Answer:
The right side of the equation is only a different way of writing the left side, so any value of x will solve this equation.
The equation − 2 ( x + 3 ) = − 2 x − 6 does not have any specific solutions for the simple reason that the left and rigth sides are two representations of the same equation.
We have − 2 ( x + 3 ) means that each term inside the parenthesis should be multiplied with − 2 , i.e.
− 2 ( x + 3 ) = − 2 ⋅ x − 2 ⋅ ( + 3 ) = − 2 x − 6
Which is exactly what the right side says.
Any value of x will, therefore, fulfill this equation.

Answer:
median = 9.5
range = 11
Step-by-step explanation:
mean = (sum of numbers)/(number of numbers)
(18 - x + x - 3 + x + x/2 + 5 + 4x - 10 + 2x - 1)/6 = 9
9 + 7x + x/2 = 54
7x + x/2 = 45
14x + x = 90
15x = 90
x = 6
Now we can write the 6 numbers.
12, 3, 6, 8, 14, 11
We write the numbers is increasing order.
3, 6, 8, 11, 12, 14
The median is the mean of the 2 middle numbers.
median = (8 + 11)/2 = 19/2 = 9.5
The range is the difference between the larges and smallest of the numbers.
range = 14 - 3 = 11

Write an equation of the line containing the given point and parallel to the given line.
(6,-9); 3x - 2y = 9
Answer:
y = 3/2x - 18
Step-by-step explanation:
3x - 2y = 9
-2y = -3x + 9
y = 3/2x - 9/2
y = 3/2x + b
-9 = 3/2(6) + b
-9 = 9 + b
-18 = b
6.) What is the sum of 3x² + x+8 and x? - 9 ?
Step-by-step explanation:
= (3x² + x + 8) + (x² - 9)
= (3 + 1)x² + x + (8 - 9)
= 4x² + x - 1

Step-by-step explanation:
Answer:
Sal will have at least 5 dollars for every meal.
Step-by-step explanation:
Sal will have 5 dollars for every meal because, In the sentence, It says, The profits are the same. Each thing costs $3 and $2 for each meal which is five.

Which expression has the same value as-18 divided by (-9)?
0 -18 divided 2
0-12 divided (3)
0-10 divided 5
0 -8 divided (-4)
Answer:
4th answer
(-8 divided by -4)
Step-by-step explanation:
First , Let's find the value of (-18) divided by (-9)
Before that we have to know,
[tex]\frac{(+)}{(-)} =(-)[/tex]
[tex]\frac{(-)}{(-)} =(+)[/tex]
[tex]\frac{(+)}{(+)} =(+)[/tex]
[tex]\frac{(-)}{(+)} =(-)[/tex]
Now let's find for the answer for the above
[tex]\frac{(-18)}{(-9)} =2[/tex]
And now let's find which expression has the same value as the question
#1
[tex]\frac{(-18)}{2} =(-9)[/tex]
#2
[tex]\frac{(-12)}{3} =(-4)[/tex]
#3
[tex]\frac{(-10)}{5} =(-2)[/tex]
#4
[tex]\frac{(-8)}{(-4)} =2[/tex]
So, it's clear for you that only the 4th expression will the same answer as the question.

solve the equation. -5 (m + 4) = 27
Answer:
m = -9.4
Step-by-step explanation:
Distribute -5 to m and 4.
You should have -5m-20=27
Add 20 to both sides.
You should end with -5m=47
Divide both sides by -5.
You should get m= -9.4

