Answer:
y = - 1/2x + 5
Step-by-step explanation:
y = 2x – 6 slope = 2
Perpendicular line slope = -1/2
for (4 , 3) y = mx + b y = 3, x = 4, m = -1/2
b = y - mx = 3 - (-1/2) x 4 = 5
equation: y = - 1/2x + 5
Answer:
Step-by-step explanation:
Wave velocity of the sound = frequency * wavelength.
The frequency and wavelength depend on the medium through which the sound passes and they are both greater in the guitar string than in air as the string is denser than the air. So the sound travles faster through the guitar string.
32 mm = length × 100
(32 mm)/100 = length . . . . . divide both sides by 100
0.32 mm = length
The actual length of the organism is 0.32 mm.
Answer:
b + b + 7 = 23
2b + 7 = 23
Step-by-step explanation:
b = girls
b + 7 = boys
This is not an equation because it lacks an equal sign....so the only thing we can do here is combine like terms.
4 - 2x - 12 - 2x + 1 =
-4x - 7
