cancel{ 2}} = \cancel{\dfrac{194}{2} }[/tex]
On further calculations , We get :
[tex] \dashrightarrow \qquad \: \purple{\underline{\boxed{\frak{ x = 97}}}} \quad \: \bigstar[/tex]
We know that ,
x = first number✰ Therefore , first number is 97 .
x + 1 = second number97 + 1 98✰ Therefore , second number is 98.
Verifying : -
Now , we are verifying our answer by substituting value of first and second number and equating it with 195 . So ,
97 + 98 = 195195 = 195L.H.S = R.H.SHence , Verified .Therefore , our solution is correct .

Two consecutive integers have a sum of 195. Find the integers
[tex]\blue{\textsf{\textbf{\underline{\underline{Answer:-}}}}[/tex]
The integers are 97 and 98.
[tex]\blue{\textsf{\textbf{\underline{\underline{How to Solve:-}}}}[/tex]
If integers are [tex]\textbf{consecutive,}[/tex] they stand right next to each other.
Example:- 7 and 8. 7 and 8 are consecutive integers because they stand right next to each other.
Now, let the integer be n.
The integer next to n is 1 greater than n, or n+1.
So we set up the following equation:-
[tex]\bigstar{\fbox{n+n+1=195}[/tex]
[tex]\textsf{\underline}}[/tex]Add the n's:-
[tex]\Longrightarrow[/tex] [tex]\sf{2n+1=195}[/tex]
Subtract 1 on both sides:
[tex]\sf{2n=195-1}[/tex]
[tex]\sf{2n=194}[/tex]
Divide by 2 on both sides:-
[tex]\bigstar{\fbox{n=97}[/tex]
Now that we've found the first integer, finding the second integer is easy, because we can subtract the first integer from the sum of both integers:-
195-97=98
So the second integer is 98.
Quick Check:-
97 and 98 are consecutiveThey add up to 195:-97+98=195[tex]\textbf{195=195}[/tex]Since the LHS (left-hand side) equals the RHS (right-hand side), the integers are indeed 97 and 98.Good luck.

2(50+B)=12050+B=60B=10Area
50(10)500ft²Surprisingly assumption at first turned right
Garden A has highest area not Garden B
Answer:
Garden A
Step-by-step explanation:
Formula
Perimeter of a rectangle = 2(w + l)Area of a rectangle = w × l(where w is the width and l is the length)
Garden AGiven:
Perimeter = 120 ftOne side length = 25 ftUsing the formula for the perimeter to calculate the missing side length:
Perimeter = 2(w + l)
⇒ 120 = 2(25 + l)
⇒ 120 = 50 + 2l
⇒ 2l = 70
⇒ l = 35 ft
Therefore, the dimensions of Garden A are:
width = 25 ftlength = 35ftArea = w × l
⇒ Area of Garden A = 25 × 35
= 875 ft²
Garden BGiven:
Perimeter = 120 ftOne side length = 50 ftUsing the formula for the perimeter to calculate the missing side length:
Perimeter = 2(w + l)
⇒ 120 = 2(w + 50)
⇒ 120 = 2w + 100
⇒ 2w = 20
⇒ w = 10 ft
Therefore, the dimensions of Garden B are:
width = 10 ftlength = 50 ftArea = w × l
⇒ Area of Garden B = 10 × 50
= 500 ft²
ConclusionAs 875 > 500, Garden A has the largest area.

State the equation of a line perpendicular to y = -3 going through (-5, -3).
Answer:
x=-5
Step-by-step explanation:
Answer:
Equation of the perpendicular line is x = -5
Step-by-step explanation:
The equation of the given line is y =-3
This means that the given line is parallel to the x axis. Imagine a horizontal line and for all values of x, the y value is constant -3. So the line perpendicular to this line would be one that is parallel to the Y axis. Imagine a vertical line. This line would have the same x value for all values of Y. Equation would be of the form
x = constant.
It is given that the line passes through (-5, -3), from which we get that constant value as -5.
Equation of the perpendicular line is x = -5
