The x-intercepts occur when f(x)=0

x^2+4x-12=0 factor

x^2-2x+6x-12=0

x(x-2)+6(x-2)=0

(x+6)(x-2)=0

x=-6 and 2 or specifically the points (-6,0) and (2, 0)

(x+6)(x-2)

x=2 and x=-6.

Graph the solution to the inequality 2x-3y<18

frutty [35]

<, > - dotted line

≤, ≥ - solid line

$2x-3y\dfrac{2}{3}x-6\\\\y=\dfrac{2}{3}x-6-\text{It's a linear function}\\\\for\ x=0\to y=\dfrac{2}{3}(0)-6=0-6=-6\to(0;\ -6)\\\\for\ x=6\to y=\dfrac{2}{3}(6)-6=2(2)-6=4-6=-2\to(6;\ -2)$

Help me solve this equation 3x-7=4x

Sauron [17]

Hey!

Let's write it, $3x-7=4x$
Add $7$ to both sides,
$3x-7+7=4x+7$
$3x=4x+7$
Subtract $4x$ from both sides.
$3x-4x=4x+7-4x$
$-x=7$
Since we don't want a negative variable, we have to divide both sides by $-1$ .
$\frac{-x}{-1}=\frac{7}{-1}$
Our answer would be,
$x=-7$

Thanks!
