Step-by-step explanation:
Step 1: Define Equation
-2x = 34
Step 2: Solve for x
Divide -2 on both sides: x = -17Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: -2(-17) = 34Multiply: 34 = 34Here we see that 34 does indeed equal 34.
∴ x = -17 is the solution of the equation.

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.

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.

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)

Given:
[tex](3x-2)^9[/tex]
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.

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.
