Answer:
x = 3 x = -5
Step-by-step explanation:
2|x+1|=8
Divide each side by 2
2/2|x+1|=8/2
|x+1| = 4
There are two solutions to an absolute value, one positive and one negative
x+1 = 4 x+1 = -4
Subtract 1 from each side
x+1 -1 = 4-1 x+1-1 = -4-1
x = 3 x = -5
Answer:
x=3 and -5
Step-by-step explanation:
to start with when you work with equations there will be two answers, no solution set or the answer will be 0. in this case there are two answers.
2/x+1/=8(first you remove all the things that are extra to the equation)
2 2
/x+1/=4 in this case it has two answers because 4 is greater than 0.
so you remove the bracket.
x+1=4 or x+1=-4
x=4-1 x=-4-1
x=3 x=-5
what is
y= -4/7x + 2 in
standard form
using integers
Answer:
4x + 7y = 14
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Given
y = - [tex]\frac{4}{7}[/tex] x + 2 ( multiply through by 7 to clear the fraction )
7y = - 4x + 14 ( add 4x to both sides )
4x + 7y = 14 ← in standard form

I got x=6 on an online algebra calculator.
Step-by-step explanation:
Answer:
x=6
Step-by-step explanation:
2(3x+2) can be expanded = 6x+4
6x+4=2x+28
then you want to minus 4 from both sides
6x=2x+24
then you can minus 2x from both sides
4x=24
then you can divide both sides by 4
x=6

3x+2y=19
-9x+8y=-29
Step-by-step explanation:
(3x + 2y =19)(3)
-9x + 8y =-29
9x + 6y = 57 NOTE: we cross here 9x in first
-9x + 8y = -29 we cross here - 9x in second
Since 9x and - 9x are opposite
___________
6y +8y = 57 - 29
14y = 28
Y=28/14
Y=2
Replace y in second equation of this system:
-9x + 8y = - 29
-9x +8(2)= - 29
-9x + 16 = - 29
-9x = -29 - 16
-9x = - 45
X= -45/-9
X=5

The area of a square plot of land is 325 square meters. What is the perimeter of the square, in meters? Express your answer in simplest radical form.
Hey there! I'm happy to help!
The first thing to do is find the square root of the area so we know what one of the sides are. Since our answer is supposed to have a radical, we don't need to simplify the radical.
So, each side is just √325.
Now, we multiply this by four to find the perimeter.
4√325
However, we can simplify that. To do this, we will find all of the prime factors of 325. If there are two of a certain number, we will take that number and pull it to the outside of the radical and cancel out both of the numbers inside the radical. So, if you had two 2's inside the radical, you would cancel them out and put a single two on the outside.
4√5×5×13
We can put the five outside
4×5√13
The perimeter is 20√13.
I hope that this helps! Have a wonderful day!

What is mean by Rectangle?A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
Given that;
The area of a square plot of land is 325 square meters.
We know that;
Area of square with side 'a' is,
⇒ Area = a²
Here, The area of a square plot of land is 325 square meters.
Hence, We get;
⇒ a² = 325
⇒ a = √325
⇒ a = 18.02 meters
Hence, The perimeter of a square plot of land is,
⇒ Perimeter = 4a
⇒ Perimeter = 4 × 18.02
⇒ Perimeter = 72.08 meters

Question 15 options:
785.0 cm3
7850.0 cm3
2616.67 cm3
261.67 cm3
Step-by-step explanation:
First, we need to know the formula for finding the volume of a cone.
[tex]V = \frac{1}{3} \pi r^2h[/tex]
[tex]V=volume\\r=radius\\h=height[/tex]
Now that we know the formula for finding the volume of a cone, we can look at the given information from the diagram and plug them into the formula.
Height = 25 cmRadius = 10 cm[tex]V=\frac{1}{3} \pi (10)^2(25)[/tex]
[tex]V=\frac{1}{3} \pi (100)(25)[/tex]
[tex]V=\frac{1}{3} \pi (2500)[/tex]
[tex]V=2616.6666...[/tex]
[tex]V = 2616.67[/tex]
Lastly, add the measurement units to the final answer which is cm³.
With that being said, the volume of the cone is 2616.67 cm³ which is letter choice C.
