Answer:
For (fg)(x)
(fg) (x) = 4x^4 - 8x^3 -11x^2 -3x
With no restrictions on the x
Step-by-step explanation:
To find (fg) (x) = f(x) . g(x)
We need to multiply f(x) with g(x)
(fg) (x) = (2x^2 -5x -3) * (2x^2 + x)
fg(x) = 4x^4 + 2x^3 - 10x^3 - 5x^2 -6x^2 -3x
fg(x) = 4x^4 - 8x^3 -11x^2 -3x
Answer:
5
Step-by-step explanation:
(4+20+x)/3 = (y+16)/2
2(24+x) = 3(y+16)
48 + 2x = 3y + 48
2x = 3y
Since x and y are positive integers, they can't be 0. To satisfy 2x = 3y
We'll have to use LCM of 2 and 3, which is 6 (or a multiple of 6)
For the least value, we use 6
To make both sides 6,
x = 3 and y = 2
Hence x + y = 5
Answer: Infinitely many solutions
Explanation:
Let's say we had this system
y = x+5
x-y = -5
Let's replace y with x+5 in the second equation
x-y = -5
x-(y) = -5
x-(x+5) = -5
x-x-5 = -5
0x-5 = -5
0-5 = -5
-5 = -5
We end up with a true statement since we get the same number on both sides. This system has infinitely many solutions. The two equations produce the same straight line graph. Effectively, the two lines overlap perfectly to intersect infinitely many times.
Notice how solving x-y = -5 for y leads to y = x+5. This is more evidence that both original equations are identical (just in different forms).
