Answer: x=-1°
Step-by-step explanation:
m∠LMP=x°+73° m∠PMN=81°+x° m∠LMN=152° x=?
m∠LMP+m∠PMN=m∠LMN
x°+73°+81°+x°=152°
2x°+154°=152°
2x°+154°-154°=152°-154°
2x°=-2°
Divide both parts of the equation by 2:
x°=-1°

7-2x=9x+19
A.x = 11/12
B.x = -12/11
C.x = 1
Answer:
Answer is "B"
Step-by-step explanation:
Rearrange terms: 7-2x=9x+19
-2x+7=9x+19
Subtract 7 from both sides of the equation: -2x+7=9x+19
-2x+7-7=9x+19-7
Simplify: -2x=9x+12
Subtract 9x from both sides: -2x=9x+12
-2x-9x=9x+12-9x
simplifiy: -11x=12
solution: x=-12/11

Jerry drew AJKL and AMNP so that ZK = ZN, LL LP, JK= 6, and
MN = 18. Are AJKL and AMNP similar? If so, identify the similarity postulate
or theorem that applies.
O A. Similar - AA
O B. Cannot be determined
C. Similar - SSS
OD. Similar - SAS
The two considered triangles JKL and MNP are similar by the AA rule of similarity as the two angles that is ∠ K = ∠ N and ∠L = ∠P are there.
It is given that two triangles that are JKL and MNP are considered in which:
∠K = ∠N
∠L = ∠P
JK = 6
MN = 18.
Now, from ΔJKL and ΔMNP, we have
∠K = ∠N (Given in the question)
∠L = ∠P(Given in the question)
Thus, by AA rule of similarity,
ΔJKL is similar to ΔMNP.
Therefore, the two considered triangles JKL and MNP are similar by the AA rule of similarity as the two angles that is ∠ K = ∠ N and ∠L = ∠P are there.

To find:
The coefficient of [tex]x^6[/tex] in the expansion of [tex](3x-2)^9[/tex].
Solution:
We know that, in the expansion of [tex](x+y)^n[/tex],
[tex]T_{r+1}=^nC_rx^{n-r}y^r[/tex] ...(i)
[tex](3x-2)^9[/tex] has only one x and in [tex]x^6[/tex], the power of x is 6. It is possible if
[tex]n-r=6[/tex]
[tex]9-r=6[/tex]
[tex]9-6=r[/tex]
[tex]3=r[/tex]
Putting n=9, r=3, x=3x and y=-2 in (i), we get
[tex]T_{3+1}=^9C_3(3x)^{9-3}(-2)^3[/tex]
[tex]T_{4}=\dfrac{9!}{3!(9-3)!}\times (3x)^{6}(-8)[/tex]
[tex]T_{4}=\dfrac{9\times 8\times 7\times 6!}{3\times 2\times 1\times (9-3)!}\times (729x^{6})(-8)[/tex]
[tex]T_{4}=84\times (729)\times (-8)\times x^{6}[/tex]
[tex]T_{4}=-489888x^6[/tex]
Therefore, the coefficient of [tex]x^6[/tex] in the expansion of [tex](3x-2)^9[/tex] is -489888.

Find the distance between the points (-16, -16) and (8, -16).
Answer:
24 units
Just add the distance that each is from the origin.
(-16, -16) is 16 away from 0, 0
(8, -16) is 8 away from origin
16 + 8 = 24
This only works because these two points` x-axis coordinates match. It doesn`t work with everything.

XZ is the perpendicular bisector of segment WY. Solve for k. Enter a NUMBER only.
Considering that XZ is the perpendicular bisector of segment WY, we have that the value of k is of k = 6.
What is the effect of XZ being the perpendicular bisector of segment WY?It means that XZ divides the segment into two segments of equal length, given by:
WX = XY.
From the lengths given, we can solve for k as follows:
3k + 17 = 7k - 7
4k = 24.
k = 24/4
k = 6.
The value of k is of k = 6.

