Can someone please explain why x= -2! ASAP!!
9514 1404 393
Answer:
x = -2 because that is the value that makes the equation true
Step-by-step explanation:
Minus signs are everywhere. They can all be eliminated by multiplying both sides of the equation by -1.
-1(-x -6 -x) = -1(-2)
(-1)(-x) +(-1)(-6) +(-1)(-x) = 2 . . . . . distribute the -1
x + 6 + x = 2 . . . . . . . . simplify
x + x + 6 = 2 . . . . . . . . rearrange
(1 +1)x +6 = 2 . . . . . . . . factor, using the distributive property
2x +6 = 2 . . . . . . . . . . . simplify
2x +6 -6 = 2 -6 . . . . . . subtract 6 from both sides
2x = -4 . . . . . . . . . . . . . simplify
(2x)/2 = (-4)/2 . . . . . . . divide both sides by 2
x = -2 . . . . . . . . . . . . . . simplify
x is -2 because that is the value we get when we apply the properties of equality to the equation. We can check to see if it works in the original equation.
Check
-x -6 -x = -2
-(-2) -6 -(-2) = -2 . . . . put -2 where x is
2 -6 +2 = -2 . . . . . . . . simplify the signs
-4 +2 = -2 . . . . . . . . . . add the first two terms (could do all at once)
-2 = -2 . . . . . . . . yes, the value of x=-2 makes the equation true

Additional comment
The properties of equality we're concerned with here are the multiplication property of equality, the addition property of equality and the division property of equality. Respectively, these tell us that multiplying, adding, or dividing both sides of the equation by the same number doesn't change the value of the variable.
These properties are essential to understanding how algebra works.
A water tank holds 254.34 m cm3 of water. If
the diameter of the tank is 6 meters, calculate
the height
Answer:
Height, h = 9 m
Step-by-step explanation:
Given that,
The volume of a water tank, V = 254.34 m³
The diameter of the tank, d = 6 m
We need to find the height of the clinder. The volume of a cylinder is given by :
[tex]V=\pi r^2h\\\\h=\dfrac{V}{\pi r^2}\\\\h=\dfrac{254.34}{3.14\times (3)^2}\\\\h=9\ m[/tex]
So, the height of the cylinder is 9 m.

Is 4d + (15 + 3d) equivalent to (4d + 15) + 3d ?
Answer:
Yes it is
Step-by-step explanation:
4d + 3d = 7d so 7d + 15 would be the expression for both except it would only be 3d + 4d = 7d and 7d + 15 is the same as the first expression that I got from evaluating 4d + (15 + 3d).
______________________________
1.) Solve [tex]\bold{4d+(15+3d)}[/tex]:Combine 4d and 3d: [tex]=7d+15[/tex]2.) Solve [tex]\bold{(4d+15)+3d}[/tex]:Combine 4d and 3d: [tex]=7d+15[/tex]3.) Compare:[tex]7d+15=7d+15[/tex]
So your answer [tex]\bold{7d+15=7d+15}[/tex].

Which number best represents the slope of the graphed line?
y
+10
15
-10
-5
5
10
--5
-10
OA. -5
OB.
Ос.
OD. 5
maybe try -5 since the rise/run is 5/1 and the slope is negative
The slope of the graphed line is m = -5
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
Let the first point be P ( 0 , 2 )
Let the second point be Q ( 2 , -8 )
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 2 - ( -8 ) ) / ( 0 - 2 )
m = 10 / -2
m = -5
Hence , the slope is m = -5

2(3x – 1) = 6x – 2 number of solutions
Answer: All real numbers are solutions.
Step-by-step explanation:
Let's solve your equation step-by-step.
2(3x−1)=6x−2
Step 1: Simplify both sides of the equation.
2(3x−1)=6x−2
(2)(3x)+(2)(−1)=6x+−2(Distribute)
6x+−2=6x+−2
6x−2=6x−2
Step 2: Subtract 6x from both sides.
6x−2−6x=6x−2−6x
−2=−2
Step 3: Add 2 to both sides.
−2+2=−2+2
0=0
Answer:
2(3x – 1) = 6x – 2 number of solutions
