Answer:
y = 15 hour - 3 hours/day x days
y = 15 - 3x
y-intercept = 15 - 3(0)= 15 which is the amount of volunteer hours she must complete at day 0.
0 = 15 - 3x
3x = 15
x = 5 (Number of days she would have to volunteer)
Equation: y = 15- 3x
Step-by-step explanation:
Answer:
Option C is correct.
System of equation which will produce infinitely many solutions:
3x - y = 14
-9x +3y = -42
Step-by-step explanation:
From the options
Only equation which is infinitely many solutions is
3x - y = 14 ......[1]
-9x +3y = -42 ......[2]
For infinitely many solutions, we are looking for linearly dependent equations, which means one equation is an exact multiple or sub-multiple of the other.
Multiply [1] by -3 we get

or
-9x + 3y = -42 which is same equation as [2]
therefore. by definition of infinitely many solution,
equation 2 is -3 times(or multiple) of equation 1
For any event A, P(A does not occur) = 1-P(A)
