We need the values to answer this question
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.
Answer:
x = sqrt(273)/2 - 1/2 or x = -1/2 - sqrt(273)/2
Step-by-step explanation:
Solve for x:
x - 3 = 56/(x + 4)
Cross multiply:
(x - 3) (x + 4) = 56
Expand out terms of the left hand side:
x^2 + x - 12 = 56
Add 12 to both sides:
x^2 + x = 68
Add 1/4 to both sides:
x^2 + x + 1/4 = 273/4
Write the left hand side as a square:
(x + 1/2)^2 = 273/4
Take the square root of both sides:
x + 1/2 = sqrt(273)/2 or x + 1/2 = -sqrt(273)/2
Subtract 1/2 from both sides:
x = sqrt(273)/2 - 1/2 or x + 1/2 = -sqrt(273)/2
Subtract 1/2 from both sides:
Answer: x = sqrt(273)/2 - 1/2 or x = -1/2 - sqrt(273)/2
