Answer:
Lines are considered parallel if their slopes are the same. In Line 1, the slope is 5 and in Line 2, when we solve for 'y', we also get a slope of 5, which means the two lines are parallel.
Step-by-step explanation:
In order to find slope, it is easiest to put the equation in slope-intercept form, or y=mx + b, where m = slope and b=y-intercept. In L1, y=5x +1 indicates a slope of 5. In L2, the equation is not in slope-intercept form, so we must solve for 'y' using inverse operations: 2y - 10x +3 = 0, start by subtracting 3 from both sides of the equal sign: 2y - 10x +3 -3 = 0 - 3 gives us 2y - 10x = -3. Then add '10x' to both sides: 2y - 10x + 10x = -3 + 10x gives us 2y = 10x - 3. Lastly, divide all terms by 2: 2y/2 = (10/2)x - 3/2 or y = 5x - 1.5. Now that L2 is in slope-intercept form, we can see that m=5 as in L1, so since they have the same slope, they are parallel lines.
Answer:
352 students
Step-by-step explanation:
I'm not 100% sure how to answer this problem, like, what year is it exactly?
So what I did was averaged all the percentages to get 88%
I used that 88% to do 400 * 0.88 = 352
If the year is supposed to be 2013, then I recommend doing 400 * 0.89 = 356 students.
Hope this is helpful. :,)
