Y = 4
y intercept is 4
The line would be horizontal and it would intersect the y axis at the point (0,4)
First off, let's convert the percentages to decimal format, so our 77% turns to 77/100 or 0.77, and our 55% turns to 55/100 or 0.55 and so on
now, the sum of both salines, must add up to the 77% mixture, let's say is "y"
so, 11 + 4 = y, and whatever the concentration level is, must also sum up to the mixture's concentration of 77%
anyway thus

solve for "x"
Answer:
9 students
Step-by-step explanation:
because 15x 3 = 45 so 12x3= 36 so 45-36= 9 Can i be branliest
