10x + 9
because the -6x and positive 6x cancel out and all you have left is 2+2+5 and 10x
D=(b^2)-(4)(a)(c)
36-(4)(-2)(13)= 139
Answer:
Step-by-step explanation:
<u>How do you find the equation of a line parallel to another line?
</u>
<em>Method 1:</em> Using Slope Intercept Form
Substitute the slope from original line (3 in this case) into the equation of the line y = 3x + b.
Substitute the given point (1,7) into the x and y values 7 = 3(1) + b.
Solve for b (the y-intercept)
Substitute this value for 'b' in the slope intercept form equation y = 3x + 4.
<u>How do you find the Y intercept of a parallel line?
</u>
Step 1: Find the slope of the line. To find the slope of the given line we need to get the line into slope-intercept form (y = mx + b), which means we need to solve for y: The slope of the line 3x – 5y = 9 is m = 3/5. Therefore, the slope of the line parallel to this line would have to be m = 3/5.
Step-by-step explanation:
180 - (value of x) = answer
m° equal to c°
Step-by-step explanation:
6(2+y) = 3(3-y)
=>12+6y= 9-3y
=>6y+3y = 9-12
=>9y= -3
=> y = -1/3
