Answer:
the answer to the first one is A
the second one is 2
the last one is A
this just wants us to calculate 4/5-1/3
make common denom
4/5 times 3/3=12/15
1/3 times 5/5=5/15
4/5-1/3=12/15-5/15=(12-5)/15=7/15
7/15lb is left
Answer:

Step-by-step explanation:
The slope-intercept form:

m - slope
b - y-intercept
We have

Parallel lines have the same slope. Therefore we have the equation:

The line passes through the point (-3, -5). Put the coordinates of the point to the equation and solve it for b:

<em>add 1.8 to both sides</em>

Finally we have:

Add the two equations together and combine like terms
Answer:
9x^4=6,561x
6x^2=36x
6561x+36x=6597x
Step-by-step explanation:
9x to the 4th power is just 9x9=81x9 and so on and the same goes for 6 then you just add them. Not Sure if this is the way you needed but feel free to ask anything.
