Given that f(x) = x2 + 2x + 3 and g(x) = quantity of x plus four, over three , solve for f(g(x)) when x = 2.
Sidana [21]
f(x)=x^2+2x+3
g(x)=\frac{x+4}{3}
f(g(x))=(\frac{x+4}{3})^2+2(\frac{x+4}{3})+3
f(g(x))=\frac{x^2+8x+16}{9}+\frac{2x+8}{3}+3
f(g(2))=\frac{2^2+8(2)+16}{9}+\frac{2(2)+8}{3}+3
f(g(2))+\frac{4+16+16}{9}+\frac{4+8}{3}+3
f(g(2))=\frac{36}{9}+\frac{12}{3}+3
f(g(2))=4+4+3
f(g(2)=11

Check:
g(2)=(2+4)/3=2
f(2)=2^2+2(2)+3=4+4+3=11  Checks.

Unknown angle problems (with ale<br> Solve for I in the diagrarn below.<br> (24 + 45)<br> f<br> TE
astraxan [27]

Answer:

x = 45

Step-by-step explanation:

The angles with (2x + 45) and x are supplementary angles, meaning they add up to 180°. We can write this statement as an algebraic equation of 2x + 45 + x = 180 and solve it.

Step 1: Combine like terms.

  • (2x+x)+45=180
  • 3x+45=180

Step 2: Subtract 45 from both sides.

  • 3x + 45 - 45 = 180 - 45
  • 3x = 135

Step 3: Divide both sides by 3.

  • 3x/3 = 135/3
  • x = 45

Step 4: Check if solution is correct.

  • 2(45) + 45 + 45 = 180
  • 90 + 90 = 180
  • 180=180

Therefore, x = 45.

Have a lovely rest of your day/night, and good luck with your assignments! ♡
