What is the value of k for which the following equation has one solution?
|14+ 7x| - 15 = k
Answer:
7x-1
Step-by-step explanation:
14 + 7x - 15 = k
7x - 1 = k
Finding x,
14 + 7x - 15 = k
=> 14 + 7x = k + 15
=> 7x = k + 15 - 14
=> x = (k + 1)/7
So, 7 * (k+1)/7 - 1 = k
k + 1 - 1 = k
=> k = k
So the answer is true that 7x - 1

After a 60% reduction, a jacket sold for $20. What was the jackets price before the reduction
Answer:
x-0,6x=20
0,4x=20/:0,4
x=50
Step-by-step explanation:
The original price of the jacket will be $50.
What is the percentage?The Percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that after a 60% reduction, a jacket sold for $20. The original cost of the jacket will be calculated as below:-
Let the unknown number be x. Form the equation and solve for the value of x.
x-0,6x=20
0,4x=20/:0,4
x=50
Therefore, the original price of the jacket will be $50.

What is true about triangle LMN? Check all that apply.
LM ⊥ MN.
The triangle is scalene.
The triangle is equilateral.
The triangle is isosceles.
The triangle is a right triangle.
Answer:
The triangle is isosceles.
Step-by-step explanation:
WHY?:
An Isosceles Triangle will have both 2 equal sides and 2 equal angles.
A Equilateral Triangle will have 3 equal sides and 3 equal angles.
A Scalene angle is when all 3 sides have different lengths.
and
A right triangle will have a 90 degree angle.
In triangle LMN, LM is perpendicular on side MN. So that, the triangle LMN is right angle triangle.
To understand more, check below explanation.
Types of triangle:A triangle whose all three sides has different length known as scalene triangle.
A triangle in which all three sides are equal in length known as equilateral triangle.
A triangle in which two sides are equal are known as isosceles triangle.
A triangle in which one angle is 90 degrees known as right angle triangle.
Since, In traingle LMN, LM is perpendicular on MN. Therefore, LMN is right angle triangle.

What is the solution to the inequality in interval notation? |4x+6|≤14
A: [-2,5] B: (-∞, −2] ∪ [5,∞) C: (-∞,-5] ∪ [2,∞) D: [-5,2]
Answer: x>5
Step-by-step explanation: The Absolute Value term is |4x+6|
For the Negative case, we'll use -(4x+6)
For the Positive case, we'll use (4x+6)
-(4x+6) = 14
Multiply
-4x-6 = 14
Rearrange and Add up
-4x = 20
Divide both sides by 4
-x = 5
Multiply both sides by (-1)
x = -5
Which is the solution for the Negative Case
(4x+6) = 14
Rearrange and Add up
4x = 8
Divide both sides by 4
x = 2
x=-5
x=2
Using the Distance Formula and the Pythagorean Theorem, find the distance, to the nearest tenth, from F (5,5) to G (−3,−1).
Answer:
The answer is 10 unitsStep-by-step explanation:
The distance between two points can be found by using the formula
[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
F (5,5) , G (−3,−1)
The distance between them is
[tex] |FG| = \sqrt{( {5 + 3})^{2} + ({5 + 1})^{2} } \\ = \sqrt{ {8}^{2} + {6}^{2} } \\ = \sqrt{64 + 36} \\ = \sqrt{100} \: \: \: \: \: \: \: \: \\ = 10 \: \: \: \: \: \: \: \: \: \: \: \: \: \: [/tex]
We have the final answer as
10 unitsHope this helps you
Distance formula: d = √(x2-x1)²+(y2-y1)²
= √(x2-x1)²+(y2-y1)²
= √(-3-5)²+(-1-5)²
= √-8²+(-6)²
= √64+36
= √100

be is half of the line so 22 is half of the line
22×22=44
tell me if I'm correct if u can
hope this helps :)
Step-by-step explanation:
Hey there!
M is the midpoint of SB.
Midpoint seperates the line into 2 equal parts.
I.e SM = BM.
So, If BM = 22.
SB = 22+22= 44 [As SM = BM and SB= SM + BM]
Therefore the value of SB is 44.

Can someone help me figure this out? -2(x+8)=6x+8
Answer:
x = -3
Step-by-step explanation:
First, distribute:
-2x - 16 = 6x + 8
Then, switch the numbers to one side, and switch the variables to another:
-2x - 6x = 8 + 16
Then, simplify:
-8x = 24
Finally, divide -8 on both sides:
We got x = -3

Add one term to the polynomial expression 14x^19 – 9x^15 + 11x^4 + 5x^2 + 3 to make it into a 22nd degree polynomial.
Answer:
The new expression is [tex]p' = 5\cdot x^{2}+11\cdot x^{4}-9\cdot x^{15}+14\cdot x^{19}+12\cdot x^{22}[/tex].
Step-by-step explanation:
A polynomial is a sum of algebraic monomials such that:
[tex]p = \Sigma_{i=0}^{n} c_{i}\cdot x^{i}[/tex]
Where [tex]n[/tex] is the degree of the polynomial and [tex]c_{i}[/tex] is the i-th coefficient of the polynomial. A 22nd degree polynomial has [tex]n = 22[/tex], so that given polynomial must added by a monomial with grade 22. Thus:
If [tex]p = 5\cdot x^{2} + 11\cdot x^{4}-9\cdot x^{15}+14\cdot x^{19}[/tex] and [tex]q = 12\cdot x^{22}[/tex], then we have:
[tex]p' = p+q[/tex]
[tex]p' = 5\cdot x^{2}+11\cdot x^{4}-9\cdot x^{15}+14\cdot x^{19}+12\cdot x^{22}[/tex]
The new expression is [tex]p' = 5\cdot x^{2}+11\cdot x^{4}-9\cdot x^{15}+14\cdot x^{19}+12\cdot x^{22}[/tex].
Erin and Aimee are each responsible for mowing half of their back yard. the yard is rectangular with dimensions 75 feet by 90 feet. Erin starts mowing the corner, gradually working her way towards the middle by mowing concentric bands around the outside edges. If the mower cuts a three foot wide path, at what point should Erin and Aimee stop mowing?
Answer:
Erin should stop at three and a half rounds.
Step-by-step explanation:
One complete round will mow 954 square feet, the total area that she has to mow 3375 square feet. If she goes around three and a half times, she should be finished and stop. This was quite hard to figure out, and may very well be incorrect in some way, but I hope this helps.
