7. Carlos is renovating a house and hires a plumber to install the piping for 4 points
the new bathroom. The plumber charges an initial fee plus an hourly rate
for the number of hours it will take to complete the installation. The
function y = 100 + 35x can be used to model the total cost of the job, in
dollars. What does the slope in the expression of this function represent? *
the initial fee for the installation, $35
the initial fee for the installation, $100
the cost per hour of installation work, $35
the number of hours to complete the installation, x

Answers

Answer 1

Answer:

the cost per hour of installation work, $35

Step-by-step explanation:

y = 35x + 100

the slope of a function is the coefficient of x, therefore, it is 35. $100 is the initial fee, since it ia the y intercept, and $35 is the cost per hour. y is the total amount, and x is the number of hours. Therefore, the only possible answer is the third choice,

What is the value of h(−2) when h(x)=3x+1?


Enter your answer in the box.

​h(−2)=​

Answers

Answer:

-5

Step-by-step explanation:

The answer is -5 because we have -2 as x. The function is h(x)=3x+1. 3 times -2=-6. When we add 1 to the result, we have -5 as the answer. Hope it helps!

The value of h(−2) when h(x)=3x+1 is h(-2) = -5

From the question,

The given function is h(x)=3x+1

To determine the value of h(-2), we will put x = -2 and evaluate

From

h(x)=3x+1

h(-2) becomes

h(-2)=3(-2) + 1

h(-2) = (3× -2) + 1

h(-2) = (-6) + 1

h(-2) = -6 + 1

h(-2) = -5

Hence, the value of h(−2) when h(x)=3x+1 is h(-2) = -5

Determine the 50th term in the sequence defined by an = -11+ 5(n − 1).

Answers

The 'nth' term is a formula with 'n' in it which enables you to find any term of a sequence without having to go up from one term to the next. 'n' stands for the term number so to find the 50th term we would just substitute 50 in the formula in place of 'n'.

Two laboratory technicians are running product quality tests. One technician takes 6 minutes less than the
other. What equation would give the amount of time, t, it would take to run the tests if the technicians work
together to split the work on the different tests?

Answers

Answer:

The time it will take will be ;

t = (2x -6)/(x^2-6x)

Where x is the amount of time

in minutes taken by the technician who is slower

Step-by-step explanation:

We want to write the time it would take to run the tests if the technicians work together.

Let the time taken by the first technician be x minutes

The time that would. taken by the second is 6 minutes less which is (x -6) minutes

So if they work together, how long will it take?

That would be ;

t = 1/x + 1/(x-6)

t = (x + x -6)/(x(x-6))

t = (2x -6)/(x^2 -6x)

The time it will take if they both work together is ;

t = (2x -6)/(x^2-6x)

where x minutes is the amount of time taken by the technician who is slower of the two

find the slope and the y intercept 2x+y-2=0

Answers

Answer:

Slope: -2; Y-intercept: 2

Step-by-step explanation:

To find the slope, you can rewrite the equation into standard form:

2x+y-2=0

2x+y=2

y=2-2x

The slope is the coefficient of x, which is -2. The y-intercept is the other number, which is 2.

Step-by-step explanation:

gradient= ‐2

y‐ik intercept=2

explanation: rearrange the equation to make y your subject

from the equation , you already know that ‐2 is m (from the equation y=mx +c , whereby m is your gradient) which means ‐2 is your gradient.

from your equation you would also know that 2 is your y‐intercept. also from the equation y=mx+c is your UK intercept

A line with a positive slope is parallel to one of the lines shown. What is its slope? Use the graph shown below.

Answers

The slope is 0.75 as 3/4 = 0.75

Answer:

Step-by-step explanation:

Only the blue line has a positive slope.  So the new line is parallel to the blue line.

Clearly, the blue line goes through the point (0, 3) (this is the y-intercept).  Follow this blue line upward and to the right until it intersects the horizontal line at the top of the diagram.  We must estimate the x-value of this point of intersection.  A good approximation would be 5 1/3.

Now estimate the slope of the blue line.  Starting at (0, 3), we move 5 1/3 units to the right (this is the "change in x," or "run")  We end up at (5 1/3, 3).  

Now, from the horizontal line y = 3 upward to the horizontal line at the very top of the graph, is 5 units.  This is the "rise."

Thus, the approximate value of the slope here is

                              5               5             15

m = rise / run = ---------- = -------------- = ----------- = m

                          5 1/3           16/3             16
