Step-by-step explanation:
y — yı = m(x – xı) equation of a line
Points A(1,3) and B(2,1)
Slope (m) = (y2 – y1) / (x2 – x1)
(1 –3) / (2 – 1)
–2/1
–2
Thus, y –3 = –2 (x – 1)
y – 3 = –2x + 2
y –3 + 3 = –2x + 2 + 3
y = –2x + 5
Hi there! For this question, we will have to divide. When it comes to dividing fractions, we keep, change, flip. In other words, keep the first fraction the same, change division into multiplication, and flip the second fraction over by its reciprocal. In this case, 3/5 stays the same and 6/1 becomes 1/6. 3/5 * 1/6 is 3/10 or 1/10 in simplest form. There. There are 1/10 gallon of juice in each glass.

Why?
The first thing we need to do is find the area of the triangle, we can to that by subtracting the area of ABCD from ACBE, then, we can use the formulas to calculate the area for both triangle and rectangle to find "f" and "g".
Calculating we have:

Now, we can calculate "f" by using the formula to calculate the area of the triangle:

Now, finding "g" by using the formula to calculate the area of the rectangle, we have:

Hence, we have that:

Have a nice day!
The answer is 10% if There is 40% six graders and 20% seventh graders then you need 10% more to make 100% so it’s 10% eighth graders
