Answer:
14 points
Step-by-step explanation:
The second test Lee did was 13 points fewer than the first test, which was 91 points, so the second test's score is 91 - 13 = 78 points.
The third test had the score of 92, so this is the highest score, and the lowest score is the second one: 78 points.
The difference between Lee's highest and lowest scores is:
92 - 78 = 14 points
Answer:
The equation in the slope-intercept form will be:
Step-by-step explanation:
Given the points
Finding the slope between the points using the formula




We know that the point-slope of the line equation is

substituting
and (-39,49) in the equation


Now writing the equation in slope-intercept form

where m is the slope and b is the y-intercept






∵ 
Where
and the y-intercept i.e. 
Therefore, the equation in the slope-intercept form will be:
Answer:
x=8/7
2x times 7 divided by 2 = 8
solve for x
Answer:
x = 3
Step-by-step explanation:
3x + 2 = 11
subtract 2 from both sides
3x = 9
divide 3 on both sides
x = 3
