Answer: B) Linear; it can be written as y = -3x-6

We subtract 6 from both sides to go from the original equation to -3x-6 = y

Then we flip both sides to end up with y = -3x-6

This is in slope intercept form y = mx+b with m = -3 as the slope and b = -6 as the y intercept.

Bill ate 1/4 pound of trail mix on his first break during a hiking trip. On his second break, he ate 1/6 pound. How many pounds
tino4ka555 [31]
Since we know that he ate 1/4 pound one time, and 1/6 another time, we have to add up the fractions. 

1/4+1/6

LCM of 4 and 6 = 12

3/12 + 2/12 

Add the numerators: 

5/12

So, he ate 5/12 of a pound of bars in both breaks. 

Hope this helps!

1.3n-0.03=-9 (solve for n) grade lvl. 7

Hello from MrBillDoesMath!

Answer:

-6.9


Discussion:  

1.3n - 0.03 = -9     =>              multiply both sides by 100

130n - 3 = -900 =>

130n = -900 +3 =  -897 =>     add 3 to both sides

n = -897/130  =>

n =  - (69 * 13)/ (10*13) =>

n = - 69/10 = - 6.9




Thank you,

MrB
