Answer:

Step-by-step explanation:

Hey sweetie!

We are given two points: (-7, 9) & (5, 5)

And we are asked to find the slope

To do this only given two points use the Slope-Formula to solve for the slope

m = slope
m = y2-y1/x2-x1
m = 5-9/5–7
m = -4/12
m = - 1/3

The slope will be - 1/3

Final Answer: m = - 1/3

Answer:

A=8.4063 $u^{2}$

Step-by-step explanation:

Be the functions:

$y=\frac{3}{x};y=\frac{3}{x^{2}}:x=7$

according the graph:

$\int\limits^1_7 {\frac{3}{x} } \, dx -\int\limits^1_7 {\frac{3}{x^{2} } } \, dx =3\int\limits^1_7 {\frac{1}{x} } \, dx -3\int\limits^1_7 {\frac{1}{x^{2} } } \, dx=3(\int\limits^1_7 {\frac{1}{x} } \, dx -\int\limits^1_7 {\frac{1}{x^{2} } } \, dx)=3[lnx-\frac{1}{x}](1-7)=3[(ln7-ln1)-(\frac{1}{7}-1)]=3[(1.945-0)-(0.1428-1)]=3*(1.945+0.8571)=3*2.8021=8.4063u^{2}$
