Answer:
x = (√6/√5) - 1
Step-by-step explanation:
- 10 x = 5x^2 -1
can be written as
5x² + 10x - 1 = 0
completing the square method :
for quadratic equation of the format ax² + bx + c = 0 ,
step 1, divide equation by a
therefore. dividing the equation by 5
=> x² + 2x - (1/5) = 0
=> x² + 2x = 1/5
c - 2b/4 = -1/5 - (2(2)/4) = -(6/5)
b/2 = 1
=> x² + 2x +1 = 6/5
=> (x + 1)² = 6/5
=> x = (√6/√5) - 1

1 2
2 0
y = -2(-1) + 4 = 2 + 4 = 6
y = -2(0) + 4 = 0 + 4 = 4
y = -2(1) + 4 = -2 + 4 = 2
y = -2(2) + 2 = -4 + 4 = 0

[tex]\text {Hey! Let's Solve this Equation!}[/tex]
[tex]\text {\underline {The First Step is to do Keep Change Change (KCC)}}[/tex]
[tex]\text {Keep: 4.25}\\\text {Change: - into +}\\\text {Change: 2.5x into -2.5x}[/tex]
[tex]\text {\underline {The Next Step is to Flip the Equation}}[/tex]
[tex]\text {Before: 4.25+-2.5x=14.75}\\\text {After: -2.5x+4.25=14.75}[/tex]
[tex]\text {\underline {The Next Step is to Subtract 4.25}}[/tex]
[tex]\text {-2.5x+4.25-4.25=14.75-4.25=10.5}\\\text {-2.5x=10.5}[/tex]
[tex]\text {\underline {The Final Step is to Divide -2.5}}[/tex]

[tex]\text {Best of Luck!}[/tex]
Hey there!☺
[tex]Answer:\boxed{x=-4.2}[/tex]
[tex]Explanation:[/tex]
[tex]4.25-2.5x=14.75[/tex]
Let's start by simplifying both sides in the equation.
[tex]4.25+-2.5x=14.75\\-2.5x+4.25=14.75[/tex]
Now we subtract 4.25 from both sides in the equation.
[tex]-2.5x+4.25-4.25=14.75-4.25\\-2.5x=10.5[/tex]
Now in our third/final step, we will divide both sides by -2.5.
[tex]\frac{-2.5x}{-2.5}= \frac{10.5}{-2.5}[/tex]
Now we simplify 10.5/-2.5.
[tex]\frac{10.5}{-2.5}=-4.2[/tex]
[tex]x=-4.2[/tex]

Please help. What is the slope for #2?
Answer: -4
Step-by-step explanation:
To find the slope, you want to use the slope formula [tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]. You can use any two points to solve. Let's use (-2,3) and (-1,-1).
[tex]m=\frac{-1-3}{-1-(-2)} =\frac{-4}{1} =-4[/tex]
Another way to tell is by looking at the arrows with a -4 written next to it. That also tells you what the slope is.
Which equation has the solution x =
3?
8x – 1= 23
Submit Answer
O 82 +1= 21
6x + 3= 81
6x + 7 = -25
Let's solve each equation for x
8x - 1 = 23
Add 1 to each side.
8x = 24
Divide both sides by 8
x = 3
Luckily, we already found the equation which has the solution of x = 3
The answer is: 8x - 1 = 23

Answer:
-11
Step-by-step explanation:
Answer:
[tex]x=-11[/tex]
Step-by-step explanation:
[tex]-1=\frac{\left(5+x\right)}{6}[/tex]
Switch sides:
[tex]\frac{\left(5+x\right)}{6}=-1[/tex]
Multiply both sides by 6:
[tex]\frac{6\left(5+x\right)}{6}=6\left(-1\right)[/tex]
[tex]5+x=-6[/tex]
Subtract 5 from both sides:
[tex]5+x-5=-6-5[/tex]
[tex]x=-11[/tex]
If M is the midpoint of segment AB, then which of the following statements is/are true? AB=MB AM=MB Segment AM is congruent to segment MB.
AB is the large segment.
AM is half of the large segment.
MB is the second half of the large segment.
AM = MB is true.
Segment AM is congruent to segment MB is true.
AB = MB is false.
The statements that are true.
-Segment AM is congruent to segment MB.
- AM = MB.
What is a midpoint of a line segment?The midpoint of a line segment is given as,
x = (a + c)/2
y = (b + d) / 2
Where (x, y) is the midpoint and (a, b) and (c, d) are the two endpoints.
We have,
If M is the midpoint of segment AB, then the following statements are true.
- AB = 2MB
Since M is the midpoint of AB, MB is half the length of AB.
Therefore,
AB is twice as long as MB.
- AM = MB
Since M is the midpoint of AB, AM, and MB are equal in length.
This is a property of the midpoint of a segment.
Now,
Segment AM is congruent to segment MB.
Since AM and MB are equal in length (as stated in statement 2), they are congruent to each other.
Therefore,
Segment AM is congruent to segment MB with AM = MB statement being true.
