6x-(2x-9)=-31 whats x?
Answer: [tex]x = -10[/tex]
Step-by-step explanation:
Hey there! I hope these steps will help you accomplish this problem :)
Step 1: Remove the parentheses.
[tex]6x - 2x + 9 = -31[/tex]
Step 2: Simplify.
[tex]6x - 2x + 9[/tex] to [tex]4x + 9[/tex].
[tex]4x + 9 = -31[/tex]
Step 3: Subtract 9 from both of the sides.
[tex]4x = -31 - 9[/tex]
Step 4: Simplify.
[tex]-31 - 9[/tex] to [tex]-40[/tex].
[tex]4x = -40[/tex]
Step 5: Divide both of the sides by 4.
[tex]x = -\frac{40}{4}[/tex]
Step 6: Simplify.
[tex]\frac{40}{4}[/tex] to [tex]10[/tex].
[tex]x = -10[/tex]

Step-by-step explanation:
Here you go mate
step 1
6x-(2x-9)=-31 equation
step 2
6x-(2x-9)=-31 simplify
6x+-1(2x-9)=-31
step 3
6x+(-1)(2x-9)=-31 distribute
6x+-1(2x)+(-1)(-9)=-31
6x+-2x+9=-31
step 4
(6x+-2x)+(9)=-31 combine the terms that are alike
4x+9=-31
step 5
4x+9(-9)=−31(-9) subtract-9
4x=-40
step 6
4x/4=-40/4 divide by 4 because 4 is a number that can make the division easier

A band earned $550.00 for playing at a concert. Their manager takes 15% of the money earned for each show and the band is donating 20% of the money earned to charity. How much money is left for the band to split?
Answer:
The amount of the money earned left for the band to split is $357.5
Step-by-step explanation:
The amount the band earned for playing at the concert = $550.00
The percentage of the money earned taken by the manager = 15%
The percentage of the money earned the band is donating to charity = 20%
The amount of the money earned the manager takes = 15/100 × 550 = 82.5
∴ The amount of the money earned the manager takes = $82.5
The amount of the money earned that is donated to charity = 20/100 × 550 = 110
∴ The amount of the money earned that is donated to charity = $110
The amount of the money earned left for the band to split = $550 - $82.5 - $110 = $357.5.

12.) a

13.) e
14.) d
15.) b
PAGE 4 (SCREENSHOT)
Step-by-step explanation:
PAGE 1
16.) C b/c if you draw a line through it you have line of symmetry and a regular hexagon has rotational symmetry.
PAGE 2
11.) P(6, 2) ----(6*3, 2*3) -----> P'(18, 6)
So e is the answer
12.) The compound transformation should read
Dilation with center at origin and scale factor of 1/2
Reflection across the x-axis
Reflection across the x-axis rule is (x, y) -->(x, -y)
a is the answer b/c A(-1, -2) --> A'(-1/2, -1) --> (-1/2, 1)
PAGE 3
13.) The scale of the dilation is 1/4 b/c ---> 25*1/4 = 6.25 and 64*1/4 = 16
So 16*1/4 = 4 and 10*1/4 = 2.5, so e is the answer
14.) Dilation b/c you can either enlarge or reduce the pre-image.
15.) A heptagon has 7 lines of symmetry b/c it is equal to the number of sides

