F(x)=4x+1
g(x)=x^2-5
(f . g)(x)=?
(f . g)(x) = f(x) . g(x) = (4x+1).(x^2-5)=(4x).(x^2)+(4x).(-5)+(1).(x^2)+(1).(-5)
(f . g)(x) = 4x^(1+2)-20x+x^2-5
(f . g)(x)=4x^3+x^2-20x-5
Answer: Option A. 4x^3+x^2-20x-5
X - y = 2
Rewriting in terms of y,
Subtract x from both sides.
-y = -x + 2
Divide by -1 so that the y is positive.
y = x - 2
Answer:
i think it is 3/5 raised (^) to the 2nd
Step-by-step explanation:
obvioulsy if its an exponent and seeing that you put it 2 time you have the original number and just raise its power by how many times its being multiplied! its easy, you got this champ!
Answer:
x = 10 months
Step-by-step explanation:
Equal when 10000 - 250x = 8000 - 50 x
2000 = 200x
x = 10
Answer:
m∠X = 29°
m∠V = 61°
m∠W == 90°⇒given
Step-by-step explanation:
∵ ΔXWV is right angle at W
∴ m∠W = 90°
∴ m∠X + m∠V = 180° - 90° = 90°
∵ m∠X = 2x + 5 and m∠V = 4x +13
∴ 2x + 5 +4x + 13 = 90
∴ 6x + 18 = 90
∴ 6x = 90 - 18 =72
∴ x = 72/6 = 12
∴ m∠X = 2(12) + 5 = 29°
∴ m∠V = 4(12) + 13 = 61°
