Which equation represents a line which is perpendicular to the line 7x+4y=-24

y = 4/7x - 6

Step-by-step explanation:

Convert to y = mx + b form

  7x+4y=-24

  4y = -7x - 24

  y = -7/4x - 6

Perpendicular line is just the opposite inverse of the slope. Regular slope is -7/4, perpendicular slope is 4/7.

  y = 4/7x - 6

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

0.32
