2x+y=1 can be rewritten as y=-2x+1, with the slope as -2 and the y-intercept at 1. The equation you can use for the table would be (x*-2)+1, or you can just use this:
-2=5
0=1
3=-5
(-2, 5)
(0, 1)
(3, -5)
Answer:
6x-8
Step-by-step explanation:
to simplify you must distribute the parenthesis
so...
8x-16 -2x+8
now combine like terms
so..
8x-2x and 8-16
6x-8 is your final answer
hope this helps
82 = 100%
10% discount (90% of original price)
To find 90% find 10% and then subtract it from 82)
10% = 82/10 (8.2)
80-8.2=
71.8
<em>Answer:</em>
<em>For the first question the answer is : x = -10</em>
<em>And for the second question the answer is : x = 4</em>
<em>Step-by-step explanation:</em>
<em>For the first Equation :</em>
<em> 5(3x+2)-2 = -2(1-7x)</em>
<em> 15x +10-2 = -2 +14x</em>
<em> 15x + 8 = -2 + 14x</em>
<em>15x + 8 - 14x = -2 + 14x - 14x</em>
<em> x + 8 = -2</em>
<em> x+8-8 = -2 -8</em>
<em> x = -10</em>
<em>Answer : x = -10</em>

<em>For the second Equation :</em>
<em> 3x+2 = 14</em>
<em> 3x+2-2 = 14-2</em>
<em> 3x = 12</em>
<em> 3x/x = 12/3</em>
<em> x = 4</em>
<em>Answer : x = 4</em>
