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.
Answer: x=10
Step-by-step explanation: Hope this help :D
1/2 can also be written as 0.5, so you're asking what 6.5% of 580 is. To get 1% you divide by 100 which is 5.8. You can then multiply 5.8 by 6 to get 34.8 (6%). To get 0.5%, you halve 5.8 to get 2.9. Then, you add 2.9 and 34.8 which is 37.7, and that should be your answer! Hope this helped!
