Answer:
10√5
Step-by-step explanation:
The geometric mean of two numbers is the square root of their product.
m = √(20×25) = √500 = √100 × √5
m = 10√5
The geometric mean of 20 and 25 is 10√5.

Solve the system by elimination 2x-3y=23 x+3y=-20
Answer:
x = 1
y = -7
Step-by-step explanation:
2x-3y=23
+ x+3y =-20
3x + 0 = 3
x = 1
(1) + 3y = -20
-1 -1
3y = -21
y = -7

What is the solution set for StartAbsoluteValue 4 minus StartFraction x over 2 EndFraction EndAbsoluteValue = 8?
A.x = negative 24 and x = negative 8
B.x = negative 24 and x = 24
C.x = negative 8 and x = 8
D.x = negative 8 and x = 24
The solution to the set is .x = negative 8 and x = 24.
What is Absolute value?The separation of a number from a number line's origin is referred to as a number's absolute value. It is denoted by the symbol |a|, which specifies the size of any integer 'a'. Any integer's absolute value, regardless of its sign or whether it is positive or negative, will be a real number. The modulus of a, which is how two vertical lines |a| are used to symbolise it.
Given:
|4 - x/2| = 8
So, there are two possibilities
4- x/2 = 8 or 4 - x/2 = -8
-x/2 = 8-4 or -x/2 = -8-4
-x/2 = 4 or -x/2 = -12
x= -8 or x= 24
Hence, the solution to the set is .x = negative 8 and x = 24

18.1
17.3
15.9
16.4
Answer:
17.3
Step-by-step explanation:
To solve this equation, you need to use the pythagorean theorem which is:
[tex]a^{2} +b^{2}= c^{2}[/tex]
a= length
b= height
c= hypotenuse
First, substitute in your values for the equation:
[tex]10^2+b^{2} =20^{2}[/tex]
Then, use the squares in the equation:
[tex]100+b^{2} =400[/tex]
Then, subtract 100 from both sides to isolate b:
[tex]b^{2} =300[/tex]
Finally, square root both sides to get your answer:
[tex]b=17.3205080757[/tex]
Then round to the nearest tenth which gives you 17.3.

the two lines below are parallel if the slope of the red line is 5 what is the slope of the green line
Answer:
5
Step-by-step explanation:
Since the two lines are parallel, they must have the same slope. This means that the slope of green line must be 5 just like the red line. You can also use the slope formula (rise/run) or change in y divided by change in x.
