8x+4y=12 what is the slope intercept form

y = -2x +3

Step-by-step explanation:

Slope intercept form is y= mx+b where m is the slope and b is the y intercept

We need to solve the equation for y

8x+4y =12

Subtract 8x from each side

8x-8x+4y =-8x+12

4y = -8x+12

Divide each side by 4

4y/4 = -8x/4 +12/4

y = -2x +3

This is slope intercept form

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)

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
