X+2y=8
2y=8-x |:2
y=-\frac{1}{2}x+4
y=ax+b ==> y=-\frac{1}{2}x+4
We calculate the zeros of functions (0,b)
(0,b) = (0,4)
We have solution:
x=0, y=4

<em>If we put x = 0, we get</em>
<em>0 + 2y = 8</em>
<em>=> y = 8 / 2 = 4</em>

<em>if we put y = 0</em>
<em>x + 2 ( 0 ) = 8</em>
<em>=> x = 8</em>

<em>It means that solution set is { (0,4) , ( 8,0 ) }</em>

Answer:

106 m^2

Step-by-step explanation:

First multiply the shaded area:

12 * 10 = 120

Then multiply the white space:

7 * 2 = 14

Then subtract the white space from the shaded area to find the area of only the shaded area.

120 - 14 = 106

Final answer: 106 m^2

I hope this helps!

Answer:

  -15/16  

Step-by-step explanation:

The sum of a geometric series with first term a1 is ...

  S = a1/(1 -r)

Then the common ratio (r) is ...

  r = 1 -a1/S

For the given values, the ratio is ...

  r = 1 - 124/64 = -15/16

The common ratio is -15/16.
