The solving linear equation states that the temperature of the oven is 119 after an minute.
What is a linear equation?A linear equation is just an algebraic equation of something like the form y=mx+b that only contains a constant and a first-order (linear) component, where m represents the slope and b is the y-intercept. Sometimes, the aforementioned is referred to as a "linear equation of two variables," where y and x are now the variables.
According to the given data:Given:
y = 40x+79
X = number of minutes using it to bare:
When X = 1

Select all the points of intersection between the graphs of the functions f(x)=(x+5)(x-2)and g(x)=(2x + 1)(x-2)
Select all that apply
a: (-5,0)
b: (-1/2,0)
c: (-2, -12)
d: (2,0)
e: (4, 18)
f: (5, 30)
The point of intersection between the function f(x) and g(x) is x = 4 then, g(x)=18 where option E (4,18) is correct answer.
What is a function?
A function is defined as a relation between a set of inputs having one output each.
We have,
f(x) = ( x + 5 ) ( x - 2 )
g(x) = ( 2x + 1 ) ( x - 2 )
To find the points of intersection between the two functions we must equal the function.
f(x) = g(x)
( x + 5 ) ( x - 2 ) = ( 2x + 1 ) ( x - 2 )
( x - 2 ) gets canceled
x + 5 = 2x + 1
5 - 1 = 2x - x
4 = x
x = 4
This means that at x =4 the function f(x) and g(x) intersect.
we can see that at x = 4 both the functions have the same value.
f(x) = ( x + 5 ) ( x - 2 ) = ( 4 + 5 ) ( 4 - 2 ) = 9 x 2
f(x) = 18
g(x) = ( 2x + 1 ) ( x - 2 ) = ( 2 x 4 + 1 ) ( 4 - 2 ) = ( 8 + 1 ) ( 4 - 2 )
= 9 x 2
g(x) = 18
Thus the point of intersection between the function f(x) and g(x) is x = 4 then, g(x) =18 where option E (4,18) is correct answer.

Let f left parenthesis x right parenthesis equals x cubed minus x squared minus 1 and x subscript 0 equals 1 . To the nearest three decimal places, find x subscript 5 using Newton's method of approximation.
The value of \(x_5\), rounded to the nearest decimal place using Newton's method of approximation is 1.466.
The correct answer is option B.
To find the value of \(x_5\)using Newton's method of approximation, we need to iterate the following formula:
\(x_(_n_+_1_) = x_n - f(x_n) / f'(x_n)\)
where f'(x) represents the derivative of the function f(x). Let's calculate the values step by step.
Given function: f(x) = \(x^3 - x^2 - 1\)
Step 1: Find the derivative of f(x)
f'(x) = \(3x^2 - 2x\)
Step 2: Initialize the starting value
\(x_0\)= 1
Step 3: Calculate \(x_1\)
\(f(x_0) = f(1) = (1^3) - (1^2) - 1 = 1 - 1 - 1 = -1\)
\(f'(x_0) = f'(1) = (3(1^2)) - (2(1)) = 3 - 2 = 1\)
\(x_1 = x_0 - f(x_0) / f'(x_0)\)
= 1 - (-1) / 1
= 2
Step 4: Calculate \(x_2\)
\(f(x_1) = f(2) = (2^3) - (2^2) - 1 = 8 - 4 - 1 = 3\)
\(f'(x_1) = f'(2) = (3(2^2)) - (2(2)) = 12 - 4 = 8\)
\(x_2 = x_1 - f(x_1) / f'(x_1)\)
= 2 - 3 / 8
= 1.625
Step 5: Repeat the process until we reach \(x_5\)
Performing the calculations for \(x_3, x_4, andx_5\), we find:
\(x_3\) ≈ 1.465
\(x_4\) ≈ 1.466
\(x_5\)≈ 1.466
After applying Newton's method of approximation to the function f(x) = \(x^3 - x^2 - 1,\)starting with,\(x_0 = 1,\) we iteratively calculated the values of \(x_1, x_2, x_3, x_4, and x_5\). The final approximation, \(x_5\), is approximately 1.466 when rounded to the nearest decimal place. This aligns with option B as the correct answer.

AB || DC means we know that angle ABD = angle CDB. They are alternate interior angles. This is shown as the red angle markers in the diagram below.
Similarly, AD || BC leads to angle DBC = angle BDA. They are also alternate interior angles and they are marked in green in the diagram below.
So far we have two pairs of congruent angles.
The pair of congruent sides is BD = BD by the reflexive property. Any segment is congruent to itself.
So we can use ASA to prove the triangles congruent. Note the segment BD is between the angles mentioned.

