It seems like the total is 45° and one of the variables were 7.
A. -(a+5)
Because the negative sign is outside the parenthesis, multiplying by -1 just removes the negative sign:
-(a+5) * -1 = a+5
B. -(-x+31)
Apply the distributive property:
-(-x+31) becomes (- -x +31) which simplifies to (x+31)
multiply that by -1 to get -x+31
C. -(4x+12)
Because the negative sign is outside the parenthesis, multiplying by -1 just removes the negative sign:
-(4x+12) * -1 = 4x+12
The one that is on the top right is the one which is not a linear function
Answer:
y-b+am/m
Step-by-step explanation:
y-b=m(x-a)
y-b=MX-ma
mx=y-b+ma
x=y-b+ma/m
Answer:
Step-by-step explanation:
Your difference of perfect cubes formula is given as
and you have already correctly identified a as 
and b as 
. So we fill in the formula as follows:
and we simplify. Remember that
. It's important that you remember the rules.
Simplifying then gives us
That's it, so fill it in however you need to on your end. Learn the patterns for the sum and difference of cubes and it will save you a ton of headaches...promise!!
