(0,-1) (-5,-3)

-3-(-1) over -5-0 = 2/5 2/5 = m

y=mx+b

-3 = 2/5 times -5 +b

-3 = -2 + b

+2 +2

-1 = b

y=2/5x 1

Answer:

The system that can be used is:

$10x + 2y = 56$

$9x + 3y = 60$

Step-by-step explanation:

We have that:

x is the price of a package of sugar cookies, y is the price of a package of oatmeal cookies.

Shaikha sold 10 packages of sugar cookies and 2 packages of oatmeal cookies for $56.

This means that:

$10x + 2y = 56$

Khalid sold 9 packages of sugar cookies and 3 packages of oatmeal cookies for $60.

This means that $9x + 3y = 60$

System that can be used:

The system that can be used is:

$10x + 2y = 56$

$9x + 3y = 60$

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

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

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

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

$\\ \sf = 1.787$
