Answer:
No solution
Step-by-step explanation:
Solving inequalities is similar to solving equations. First let's distribute the 3 with (k-9)
\(3(k - 9) > 3k + 6\)
\(3k - 27 > 3k + 6\)
(Subtract 3k from both sides)
\( - 27 > 6\)
\( - 33 > 0\)
(Subtract 6 from both sides. You can also add 27 to both sides. You will get the same answer.)
This inequality is invalid. There are no values of k that make the inequality true.

No solution

Find the measure of the arc or central angle indicated. Assume that lines which appear to be diameters are actual diameters
(11) The measure of angle IGJ is 46⁰.
(12) The measure of arc JH is determined as 138⁰.
What is the measure of the arc or central angle indicated?The measure of the arc or central angle indicated is calculated as follows;
(11) The measure of angle IGJ is calculated as follows;
m∠LGK = arc angle LK (interior angle of intersecting secants)
m∠LGK = 48⁰
m∠HGI = m∠LGK = 48⁰ (vertical opposite angles are equal)
m∠IGJ + m∠HGI + m∠JGK = 180⁰ (sum of angles in a straight line)
m∠IGJ + 48⁰ + 86⁰ = 180
m∠IGJ = 180 - 134
m∠IGJ = 46⁰
(12) The measure of arc JH is calculated as follows;
arc JH = arc JI + arc IH
arc JI = arc FG
arc FG = 180 - 137⁰ (sum of angle in a straight line)
arc FG = 43⁰
arc FG = arc JI (vertical opposite angles are equal)
arc JH = arc JI + arc IH
arc JH = 43⁰ + 95⁰
arc JH = 138⁰

Naya is filling up the gas tank in her motorcycle she puts 4.145 gallons of gas in the tank if the gas cost $2.57 per gallon how much did nia spend on gas
If Naya is filling up the gas tank in her motorcycle she puts 4.145 gallons of gas in the tank if the gas cost $2.57 per gallon then she spend $10.65
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given,
The cost of one gallon of gas =$2.57
The quantity of gas she puts in the tank = 4.145 gallons
Apply unitary method
Then, the cost of 4.145 gallons of gas = Cost of one gallon of the gas × Quantity of gas
The cost of 4.145 gallons of gas= 2.57×4.145= $10.65
Hence, If Naya is filling up the gas tank in her motorcycle she puts 4.145 gallons of gas in the tank if the gas cost $2.57 per gallon then she spend $10.65

A rectangular lot is 7 yards shorter than it is wide
and its area is 60 square yards. Find the
dimensions of the lot
Step-by-step explanation:
l = w-6
w-6 * w = 60
w^2 - 6w - 60 = 0
w^2 - 12w + 5w - 60=0
w(w-12)+5(w-12) = 0

Twenty more than one- fifth of a number is 120. Find the number.
welp lol
Answer: x=500
Step-by-step explanation:
Twenty more (+20) of a fifth of a number (.2x) is equal to 120. So, the equation would be .2x+20=120. To isolate x, subtract 20 from each side. So now we have .2x=100. To get rid of the .2 or 1/5, we have to multiply everything by the reciprocal of 1/5, or 5. So, 100(5)=.2x(5), or simplified, x=500. Hope this helps!

Let x represent the number of t shirts that the team needs to sell.
We were told that each T shirt costs $12.5. This means that the cost of x T shirts would be $12.5x
If they need to raise a total of at least $850, it means that the amount that they need to raise must be greater than or equal to $850. Given that they have already sold 40 t-shirts, the amount made from 40 T shirts is 40 * 12.5 = $500.
The inequality representing this situation would be

Give the following non-linear equation: z = x² + 4xy + 6xy² 1.1. Linearize the following equation in the region defined by 8 ≤x≤10,2 ≤y ≤4. (8) 1.2. Find the error if the linearized equation is used to calculate the value of z when x = 8, y = 2.
The linearized equation for the non-linear equation z = x² + 4xy + 6xy² in the region defined by 8 ≤ x ≤ 10, 2 ≤ y ≤ 4 is given by :
z ≈ 244 + 20(x - 8) + 128(y - 2).
When using the linearized equation to calculate the value of z at x = 8, y = 2, the error is 0.
1.1. To linearize the equation in the given region, we need to find the partial derivatives of z with respect to x and y:
∂z/∂x = 2x + 4y
∂z/∂y = 4x + 6xy
At the point (x₀, y₀) = (8, 2), we substitute these values:
∂z/∂x = 2(8) + 4(2) = 16 + 8 = 24
∂z/∂y = 4(8) + 6(8)(2) = 32 + 96 = 128
The linearized equation is given by:
z ≈ z₀ + ∂z/∂x * (x - x₀) + ∂z/∂y * (y - y₀)
Substituting the values, we get:
z ≈ z₀ + 24 * (x - 8) + 128 * (y - 2)
1.2. To find the error when using the linearized equation to calculate the value of z at x = 8, y = 2, we substitute these values:
z ≈ z₀ + 24 * (8 - 8) + 128 * (2 - 2)
= z₀
Therefore, the linearized equation gives the exact value of z at x = 8, y = 2, and the error is 0.

