Are the lines parallel, perpendicular, or neither? 3x-y=5 y=3x+1

erica [24]

Answer:

Parallel

Step-by-step explanation:

To be parallel it would have to be the exact same slope, perpendicular would be the opposite...these equations have the same slope so it is parallel.

$3x-y=5\\3x-5=y\\y=3x-5\\\\vs\\y=3x+1$

Two parrelel chords 16 centimeters and 30 centimeters long are 23 centimeters apart. find the length of the radius of the circle

BARSIC [14]

r^2 = 529 - 46x + x^2 + 64
r^2 = x^2 - 46x + 593
replace r^2 with (x^2+ 225)
x^2 + 225 = x^2 - 46x + 593
x^2 - x^2 + 46x = 593 - 225
46x = 368
x = 368/46
x = 8 cm
Find the radius
r^2 = 8^2 + 225
r^2 = 289
r =

r = 17 cm is the radius
