Mr. schwartz builds toy cars. he begins the week with a supply of 85 wheels, and uses 4 wheels for each car he builds. mr. schwartz plans to order more wheels once he has fewer than 40 wheels left. the inequality that can be used to find the number of cars, x, mr. schwartz builds before he places an order for more wheels is ? x < 40. mr. schwartz will need to order more wheels after building cars.

Mr.Schwartz begins the week with = 85 wheels

Number of wheels used per car = 4

He orders more wheels when less than 40 wheels are left.

Given inequality is = x<40

The minimum number of wheels he can use before ordering more wheels=

So, 45 minimum 45 wheels can be used before ordering more wheels.

4 wheels are used to make = 1 car

45 wheels are used to make = cars

If 12 cars are to be build then wheels required will be =

Beginning number of wheels = 85

Wheels used for making 12 cars = 48

Wheels left =

But as mentioned, Mr. Schwartz orders wheels if they are less than 40, so after building 12 cars, 37 wheels will be left and he will order more.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