Heya!
- If the line y = mx + c passes through the point of intersection of the lines x - 2y = -1 and y = 2 and is perpendicular to the line y = 4x + 8 , then find the values of m and c.
Help!! Irrelevant / Random answers will be reported*
Answer:
Hey There!
Let's solve...
We know that the given line is
[tex]y = 4x + 8 \\ [/tex]
Slope is
[tex]m_{g} = 4 \\ [/tex]
The answer is perpendicular to m which is the negative reciprocal of m_g
[tex]m = - \frac{1}{ m_{g} } = - \frac{1}{4} \\ [/tex]
[tex]y = 2 \\ x = 2(2) = - 1 \\ x = 4 - 1 = 3 \\ x = 3[/tex]
The intersection point is
(3,2)
If we substitute the point into
[tex]y = mx + c \\ y = - \frac{1}{4}x + c \\ [/tex]
Now let's solve y intercept...
[tex]2 = - \frac{1}{4}(3) + c \\ \\ c = 2 + \frac{3}{4} \\ [/tex]
[tex] = \frac{8}{4} + \frac{3}{4} \\ \\ = \frac{8 + 3}{4} = \frac{11}{4} [/tex]
Now the required lines are
[tex]y = - \frac{1}{4}x + \frac{11}{4} \\ \\ m = - \frac{1}{4} \\ \\ c = \frac{11}{4} [/tex]

A straight line PQ passing through points (1,-6) and (6, 14). Determine whether a straight line which passing through (-4,-8) and (-1,7) is parallel to PQ. Explain your answer. [3 markah / marks)
Answer:
line not parallel to PQ
Step-by-step explanation:
Parallel lines have equal slopes
Calculate slopes m of both lines using slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (P (1, - 6) and (x₂, y₂ ) = Q (6, 14 )
[tex]m_{PQ}[/tex] = [tex]\frac{14-(-6)}{6-1}[/tex] = [tex]\frac{14+6}{5}[/tex] = [tex]\frac{20}{5}[/tex] = 4
Repeat with (x₁, y₁ ) = (- 4, - 8 ) and (x₂, y₂ ) = (- 1, 7 )
m = [tex]\frac{7-(-8)}{-1-(-4)}[/tex] = [tex]\frac{7+8}{-1+4}[/tex] = [tex]\frac{15}{3}[/tex] = 5
Since slopes are not equal then lines are not parallel

Given side AB in ΔABC has length x, what is the length of side AC?
A) x B) x 2 C) x 3 Eliminate D) 2x
The length of AC from the given diagram is 14.0cm
Find the diagram attached below;
From the diagram, we need to first find the value of side AB using the SOH CAH TOA identity
Given the following
Opposite = x
Adjacent = 9cm
Angle of depression = 50 degrees
Tan theta = opposite/adjacent
Tan 50 = x/9
x =9tan 50
x = 10.73
Get the hypotenuse using the pythagpras theorem
AC = √AB²+BC²
AC = √10.73²+9²
AC = √196.04
AC = 14.00
Hence the length of AC from the given diagram is 14.0cm

What is an equation of a line?The equation of a straight line is y = mx+c, m is the gradient and c is the height at which the line crosses the y-axis, also known as the y -intercept.
Given is a graph, of a line passing from (0, 0) and (15, 3), we need to find the equation of the line,
We know that, the equation of a line passing through two points (x₁, y₁) and (x₂, y₂) is given by:

Jacob covered a cylindrical can with paper for a project. The can is 12 centimeters tall and has a 6 centimeter radius. Which is closest to the minimum amount of paper Jacob needs to cover the entire can?
The minimum amount of paper Jacob needs to cover the entire can is 678.6 cm²
The radius (r) of the can is 6 cm and the height (h) of the can is 12 cm. Hence:
Surface area (SA) = 2πr² + 2πrh
SA = 2π(6)² + 2π(6)(12)
SA = 678.6 cm²
The minimum amount of paper Jacob needs to cover the entire can is 678.6 cm²

You have 63.50. You earn additional money by raking leaves. Then you buy a sweatshirt for 44.99 and have 53.51 left. How much money do you earn by raking leaves?
Answer:
you earned 35 dollars raking leaves.
start with 63.50 and subtract the 44.99.
63.50-44.99=18.51.
then subtract the 53.41 dollars from 18.51 and get 35.
51.41-18.51=35
Answer: $35
Step-by-step explanation:
lets create an equation
x is going to be the amount of money gained by raking leaves
(63.50 + x) - 44.99 = 53.51
now remember, whatever you do to one side, you do to the other side.. oppositely.
so lets add 44.99 to both sides, either side of the equal sign, because the opposite of -44.99 is +44.99
63.50 + x = 98.50
now subtract 63.50 from both sides
x = 35
