Answer:
64
Step-by-step explanation:
-4(m-n)^2
when m=3 and n=-1
-4(3-(-1))^2=
-4(3+1)^2=
-4(4)^2=
-4(16)=-64
correct answer is -64
Answer:
4x+11
Step-by-step explanation:
Assuming you mean g(x)=-6X-7
f(x)-g(x)
Replace f(x) with-2x+4 and g(x) with -6x-7
-2x+4 - (-6x-7)
Distribute the minus sign
-2x+4+6x+7
Combine like terms
-2x+6x+4+7
4x+11
Parallel is 2/5 Perpindicular is -5/2 Neither is -2/5 and 5/2
The answer is V = - 1/2. You need to subtract 5 on both sides -> 8v = 1-5 -> 8v=-4 and then divide by 8 to isolate the variable v to give you v=-1/2
