It is A, because a direct proportion follows the rule y=kx, and in A, k = 12 and it works for all of the x and y values
Answer:
f=25
Step-by-step explanation:
24+1=25
25-1=24
Answer:
Step-by-step explanation:
(3x – 5)(–x + 4)
(3x)(–x) + (3x)(4) + (–5)(–x) + (–5)(4).
-3x^2+12x +5x -20
-3x^2+ 17x -20
Answer:
-30x^2-9x+12 all real numbers
Step-by-step explanation:
f(x) = -6x + 3 and g(x) = 5x + 4
f(x) * g(x) = (-6x + 3) * ( 5x + 4)
FOIL
= -30x^2 -24x+15x +12
Combine like terms
=-30x^2-9x+12
The domain is what numbers x can take
There are no restrictions so all real numbers
Hello from MrBillDoesMath!
Answer:
Binomial with a degree of 6 (the second Choice)
Discussion:
(a^3b+9a^2b^2-4ab^5) - (a^3b-3a^2b^2+ab^5) =
(-4ab^5- ab^5) + ( a^3b-a^3b) + ( 9a^2b^2 + 3a^2b^2) =
(-4ab^5- ab^5) + 0 + ( 9a^2b^2 + 3a^2b^2) =
12 a^2 b^2 - 5 a b^5
This is a binomial with degree 6 (degree of last term = 1 + 5 = 6).
Thank you,
MrB
