The equations which represents the minimum and maximum scores of the students is; x = 87 ± 1.8.
<h3>Which equations represents the minimum and maximum possible scores of each student?</h3>
According to the task content, the
Average score of the students in the science class is; 87 points
All students are within 1.8 points of the average,
it therefore follows from the task content that the
minimum score is;
= 87 -1.8
= 85.2
maximum score is;
= 87+1.8
= 88.8 points.

Y = -2x - 2. Slope here is -2. A parallel line will have the same slope.
y = mx + b
slope(m) = -2
(3,4)...x = 3 and y = 4
now we sub and find b, the y int
4 = -2(3) + b
4 = - 6 + b
4 + 6 = b
10 = b
so ur parallel equation is : y = -2x + 10
If i read it right, it would just be 1 - 953. Depending on your grade (Around 3rd grade it would just be 952) Above that would be -952
<span><span>ab:ac=3:5
bd:cd=7:2
if cd is 5 cm then cd=2:5 then ab=3:x
2:5=3:x
15=2x
x=15/2
x=7.5 cm</span><span>
Happy studying! ^_^</span></span>