What is the slope of the line containing (-2, 5) and (4, -4)?
Answer:
B. - 3 / 2
Step-by-step explanation:
Let,
( x1, y1 ) = ( - 2, 5 )
So,
x1 = - 2
y1 = 5
( x2, y2 ) = ( 4, - 4 )
So,
x2 = 4
y2 = - 4
Formula : -
Slope = ( y2 - y1 ) / ( x2 - x1 )
Slope = ( - 4 - 5 ) / ( 4 - ( - 2 ) )
= - 9 / ( 4 + 2 )
= - 9 / 6
Slope = - 3 / 2
Answer:
B
Step-by-step explanation:
Calculate the slope m using the slope formula
m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)
with (x₁, y₁ ) = (- 2, 5 ) and (x₂, y₂ ) = (4, - 4 )
m = \(\frac{-4-5}{4-(-2)}\) = \(\frac{-9}{4+2}\) = \(\frac{-9}{6}\) = - \(\frac{3}{2}\) → B

The triangle is an isosceles triangle so remaining side less than 2.
What is an isosceles triangle ??
An isosceles triangle in geometry is one with at least two sides that are of equal length. Both having exactly two sides of equal length and having at least two sides of equal length are acceptable specifications, with the latter version containing the equilateral triangle as an exception. The faces of bipyramids, the golden triangle, the isosceles right triangle, and some Catalan solids are all examples of isosceles triangles.
in this figure, it is an isosceles triangle as two sides of the triangle are equal.
The length of one of the congruent sides is 5
The total length of two congruent sides is 10
The perimeter at the most is 12 (meaning the maximum length of the perimeter is 12)
The third side of the triangle must be 12-10 = 2 at the most

let s=∑n=1[infinity]an be an infinite series such that sn=4−4n2. (a) what are the values of ∑n=110an and ∑n=416an? ∑n=110an=
The expression for the nth term an, for the infinite series s=∑n=1[infinity]an is ∑n=4¹⁶an = 468
We know that the sum of the first n terms of the series is given by sn. Therefore, we can find an expression for the nth term an by taking the difference between successive values of sn:
sn - sn-1 = an
(4-4n²) - (4-4(n-1)²) = an
Simplifying this expression, we get:
an = 8n - 4
Now we can use this expression to find the values of ∑n=1¹⁰an and ∑n=4¹⁶an:
∑n=1¹⁰an = a1 + a2 + ... + a10
= (81 - 4) + (82 - 4) + ... + (8*10 - 4)
= 76
Therefore, ∑n=1¹⁰an = 76.
Similarly,
∑n=4¹⁶an = a4 + a5 + ... + a16
= (84 - 4) + (85 - 4) + ... + (8*16 - 4)
= 468
Therefore, ∑n=4¹⁶an = 468.

Which of the following is a univariate display of quantitative data? histogram mosaic plot bar chart scatterplot
A histogram is a univariate display of quantitative data that organizes data into bins and shows the frequency of observations within each bin.
A histogram is a graphical representation that displays the distribution of quantitative data. It consists of a series of contiguous bars, where each bar represents a specific range or bin of values, and the height of the bar corresponds to the frequency or count of observations falling within that range.
Histograms are commonly used to visualize the shape, central tendency, and spread of a dataset. By examining the heights of the bars, one can determine the frequency of values within each bin and identify patterns such as peaks or clusters. This makes histograms an effective tool for exploring the distribution and characteristics of a single variable in a dataset.

x - 3= -21
This is so confusing:(
Answer:
\(\huge\boxed{x=-18}\)
Step-by-step explanation:
In order to solve this, we are trying to find the value of \(x\). Basically, \(x\) is a placeholder for a number that is unknown. Some number minus 3 is equal to 21.
Our goal is to find \(x\). To do this we want to isolate \(x\) on one side of the equation
\(x-3=-21\)
Let's add 3 to both sides.
\(x-3 + 3 = -21+3\\\\-3 + 3 = 0\\\\x = -21+3\\\\x=-18\)
Hope this helped!
Answer:
x = -18
Step-by-step explanation:
x - 3 = -21
add 3 to both sides
x - 3 + 3 = -21 + 3
x = -18
sidenote: you can add anything to both sides of an equation, and it'll still be true. for example, 2 = 2, if you add 1 to both sides you get 3=3 which is still true.
