Answer:
D. N(a) = (a + 20)/3
Step-by-step explanation:
A(n) = 3n - 20
A is a function of n. The inverse will be: N is a function of a.
Change A(n) to y and n to x.
y = 3x - 20
Switch x and y.
x = 3y - 20
Solve for y.
x + 20 = 3y
3y = x + 20
y = (x + 20)/3
Now switch y to N(a) and x to a.
Answer: N(a) = (a + 20)/3
No the congruence statements are sas,asa,sss, aas and hl
B is the correct answer y=x^2
Answer:
3x(x-1)
Step-by-step explanation:
3x^2-3x
3x(x-1)
Answer:A.
Step-by-step explanation:I think the answer is a because although it can be used to match it, it can't be used to match it exactly.
