For this case we have the following functions:

f (x) = 3x\\g (x) = x ^ 2 + 1

We must find (f + g) (x). By definition of operations with functions we have to:

(f + g) (x) = f (x) + g (x)

So we have to:

(f + g) (x) = 3x + (x ^ 2 + 1)\\(f + g) (x) = x ^ 2 + 3x + 1

Answer:

(f + g) (x) = x ^ 2 + 3x + 1

sp2606 [1]

Answer:

a=12

Step-by-step explanation:

Pythagorean Theorem: a^{2}+b^{2}=c^{2}

In this case, a = 9, b = a, and c = 15.

9^{2}+a^{2}=15^{2}

81+a^{2}=225

The, we subtract 81 from both sides getting:

a^{2}=144,

Then, a=12

2x +y = 20~~....(i)\\\\6x -5y = -4~~....(ii)\\\\\\\text{Multiply equation (i) by 3:}\\\\6x +3y = 60~~...(iii)\\\\(iii)-(ii):\\\\6x+3y - 6x+5y = 60-(-4)\\\\\implies 8y = 60+4 = 64\\\\\implies y = \dfrac{64}8\\\\\implies y = 8\\\\\\\text{Substitute y =8 in equation (i):}\\\\2x+8 =20\\\\\implies 2x = 20-8 = 12\\\\\implies x = \dfrac{12}2 = 6\\\\\text{Hence (x,y) = (6, 8)}
