Answer:

$v(-3)=23\\v(0)=14\\v(4)=2$

Step-by-step explanation:

$v(x)=14-3x$

$v(-3)=14-3(-3)\\\\v(-3)=14-(-9)\\\\v(-3)=23$

$v(0)=14-3(0)\\\\v(0)=14-0\\\\v(0)=14$

$v(4)=14-3(4)\\\\v(4)=14-12\\\\v(4)=2$

Answer:

$2 = v(4) \\ 14 = v(0) \\ 23 = v(-3)$

Step-by-step explanation:

$14 - 3(4) = 14 - 12 = 2 \\ 14 - 3(0) = 14 ± 0 = 14 \\ 14 - 3( -3) = 14 + 9 = 23$

Double negatives are ALWAYS positive, so be EXTREMELY careful on the first exercise.

Because it goes up for a constant rate, to find the rice for 1 hour of parking do 16.00-12.50 and get 3.50 . To find the fee, just subtract 12.5 - 3.5
The fee for parking is $9

Answer:

$x=2$ and $y=-1$

Step-by-step explanation:

If two equations are given, we can solve one of the equation in terms of single variable and put it in the other equation which will further give the value of x and y.

For the given equations:

$8x-5y=21$ Equation:1
