Brut [27]

2000 + 1500g ≤ 15000
1500g ≤ 15000 - 2000
1500g ≤ 13000
g ≤ 13000/1500
g ≤ 8 2/3

Therefore, the crane can safely lift a maximum of 8 2/3 cubic meters of gravel.

Line GH contains points G(–2, 6) and H(5, –3). What is the slope of ?

alexgriva [62]

We will use the slope formula and fill it in accordingly.

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Our x2 is 5 and x1 is -2; our y2 is -3 and y1 is 6

$m=\frac{-3-6}{5-(-2)}=\frac{-9}{7}$ .

The slope of your line is -9/7
