Answer:
Mean proportional = 1/8
Step-by-step explanation:
Mean proportional is nothing but geometric mean of two numbers.
Geometric mean of any two numbers x & y is calculated as -
G = √(x × y)
Here, considering x = 1/16 and y = 9/36 = 1/4,
G = √(1/16 × 1/4)
G = √(1/64)
G = 1/8

Trying to factor as a Difference of Squares:
2.1 Factoring: 9x
-1
Theory : A difference of two perfect squares, A
- B
can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A
- AB + BA - B2 =
A
- AB + AB - B2 =
A
- B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 9 is the square of 3
Check : 1 is the square of 1
Check : x
is the square of x1
Factorization is : (3x + 1) • (3x - 1)
Final result :
(3x + 1) • (3x - 1)
Answer:
Parallel lines NEVER intersect.
Perpendicular lines intersect at a right angle (90 degrees)
Step-by-step explanation:
Here we see that the line with the point E on it is parallel to the one with points B and D.
These lines will NEVER intersect.
I hope this helps!
Answer:
Putting the value of x= 2 in the first equation,
6(2)+y= 17
y= 17-12 = 5
This value is same as the value for y given in the question.
Therefore, it satisfies the equation.
Again, putting the value of x= 2 in the second equation,
3(2)+14y= 16
14y= 16-6 = 10
y= 10/14 = 5/7
It doesn't satisfies the 2nd equation
Hence, (2,5) is not the solution to this system.
