Yuri [45]

Step-by-step explanation:

<h3>✞︎Given</h3>

5(3-x)+1=3(x+4)

Solve Equation

<h3>✞︎Solution</h3>

$\tt\large\underline{15-5x+1=3x+12}$

$\large{✰} \bf \underline\color{purple}{16-5x=3x+12}$

$\tt\large\underline{\longmapsto16-12-3x+5x}$

$\tt\large\underline{\longmapsto4-8x}$

$\tt\large\underline{\longmapsto8x=4}$

$X=\longmapsto\sf \dfrac{\cancel{4}}{\cancel{8}}$

$\tt\large\underline{\longmapsto \: \: \: \: x = \frac{1}{2} }$

Hi,
If it is f(x)=2x²+3 and not F(x)=2x²+3 then
Answer D.

$f(x)=2x^2+3\\

f(x+1)=2(x+1)^2+3\\
=2(x^2+2x+1)+3\\
=2x^2+4x+5\\
