How do you solve the inequality 6y+3> -18x

Alex17521 [72]

$6y + 3 \ \textgreater \ - 18 x$

Subtract 3 from both sides:

$6 y + 3 - 3 \ \textgreater \ - 18 x - 3$

$6y \ \textgreater \ - 18 x - 3$

Dividade both sides by 6 :

$\frac{6y}{6} \ \textgreater \ \frac{-18x-3}{6}$

$y \ \textgreater \ \frac{-18x-3}{6}$

hope this helps!

Find the area of the triangle whose vertices are (2, 3); (-1, 0); (2, -4)...

Neko [114]

Answer:

Area = 14.5

Step-by-step explanation:

Let's label the given coordinates A, B, C;

Thus;

A = (2, 3)

B = (-1, 0)

C = (2, -4)

From the coordinate geometry formula, the formula for area of a triangle with 3 vertices is;

Area = [Ax(By - Cy) + Bx(Cy - Ay) + Cx(Ay - By)]/2

Area = [2(0 - (-4)) + (-1)(-4 - 3) + 2(3 - (-4))]/2

Area = 29/2

Area = 14.5
