Answer :

$38 + $2(n) where n is the no. of cars.

Step-by-step explanation:

He earns $38 daily which is fixed and additional $2 wage depends on the no. of cars which means no. of cars will determine how many $2's he earns.

25 cars = $38 + $2 (25) = $88

30 cars = $38 + $2 (30) = $98

35 cars = $38 + $2 (35) = $108

40 cars = $38 + $2 (40) = $118

The domain and range for the relation is [-∞, ∞]  and [0,-3], and both  of them can be described by interval notation .

Since the graph given to us present a relation or a function, The domain and range of a function are the set of all the inputs and yield a function that can grant separately. The domain and range are vital viewpoints of a function. The domain takes all the conceivable input values from the set of real numbers and the range takes all the yield values of the function. In simple words, the domain is the set of all "x" values and the range is the set of all "y" values in a set of ordered sets and the requested sets are composed as in the form (x, y) or [x,y]

for the given the points are : (0,-3),(1,-3),(2,-3),(3,-3),(4,-3),(5,-3),(-1,-3)(-2,-3),(-3,-3),(-4,-3),(-5,-3)

so the domain set is ={-5,-4,-3,-2,-1,0,1,2,3,4,5}

and the range set is ={0,-3,-4,-5,-6,-7,-8}

so the domain and range is [-∞, ∞] and [0,-3]

To know more about the range and domain refer to the linkhttps://brainly.com/question/28135761?referrer=searchResults.

Write an equation of a line parallel to y = 2x-4 passing through the point (-1,3)
polet [3.4K]

Answer:

Parallel lines have the same slope, so you know the equation will be y = 2x + b. Use the point (1,5) to sub in for (x,y) to solve for b. So, the equation will be y = 2x + 3.
