K/3+4-5k=-2k what is the answer???
Answer:
Solve for k by simplifying both sides of the equation, then isolating the variable.
Exact Form: k = 3/2
Decimal Form: k = 1.5
Mixed Number Form: k = 1 1/2
Hope this helps!
Answer:
k = [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Given
[tex]\frac{k}{3}[/tex] + 4 - 5k = - 2k
Multiply through by 3 to clear the fraction
k + 12 - 15k = - 6k
- 14k + 12 = - 6k ( add 14k to both sides )
12 = 8k ( divide both sides by 8 )
k = [tex]\frac{12}{8}[/tex] = [tex]\frac{3}{2}[/tex]

If a,b and c are the sides of a triangle where a = 12, b = 5 and c = 13 is this a right triangle ?
Answer:
yes
Step-by-step explanation:
To determine if the sides form a right triangle.
If the square of the longest side is equal to the sum of the squares on the other 2 sides then triangle is right.
longest side is c = 13
13² = 169
a² + b² = 12² + 5² = 144 + 25 = 169
Since c² = a² + b² = 169
Then the sides form a right triangle

y=-x^3+ 4x^2 – 3 ; [0, 4]
Answer:
0 and 8/3
Step-by-step explanation:
y is continuous on [0,4]
It also also differentiable on (0,4)
Plugging in 0 and 4, we get -3 both times so y(0) = y(4).
Therefore there is at least one value c between 0 and 4 inclusive where y'(c) = 0
y' = -3x^2 + 8x
Set that to 0:
-3x^2 + 8x = 0
x(-3x+8) = 0
x = 0 or 8/3
And both values work.

Use the graph below for this question
What is the average rate of change from x = 0 to x = 2?
-4
-8
1
5
Answer:
The average rate will be: -4
Hence, option A is correct.
Step-by-step explanation:
Given the interval
0 ≤ x ≤ 2
From the graph, it is clear that:
at x₁ = 0, f(x₁) = 3
at x₂ = 2, f(x₂) = -5
Using the formula to determine the average rate of change:
Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]
= [-5 - 3] / [2-0]
= -8 / 2
= - 4
Therefore, the average rate will be: -4
Hence, option A is correct.

A wire is first bent into the shape of a square. Each side of the square is 9cm long. Then the wire is unbent and reshaped into a rectangle. If the length of the rectangle is 13cm, what is its width
Answer:
5 cm
Step-by-step explanation:
the perimeter of a square with sides of 9 cm is 36 cm so the rectangle must have the same perimeter
if the length of the rectangle is 13cm, its opposite side is also 13cm
add 13 + 13 to get 26
let 'n' = width of rectangle
perimeter = 26 + n + n
36 = 26 + 2n
2n = 10
n = 5
If the length of the rectangle is 13 cm then the width of the rectangle will be equal to 5 cm.
What is the perimeter?A shape's perimeter is the whole distance encircling it. It is the perimeter or length of the contour of any two-dimensional geometric body. The circumference of several figures could be compared based on the measurements.
As per the information given in the question,
Length of the side of the square = 8 cm
Then, use the formula of the perimeter of the square = 4 × side
= 4 × 9 = 36 cm
The length of the rectangle = 13 cm
Use the formula of the perimeter of the rectangle,
P = 2(l + w)
36 = 2(13 + w)
36 -26 = 2w
w = 10/2
w = 5 cm

[tex]\boxed{\pink{\tt\longmapsto The \ nth \ term \ of \ the \ sequence\ is \ given \ by \frac{1}{n}}} [/tex]
Step-by-step explanation:A sequence is given to us is , and we need to find expression for nth term of the sequence. The given sequence is ,
[tex]\boxed{\boxed{\blue{\qquad\bf 1 , \dfrac{1}{2},\dfrac{1}{3},\dfrac{1}{4},\dfrac{1}{5},\dfrac{1}{6}}}}[/tex]
When we flip the numbers , we can clearly see that the number are in Harmonic Progression.
That is when we flip the numbers they are found to be in Arithmetic Progression .
And nth term of an Harmonic Progression is :-
[tex]\boxed{\purple{\bf T_{(Harmonic \ Progression)} = \dfrac{1}{a+(n-1)d}}} [/tex]
Hence here
Common difference = 1First term = 1 .Substituting the respective values,
[tex]\bf\implies T_{n}= \dfrac{1}{a+(n-1)d} \\\\\bf\implies T_{n} = \dfrac{1}{1+(n-1)1}\\\\\bf\implies T_n = \dfrac{1}{1+n-1}\\\\\bf\implies\boxed{\red{\bf T_{n}=\dfrac{1}{n}}}[/tex]
