Answer:

$\frac{y_2-y_2}{x_2-x_1}=m=\frac{-5-3}{1_(_1)} \\ m=-\frac{8} {2}=-4\\ \frac{y-y_1}{x-x_1}=m\\ \fracp{y-3}{x+1}=-4\\y-3=-4(x+1)\\ y-3=-4x-4\\y=-4x-1$

You are applying fertilizer to a football field. The field is 360 feet long and 160 feet wide. You use 8 pounds of fertilizer pe

Assoli18 [71]

Answer: 10 bags

Step-by-step explanation:

First we must calculate the field area. Assuming it is a rectangle then its area equals the product of its length times its width

$A =360*160\\\\A = 57600 ft^2$

You use 8 pounds of fertilizer per 1,000 square feet

So the amount of fertilizer you should use is:

$57,600 ft^2 * \frac{8\ pounds}{1,000\ ft^2} = 460.8\ pounds$

As the fertilizer comes in bags of 50 pound then you need

$460.8\ pounds * \frac{1\ bag}{50\ pounds} = 9.2\ bags$

Since you can not buy 9.2 bags then we round up to the next whole number.

Finally you need 10 bags of fertilizer

Prove that 3(x+1)(x+7)-(2x+5)² is never positive

scZoUnD [109]

Step-by-step explanation:

3(x + 1)(x + 7) − (2x + 5)²

3(x² + 8x + 7) − (4x² + 20x + 25)

3x² + 24x + 21 − 4x² − 20x − 25

-x² + 4x − 4

-(x² − 4x + 4)

-(x − 2)²

A squared number is never negative (provided x is a real number), so -(x − 2)² is never positive.
