Find the x-intercept and y-intercept of the line. 3x + 5y = −15

The x intercept  is (-5,0)

The y intercept  is (0,-3)

Step-by-step explanation:

To find the x intercept we set y=0 and solve for x

3x+5y = -15

3x+0 = -15

3x = -15

Divide by 3

3x/3 = -15/3

x = -5

The x intercept  is (-5,0)

To find the x intercept we set x=0 and solve for y

3x+5y = -15

0+5y = -15

5y = -15

Divide by 5

5y/5 = -15/5

y = -3

The y intercept  is (0,-3)

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)
