3×-3y=6find the slope and y-intercept for each line

The slope of this line is 1 and the y-intercept is -2.

In order to find this, you need to put it in slope intercept form. This is done below for you.

3x - 3y = 6 > Subtract 3x from both sides

-3y = -3x + 6 > Divide by -3

y = x - 2

Now that you have this, you can find the slope by looking for the coefficient of x. In this case it is 1. You can find the intercept as the constant at the end, which is -2.

The y intercept would be -2 and the slope is 1. The formula is y=mx+b. So you would subtract 3x to the other side. Then you would divide -3 from y to both -3x and 6. Your y=mx+b would be y=x-2

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)

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
