All you do is multiply 300*.27=
81
-3x = 21
Divide -3 from both sides and you get x = -7
1/3x = 6
Divide 1/3 from both sides and you get x = 18
-1/2x = -7
Divide -1/2 from both sides and you get x = 14 (you get a positive answer from 2 negatives)
Dividing 1/3 is just multiplying by 3, and dividing -1/2 is just multiplying by -2
Answer:
<h2>y = -x - 1</h2>
Step-by-step explanation:
From the graph we have:
y-intercept = -1
x-intercept = -1
The slope-intercept form of an equation of a line:
<em>y = mx + b</em>
m - slope
b - y-intercept
Therefore we have: <em>y = mx - 1</em>
Put the coordinates of the x-intercept to the equation:
(-1, 0) → x = -1 and y = 0:
0 = -1m - 1 <em>add m to both sides</em>
0 + m = -m + m - 1
m = -1
Finally we have the equation:
<em>y = -1x - 1</em>
Answer:
<u><em>x=11</em></u>
