Answer:
-2
Step-by-step explanation:
2/3 (x-4)=2x
or, 2x-8/3 =2x (multiply(x-4) by 2/3)
or, 2x-8 =3×2x
or, 2x-8 =6x
or, 2x-6x = 8
or, -4x = 8
or, x= 8/(-4)
or, x= -2

Which of the following equations have no solution? Check all that apply.
6x + 1 = 3(2x – 4)
2 – 5x = 7x – 12
4(3 – x) = 2(6 – 2x)
5(x + 2) = 2(x – 4)
–4(x + 3) = 4(–x – 1)
Answer:
1 and 5
Step-by-step explanation:
1. 6x + 1 = 3(2x - 4)
6x + 1 = 6x - 12
6x + 13 = 6x
-6x -6x
13 = 0x
no solution
2. 2-5x = 7x - 12
2 = 12x - 12
14 = 12x
1 1/6 = x
3. 4(3 - x) = 2(6 - 2x)
12 - 4x = 12 -4x
-4x = -4x
x = ∞
4. 5(x + 2) = 2(x - 4)
5x + 10 = 2x - 8
3x + 10 = -8
3x= -18
x = -6
5. -4(x + 3) = 4( -x - 1)
-4x -12 = -4x -4
-4x - 8 = -4x
-8 = 0x
no solution

16r6sc/8r2s6 Which expression is equivalent to the given expression? Assume the denominator does not equal zero. A. B. C. D.
Answer:
B.
Step-by-step explanation:
The required expression is equivalent to the given expression is C.
An equivalent expression for 16r6sc/8r2s6 is to determine.
The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.
Numerator = it is the term positioned above in the ratio
Denominator = it is the term positioned below in the ratio
Here,
= 16r6sc/8r2s6
Factored 16 into 8 * 2
= 8*2r6sc/8r2s6
Rearrange the numerator in order to simplify relative to denominator.
=8r2s6c/8r2s6
8r2s6 are common in the denominator and the numerator of the ratio denominator does not equal zero so it implies
=c/1
Thus the required expression is equivalent to the given expression is C.

Which of the following equations represent linear function?
Answer:
click them all and whatever shows up right then keep that.. bc thats big ideas.. i know how that works
Step-by-step explanation:
Please help quickly
Let's see what to do buddy...
_________________________________ Step (1)
First we must find the measure of x
[tex](3x - 5) + (x + 1) = 180[/tex]
[tex]4x - 4 = 180[/tex]
Both sides plus 4
[tex]4x = 184[/tex]
Divided both sides by 4
[tex]x = \frac{184}{4} \\ [/tex]
[tex]x = 46[/tex]
_________________________________
Step (2)
Now we must find the RQS Angle measure :
Angle ( RQS ) = 46 + 1 = 47
_________________________________
Step (3)
QT bisects RQS ;
So the resulting angles are :
[tex] \frac{47}{2} = 23.5 \\ [/tex]
_________________________________
And we're done.
Thanks for watching buddy good luck.

Answer:
$836
Step-by-step explanation:
Add $75 and $89 together to get $164
Subtract $164 from $1,000.
1000 - 164 = 836

Help i really need some help for this!!!! Complete the equation so that it has infinitely many solutions.
13(3−z)
Answer:
13(3 - z) = 13(3 - z)
13(3 - z) = 39 - 13z
Step-by-step explanation:
To make the equation have infinitely many solutions, when you simplify, the equation will become z = z
To make this happen, the equation has to be the same on either side of the equal sign. Here are the two options :
13(3 - z) = 13(3 - z)
13(3 - z) = 39 - 13z

Step-by-step explanation:
So because it is a mixed number that means you want to have a whole plus a fraction. You keep the 5 as the whole and because 2/3=.666666. You add them together making 5 2/3.

What is the x-intercept of the slope of -2 and a y-intercept of 0, 6
Answer:
x- intercept = 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 = - 2 and c = 6 , thus
y = - 2x + 6 ← is the equation of the line
To find the x- intercept, let y = 0 in the equation and solve for x
- 2x + 6 = 0 ( subtract 6 from both sides )
- 2x = - 6 ( divide both sides by - 2 )
x = 3 ← x- intercept or (3, 0 )
2(x+6)=3(x+1)
Solving equations with variables on both sides. ;)
Step-by-step explanation:
2(x+6)=3(x+1)
2x+12=3x+3
collect the like terms
2x + 3x = 3+12
x=15/5=3
or
2x-3x = 3-12
= -9
Here are three lamps.
lamp C
lamp B
lamp A
Lamp A flashes every 20 seconds.
Lamp B flashes every 45 seconds.
Lamp C flashes every 120 seconds.
The three lamps start flashing at the same time.
How many times in one hour will the three lamps flash at the same time?
Answer with step-by-step explanation:
First of all, we need to calculate how many times the 3 lamps flash in a minute. We can do this by finding their LCM (least common multiple), which is 360. 360 is equivalent to 6 minutes, so that is going to be our test time. Lamp a flashes every 20 seconds, so 360/20 = 18 flashes. Then, 360/45 = 8 flashes. Finally, 360/120 = 3 flashes. 18 + 8 + 3 = 29 flashes per 6 minutes. If so, we multiply 29 by 10, because 60 minutes per hour ÷ 6 minutes = 10. So 29 × 10 = 290 flashes per hour
Hope this helped! (brainliest please)

Which theorem or postulate justifies this statement? angle6 cong angle13
A. vertical angles theorem
B. alternate interior angles theorem
C. alternate exterior angles theorem
D. corresponding angles postulate
E. linear pair postulate
Answer:
C. Alternate Exterior Angles Theorem
Step-by-step explanation:
I took the test
The corresponding angles postulate and the vertical angles theorem are proving ∠6 = ∠13. Therefore, options B and D are correct answer.
From the given figure, lines GN and FH are intersecting by the line segments KL and JM.
What are angles of parallel lines?Angles in parallel lines are angles that are created when two parallel lines are intersected by another line called a transversal.
From the given figure, we can see that
∠6 = ∠10 (Corresponding angles are congruent)
∠10 = ∠13 (Vertical angles are congruent)
Now, ∠6 = ∠10 = ∠13
The corresponding angles postulate and the vertical angles theorem are proving ∠6 = ∠13. Therefore, options B and D are correct answer.

Help!!! What is the equation of the following function? Show any work.
Answer:
[tex]y=-3(x+2)^2-3[/tex]
Step-by-step explanation:
Equation of the Quadratic Function
The vertex form of the quadratic function has the following equation:
[tex]y=a(x-h)^2+k[/tex]
Where (h, k) is the vertex of the parabola that results when plotting the function, and a is a coefficient different from zero.
The graph provided in the question, assumed as a parabola, has two clear points:
The vertex, located at (-2,-3)
The point (-1,-6)
Substituting the coordinates of the vertex, the equation of the function is:
[tex]y=a(x-(-2))^2-3[/tex]
[tex]y=a(x+2)^2-3[/tex]
The value of a will be determined by using the other point (-1,-6):
[tex]-6=a(-1+2)^2-3[/tex]
Operating:
[tex]-6=a(1)-3[/tex]
Solving:
a=-3
The equation of the graph is:
