Write an equation of the line that is parallel to y =
1
2
x + 3 and passes through the point (10, -5).

A) y = 2x - 15
B) y = -2x + 15
C) y = -
1
2
x
D) y =
1
2
x - 10

y=12x-125

Step-by-step explanation:

y=12x+3

parallel lines have same slopes,

y-y1=m(x-x1)

y-(-5)=12(x-10)

y+5=12x-120

y=12x-120-5

y=12x-125

a right triangle. and in the future use this desmos.com to you

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)
