Im not sure this question is complete but the answer should be <u><em>152.4</em></u>
Answer:
30
Step-by-step explanation:
- How much was the decrease from Figure A to Figure B (let x be the decrease): 45x = 27
- Divide each by 45 to cancel out the 45 next to x. It should now look like this: x = 3/5
- To find x, we would normally multiply x by 3/5, but because we don't have x, we just DIVIDE 18 by 3/5: 18 ÷ 3/5 = 30
- So, x = 30
I hope this helps!
680.6/820 = 0.83
0.83 = 83%
Parallel lines have the same slope, so since you want a line that is parallel to a line with slope -8, your line will also have slope -8.
The slope-intercept form of the equation of a line is
y = mx + b
where m is the slope, and b is the y-intercept.
You already know you have a slope of -8, so m = -8, and you have
y = -8x + b
Now you need to find the value of b.
Use the point you know and substitute it in for x and y, and solve for b.
y = -8x + b
Use x = -8, and y = 2.
2 = -8(-8) + b
2 = 64 + b
-62 = b
b = -62
Now replace b with -62.
y = -8x + b
y = -8x - 62
