Amanufacturing machine has two processes. one of them is repeated 4 times and the second only once. the entire cycle can take no longer than 3 minutes. which graph represents this scenario?

The graph in the attached figure

Step-by-step explanation:

Let

x -----> time of the first process in minutes

y -----> time of the second process in minutes

we know that

The time of the first process multiplied by 4 (because is repeated 4 times) plus the time of the second process multiplied by 1 (because is repeated only once) must be less than or equal to 3 minutes

so

The inequality that represent this situation is

The solution of the inequality is the shaded area below the solid line

The equation of the solid line is

The y-intercept of the solid line is the point (0,3)

The x-intercept of the solid line is the point (0.75,0)

The slope of the solid line is negative m=-4

using a graphing tool

The solution is the shaded area

The graph in the attached figure

Remember that the time cannot be a negative number

The inequality represents the situation is:

And the graph is attached in the solution.

Step-by-step explanation:

Given information:

Time of first process in minutes

Time of second process in minutes

As we know that ,

according to the given information in the question we can write:

the inequality represents the situation is:

Here, the y-intercept of the solid line is the point (0,3)

And the x-intercept of the solid line is the point (0.75,0)

And the slope is negative

Now the graph of the above inequality can be formed as attached in the solution:

9

step-by-step explanation:

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