Answer:
Step-by-step explanation:
1. Solve inequality:
||x-5|-4|≤1
Answer:
0 ≤ x ≤ 2 or 8 ≤ x ≤ 10
In interval notation:
[0, 2] ∪ [8,10]
Step-by-step explanation:
||x - 5| - 4| ≤ 1
⇒ -1 ≤ |x-5| - 4 ≤ 1
⇒ -1 +4 ≤ |x - 5| ≤ 1 + 4
⇒ 3 ≤ |x - 5| ≤ 5
Now, if (x - 5) ≥ 0,
We will get
3 ≤ x - 5 ≤ 5
3 + 5 ≤ x ≤ 5 + 5
8 ≤ x ≤ 10
But, if (x-5) ≤ 0
We will get
3 ≤ - (x - 5) ≤ 5
3 ≤ -x + 5 ≤ 5
3 -5 ≤ -x ≤ 5 - 5
-2 ≤ - x ≤ 0
Multiplying by -1 will reverse signs and reverse inequality
(-2)(-1) ≤ (-x)(-1) ≤ 0

L1 and L2 are two straight lines. The origin of the coordinate axes is O. L1 has equation 5x + 10y = 8 L2 is perpendicular to L1 and passes through the point with coordinates (8, 6) L2 crosses the x-axis at the point A. L2 intersects the straight line with equation x = –3 at the point B. Find the area of triangle AOB. Show your working clearly.
Answer:
40 sq units
Step-by-step explanation:
\(5x + 10y = 8\\\Rightarrow y=\dfrac{8-5x}{10}\\\Rightarrow y=-\dfrac{1}{2}x+\dfrac{2}{5}\)
Slope of \(L_2\) is \(m_2\)
\(m_1m_2=-1\\\Rightarrow m_2=-\dfrac{1}{m_1}\\\Rightarrow m_2=-\dfrac{1}{-\dfrac{1}{2}}\\\Rightarrow m_2=2\)
\(L_2\) passes through point \((8,6)\)
\(y-6=2(x-8)\\\Rightarrow y=2x-16+6\\\Rightarrow y=2x-10\)
Point at x axis where \(L_2\) intersects is
\(0=2x-10\\\Rightarrow x=\dfrac{10}{2}\\\Rightarrow x=5\)
Point \(A\) of the triangle will be \((5,0)\)
\(L_2\) intersects line \(x=-3\). The point is
\(y=2\times(-3)-10\\\Rightarrow y=-6-10\\\Rightarrow y=-16\)
The points of the triangle are \(A(5,0), O(0,0), B(-3,-16)\)
Area of triangle is given by
\(A=\dfrac{|A_x(B_y-O_y)+B_x(A_y-O_y)+O_x(A_y-B_y)|}{2}\\\Rightarrow A=\dfrac{|5(-16-0)+-3(0-0)+0(0-(-16))|}{2}\\\Rightarrow A=40\ \text{sq units}\)
The area of the triangle is 40 sq units.

Two forces act on a particle of mass 5 kg which has acceleration of 21 - 3j ms¹².
One of the forces is 8i + j N.
What is the other force?
The other force acting on the mass along with (8i + j)N is (2i - 16j) N.
Two forces are acting on the body and mass of the body is 5 Kg. One force acting is (8i + j) N. The net acceleration of the body is (2i - 3j)m/s².
The other force which is acting on the particle will have two components which should be along i and j.
Let the other force to be (xi +yj) N.
To find x and y, we should analyze the force separately in both the directions,
First analyzing in x direction,
Total force in x direction,
= (8i + xi)N
Total acceleration in x direction,
= 2i m/s²
Mass of body is 5Kg.
Using the formula,
Force = mass × acceleration
(8 + x)i= 5kg × 2i
(8 + x) = 10
x = 2
The x component of the other force is 2Ni.
Now, analyzing in y direction,
Total force in y direction,
= (j + yj)N
Total acceleration in y direction,
= -3j m/s²
Mass of body is 5Kg.
Using the formula,
Force = mass × acceleration
(1 + y)i= 5kg × -3j
(1 + y) = -15
y = -16
So, the y component of the force is -16Nj.
On combining both the components,
The other force F is,

This year, the number of raffle tickets sold for a school's extracurricular activities fundraiser is 848. It is estimated that the number of raffle tickets sold will increase by 5% each year.
The total number of raffle tickets sold at the end of 9 years is approximately 9,818.
To find the total number of raffle tickets sold at the end of 9 years, we need to calculate the number of tickets sold each year and sum them up.
Starting with the initial number of tickets sold, which is 848, we will increase this number by 5% each year for a total of 9 years.
Year 1: 848 + (5% of 848) = 848 + 42.4 = 890.4
Year 2: 890.4 + (5% of 890.4) = 890.4 + 44.52 = 934.92
Year 3: 934.92 + (5% of 934.92) = 934.92 + 46.746 = 981.666
Year 9: Ticket sales at the end of 9 years = Number of tickets sold in Year 8 + (5% of Year 8 sales)
Year 9: Total = 1,399.585 + 69.97925 = 1,469.56425 ≈ 1,469.56
