Answer:

It is a solution

Step-by-step explanation:

Given

$y + 4 > 3x-1$

Required

Is $(-1,4)$ a solution

$(-1,4)$ implies that:

$x=-1\ \ \y = -4$

Substitute in:

$y + 4 > 3x-1$

$-4 + 4 > 3 * -1 -1$

$-4 + 4 > -3 -1$

$0 > -4$

The above inequality is true.

<em>Hence, </em> $(-1,4)$ <em> is a solution y + 4 > 3x-1</em>

Find the area of the figure.

$\huge \bf༆ Answer ༄$

At first Divide the figure into two rectangles, I and Il

Area of figure l is ~

$\sf24 \times (40 - 30)$

$\sf24 \times 10$

$\sf240 \: \: ft {}^{2}$

Area of figure ll is ~

$\sf 18 \times 30$

$\sf540 \: ft{}^{2}$

Area of whole figure = Area ( l + ll )

that is equal to ~

$\sf240 + 540$

$\sf780 \: \: ft{}^{2}$
