The x-intercept of the line whose equation is 2x - 3y = 6 is

kati45 [8]

2x - 3y = 6
To find the x-intercept, plug zero in for y and solve.
2x - 3(0) = 6
2x = 6
divide both sides by 2
x = 3
The ordered pair is (3,0)

Calculus question....does anyone know how to solve this?

$h(x)=(f\circ g)(x)$
$\sqrt{x+5}=\sqrt{g(x)+2}$
$x+5=g(x)+2$
$g(x)=x+3$

Just to check this is correct:

$(f\circ g)(x)=f(g(x))=f(x+3)=\sqrt{(x+3)+2}=\sqrt{x+5}=h(x)$
