Answer:
C is a function... all the others are not functions since it doesn't pass the line test.
Step-by-step explanation:
5.625
Explanation:
y= what? Whats the first equation
First isolate y
3x + 2y = 14
-3x -3x
2y = -3x + 14
y = -3/2x + 14/2
y = -3/2x + 7
X-intercept is found when y = 0
0 = -3/2x + 7
-7 = -3/2x
x = 14/3
x-in. = (14/3,0)
1. 5n + 10d = 90
2. (18,0)
3. (0,9)
