Answer:
x = 12
y = 4√10
z = 12√10
Step-by-step explanation:
The geometric mean rules apply. Each of the segments labeled with a letter is the geometric mean of the segments it touches on the hypotenuse.
x = √(4×36) = 12
y = √(4×(4+36)) = 4√10
z = √(36×(36+4)) = 12√10
Answer:
Step-by-step explanation:
Let the numbers be x and y
<u>Three times the first number minus two times the second number equals -7:</u>
<u>The second number equals one less than negative three times the first number:</u>
<u>Substitute y in the first equation and solve for x:</u>
- 3x - 2(-3x - 1) = -7
- 3x + 6x + 2 = -7
- 9x = -9
- x = -1
<u>Find the value of y:</u>
- y = -3(-1) - 1
- y = 3 - 1
- y = 2
The numbers are -1 and 2
Answer:
units
Step-by-step explanation:
Calculate the distance d using the distance formula
d = 
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (- 9, 5)
d =
