21 cars, 32 motorcycles.
create a system of equations using x for cars and y for motorcycles.
$\left \{ {{x+y=53} \atop {4x+2y=148}} \right.$
multiply the top equation by 2 to prepare for elimination method
$\left \{ {{2x+2y=106} \atop {4x+2y=148}} \right.$
subtract terms
$\left \{ {{2x+2y=106} \atop {-4x-2y=-148}} \right. = (-2x = -42)$
divide both sides by negative 2 to solve for x
x =21
plug in x into original equation to solve for y.
21 + y = 53
subtract both sides by 21
y=32

noname [10]

Answer:

Step-by-step explanation:

The graph can take any value of X

-3[ x^2 - 2x + 1] + 4

-3x^2 +6x -3 + 4

-3x^2 + 6x + 1

x can take any value of real numbers and there would be a solution

Hence all real numbers is the domain.
