Help please? Graphs just are not my thing.

There is no linear function that all of those points fit.

There are formal approximations ... such the "least squares" one ...
that can best approximate the group of points according to some rule.
But there's no straight-line that hits all of the points. Just mark them
on a graph, and you'll see that right away.

The GCF (Greatest Common Factor) of 45 and 75. Show your work too. Thanks for your help!

Studentka2010 [4]

$45=3 \cdot 3 \cdot 5 \\
75=3 \cdot 5 \cdot 5$

The GCF is $3\cdot 5 =15$ .

If √2 = 1.414 then the value of 5+√2 / 5-√2 is

Gala2k [10]

Answer:

1.787

Step-by-step explanation:

$\\ \sf \frac{5 + \sqrt{2} }{5 - \sqrt{2} } \times \frac{5 + \sqrt{2} }{5 + \sqrt{2} }$

$\\ \sf = \frac{(5 + \sqrt{2}) }{5 - \sqrt{2} } \times \frac{(5 + \sqrt{2}) }{5 + \sqrt{2} }$

$\\ \sf = \frac{25 + 5 \sqrt{2 } + 5 \sqrt{2} + 2 }{( {5})^{2} - ( \sqrt{ {2}})^{2} }$

$\\ \sf = \frac{27 + 10 \sqrt{2} }{25 - 2}$

$\\ \sf = \frac{27 - 10 \sqrt{2} }{23}$

Now putting the value of√2

$\\ \sf = \frac{27 + 10 \times 1.414}{23}$

$\\ \sf = \frac{27 + 14.14}{23}$

$\\ \sf = \frac{41.14}{23}$

$\\ \sf = 1.787$
