Answer:
x = 
Step-by-step explanation:
3x+6 = 4x^2
4x^2 -3x -6 = 0
x = 
Y + 3 = x - 1
- 3 - 3
y = x - 4
The slope-intercept form of the equation of the line is y = x - 4.
Answer:
Adults = x
Students = y = x + 40. 40 more student than adult
Adult = $8, Student = $6
Total for Adults = 8*x = 8x
Total for students = 6*y = 6y
Total = $1920
8x + 6y = 1920
Hence system of equations are:
y = x + 40
8x + 6y = 1920
Answer:
$8.95
Step-by-step explanation:
8 + 6 + 7 = 21
$187.95 divided by 21 = $8.95