Answer:
The value of x=-8
Step-by-step explanation:
hope this helps.
Answer:
x = -8
Step-by-step explanation:
[tex]\frac{3}{4}(\frac{1}{4}x+8)-(\frac{1}{2}x+2) =\frac{3}{8}(4-x)-\frac{1}{4}x\\\\\frac{3}{4}*\frac{1}{4}x+\frac{3}{4}*8-\frac{1}{2}x-2 =\frac{3}{8}*4-\frac{3}{8}x-\frac{1}{4}x\\\\\frac{3}{16}x+3*2-\frac{1}{2}x-2 =\frac{3}{2}-\frac{3}{8}x-\frac{1}{4}x\\\\\\ \frac{3}{16}x+6-\frac{1}{2}x-2 =\frac{3}{2}-\frac{3}{8}x-\frac{1}{4}x\\\\\frac{3}{16}x-\frac{1}{2}x+\frac{3}{8}x+\frac{1}{4}x=\frac{3}{2}-4\\\\\\\frac{3}{16}x-\frac{1*8}{2*8}x+\frac{3*2}{8*2}x+\frac{1*4}{4*4}x=\frac{3}{2}-\frac{4*2}{1*2}\\\\\\[/tex]
[tex]\frac{3}{16}x-\frac{8}{16}x+\frac{6}{16}x+\frac{4}{16}x = \frac{3}{2}-\frac{8}{2}\\\\\frac{3-8+6+4}{16}x = \frac{3-8}{2}\\\\\frac{5}{16}x = \frac{-5}{2}\\\\x = \frac{-5}{2}*\frac{16}{5}\\\\x = -8[/tex]
write an equation in slope-intercept form for the line. slope=4,y-intercept=3
Answer:
y = 4x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 4 and c = 3, then
y = 4x + 3 ← equation of line
Enter the ordered pair for the vertices for T(3, –2)(QRST).
Given:
The figure QRST.
The rule of translation is [tex]T_{(3,-2)}(QRST)[/tex].
To find:
The coordinate of vertices after translation.
Solution:
According to the given rule of translation is [tex]T_{(3,-2)}(QRST)[/tex], we get
[tex](x,y)\to (x+3,y-2)[/tex]
From the given figure it is clear that the vertices of QRST are Q(1,3), R(3,-3), S(0,-2) and T(-2,1).
Using the above rule, we get
[tex]Q(1,3)\to Q'(1+3,3-2)=Q'(4,1)[/tex]
[tex]R(3,-3)\to R'(3+3,-3-2)=R'(6,-5)[/tex]
[tex]S(0,-2)\to S'(0+3,-2-2)=S'(3,-4)[/tex]
[tex]T(-2,1)\to T'(-2+3,1-2)=T'(1,-1)[/tex]
Therefore, the coordinates of the vertices after translation are Q'(4,1), R'(6,-5), S'(3,-4) and T'(1,-1).
The ordered pairs for the vertices of T(3, –2)(QRST) are
[tex]\mathbf{Q' = (4,1)}[/tex] [tex]\mathbf{R' = (6,-5)}[/tex] [tex]\mathbf{S' = (3,-4)}[/tex] and [tex]\mathbf{T' = (1, -1)}[/tex]
The coordinates of QRST are:
[tex]\mathbf{Q = (1,3)}[/tex]
[tex]\mathbf{R = (3,-3)}[/tex]
[tex]\mathbf{S = (0,-2)}[/tex]
[tex]\mathbf{T = (-2,1)}[/tex]
The transformation rule of [tex]\mathbf{T(3,-2)}[/tex] is:
[tex]\mathbf{(x,y) \to (x + 3,y -2)}[/tex]
So, we have:
[tex]\mathbf{Q' = (1 + 3,3 -2)}[/tex]
[tex]\mathbf{Q' = (4,1)}[/tex]
[tex]\mathbf{R' = (3 + 3,-3 -2)}[/tex]
[tex]\mathbf{R' = (6,-5)}[/tex]
[tex]\mathbf{S' = (0 + 3,-2 -2)}[/tex]
[tex]\mathbf{S' = (3,-4)}[/tex]
[tex]\mathbf{T' = (-2 + 3,1 -2)}[/tex]
[tex]\mathbf{T' = (1, -1)}[/tex]
Hence, the ordered pairs for the vertices of T(3, –2)(QRST) are
[tex]\mathbf{Q' = (4,1)}[/tex] [tex]\mathbf{R' = (6,-5)}[/tex] [tex]\mathbf{S' = (3,-4)}[/tex] and [tex]\mathbf{T' = (1, -1)}[/tex]

Alec says the sum of two numbers can never be less than either number.
Use a model to explain why Alec is incorrect,
Answer:
If you put two things together it cannot be less than what was originally there.
Step-by-step explanation:
For example if you have two bowls of soup and you add them together you will have more soup.
Alec is incorrect because this inequality of model 1 + 2 < 4 i.e. the sum of two numbers is greater than either number.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
Alec says the sum of two numbers can never be less than an either number.
Using a model a + b < c
Substitute the values a = 1, b = 2, and c = 4 in the inequality of model
1 + 2 < 4
So, the sum of two numbers is greater than either number.
Hence, Alec is incorrect.

The track team plans to buy new jerseys. If they buy more than 25 jerseys, the cost is $12.99 each. The total cost of the jerseys is a function of the number purchased, n. C(n) = 12.99n Use the drop-down menus to complete the statements below about the domain of this function.
Answer:
The answer is below
Step-by-step explanation:
A function shows the relationship between two variables (that is an independent variable and a dependent variable).
The domain of a function is the set of all input variables (that is independent variables).
Given the function C(n) = 12.99n, C(n) is the dependent variable representing the cost and n is the dependent variable which is the number of jerseys.
Since the customer has to buy more than 25 jerseys, the domain is:
Domain = 25 < n ≤ ∝
