Answer:
x = - 10
Step-by-step explanation:
Given
10 - x = - 2x ( add 2x to both sides )
10 + x = 0 ( subtract 10 from both sides )
x = - 10
The coefficient of y∧15×∧2 in expansion of (y∧3+x)∧7 is (15×2)+(3×7)= 51
The slope of the line that contains the point (13,-2) and (3,-2) is 0
<em><u>Solution:</u></em>
Given that we have to find the slope of the line
The line contains the point (13,-2) and (3,-2)
<em><u>The slope of line is given as:</u></em>
Where, "m" is the slope of line
Here given points are (13,-2) and (3,-2)
<em><u>Substituting the values in formula, we get,</u></em>
Thus the slope of line is 0
