Answer:
x2-30x-21=0
Step-by-step explanation:
x =(30-√984)/2=15-√ 246 = -0.684
x =(30+√984)/2=15+√ 246 = 30.684
Answer:
y - 3 = -8(x + 7)
Step-by-step explanation:
The equation of a line with slope m through point (h, k) is ...
y -k = m(x -h)
__
The slope you want is m = -8, which is the slope of the given line.* The given point is (h, k) = (-7, 3), so the equation you're looking for is ...
y - 3 = -8(x -(-7))
The expression inside parentheses can be simplified so you have ...
y - 3 = -8(x + 7)
_____
* The given line is in "slope-intercept" form, which is y = mx + b. Matching this pattern to the given equation, you see that m=-8. Parallel lines have equal slope, so -8 is the slope of the line you're writing the equation for.