Seven less than twice a number is 43.
Answer:
x = 25
Step-by-step explanation:
Let's start with the sentence
Seven less than twice a number is 43.
Let's rearrange it to make it easier to convert to an equation
Twice a number subtracted by seven is 43
Now let's convert to an equation
Twice a number: 2x
Subtracted: -
Seven: 7
is: =
43
2x - 7 = 43
Now we can simplify by adding 7 to both sides.
2x = 50
Lastly, let's divide by 2 to isolate the x variable.
x = 25

The selling price of a refrigerator, is $724.50. If the markup is 5% of the dealer's cost, what is the dealer's cost of the refrigerator?
If the markup is 5% of the dealer's cost then the dealer's cost of the refrigerator is $690.
Markup can be calculated using the formula.
Markup= (Selling price - Cost )/Cost
In the given question
The selling Price = $724.50
markup = 5% = 0.05
let the dealer's cost be "x".
Substituting the values in the dealer's formula we get
Markup= (Selling price - Cost )/Cost
0.05=(724.50-x)/x
0.05x=724.50-x
x+0.05x=724.50
Solving further we get
1.05x=724.50
x=724.50/1.05
x=690
Therefore , the dealer's cost of the refrigerator is $690.

if -6 ≤ x ≤ -1
if -1 < x≤2
if 2 < x≤6
the missing functions in the piecewise function are f(x) = - x - 4 for - 6 ≤ x ≤ - 1, f(x) = 4 for 1 < x ≤ 2 and f(x) = - 1 / 2 x - 6 for 2 < x ≤6.
We are given the graph of a piecewise function.
We need to complete the function to represent the graph completely.
We know that, a piecewise function is a function that has different functions for a particular set of values for x.
Here, we can see that:
For the values of x in between - 6 and - 1 that is - 6 ≤ x ≤ - 1, we get the function as:
f(x) = - x - 4
For the values of x in between - 1 and 2 that is - 1 < x ≤ 2, we get the function as:
f(x) = 4
For the values of x in between 2 and 6 that is 2 < x ≤6, we get the function as:
f(x) = - 1 / 2 x - 6
Therefore, we get that, the missing functions in the piecewise function are f(x) = - x - 4 for - 6 ≤ x ≤ - 1, f(x) = 4 for 1 < x ≤ 2 and f(x) = - 1 / 2 x - 6 for 2 < x ≤6.

There is an installation fee to join the Pine River country club as well as monthly dues the total cost of her seven month membership will be $3200 and after one and a half years $3970 find both the intuition feet and the monthly dues
Answer:
Monthly charges = $70
Intuition charges = $2710
Step-by-step explanation:
There is intuition fee and per month fee for joining the Pine River country club.
Total cost for 7 months is $3200
Total cost for one and a half years is $3970
one and a half years means 18 months.
To find:
Intuition fee and monthly dues?
Solution:
Let the intuition fee = [tex]i[/tex]
Let the monthly dues = [tex]m[/tex]
Total cost for 7 months can be represented as
[tex]i+7m = 3200[/tex] ..... (1)
Total cost for 18 months can be represented as
[tex]i+18m = 3970 .... (2)[/tex]
Here, we have 2 equations and 2 variables whose values are to be found.
Let us use elimination method to solve the equations.
Subtracting equation (1) from (2):
[tex]11m = 770\\\Rightarrow m = 70[/tex]
Therefore, the monthly dues are $70.
Using equation (1), we can find the value of [tex]i[/tex].
[tex]i + 70\times 7 = 3200\\\Rightarrow i = 3200 - 490\\\Rightarrow i = \$2710[/tex]
Therefore, intuition charges are $2710.

Which expressions are equivalent to 6 + 12x?
Select each equivalent expression.
Answer:
2 (3 + 6x), 3 (2 + 4x) and 6 (1 + 2x)
Step-by-step explanation:
Given the expression 6 + 12x.
The following functions are equivalent;
Factoring out common number;
For 2;
2(3) + 2(6x)
2 (3 + 6x)
Factoring out 3;
3(2) + 3(4x)
3 (2 + 4x)
Factoring out 6;
6(1) + 6(2x)
6 (1 + 2x)
Hence the possible equivalent expressions are 2 (3 + 6x), 3 (2 + 4x) and 6 (1 + 2x)
find the domain and range of {(x, y) : |x| + y ≥ 2}
Answer:
[tex]\textsf {Domain} : -\infty \: < x < \infty \\\textsf {In interval notation: } (-\infty, \infty)}[/tex]
[tex]\textsf {Range: } f\left(x\right)\le \:2 \\\textsf {In interval notation:} \:(-\infty \:,\:2][/tex]
Step-by-step explanation:
There are no undefined points for the function. So the domain is the set of all x values
The domain of x is (-∞, ∞) so x can be negative or positive. However, |x| is always positive
So if the inequality |x| + y ≥ 2 is to hold good then y has to be less than equal to 2, otherwise the left side drops below 2 and the inequality is not satisfied.
So the range is the set of all values in the interval (-∞, 2)
