Your air conditioner hasn’t been working properly, so you decide to set up an appointment to have it fixed. The repair company tells you that it costs $99 for a one time service fee plus $50 every hour. The technician came to your house and determined the drain was clogged. The total bill came to $549. Write an equation that represents this situation. (do not use any spaces in your equation & use the letter "x" to represent your variable)

Answers

Answer:

[tex]99 + 50x = 549[/tex]

Alternatively you can write it as;

[tex]50x - 450 = 0[/tex]

Step-by-step explanation:

One time service fee=$99

Rate of service=$50/hour

let unknown hours=x

Therefore the equation is

[tex]99 + 50x = 549[/tex]

or you can further simplify it to:

[tex]50x - 450 = 0[/tex]

And you can then solve for x to be 9 hours.

7 students have 3 books each. Which helps you find the total number of books?

Answers

Answer:

21 Books in total

Step-by-step explanation:

If you just want the total number of books, here:

If each student has 3 books, and there are 7 students, we can create the equation: 7 * 3 :because this is showing that 7 people each have 3 books

7 * 3 = 21 so There are 21 books in total

Another we could write it is 3 + 3 + 3 + 3 + 3 + 3 + 3 because there are 7 students with 3 books each. Adding this up would equal 21.

Answer:

21 books in total

Step-by-step explanation:

If there is 7 students who have 3 books each, and want to find the total. The easiest way is multiply 7 with 3 to give you an answer of 21

Or draw a picture if it helps

Draw 7 stick figure and under it draw 3 books for them and count the books, still gives you 21

Use f(x)=-3/2x+11, g(x)=x^2-7x, and h(x)=|15-9x| to evaluate the function h(2/3)= ________

Answers

Answer:

The answer is nine

Step-by-step explanation:

The required solution of the the function is 9.

It is required to evaluate the function.

What is function?

A function is defined as a relation between a set of inputs having one output each. function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.

Given :

Now the given function is,

f(x)= -3/2x+11

g(x)=x^2-7x

h(x)=|15-9x|

To evaluate the function

h(2/3)

Put x = 2/3 in h(x) we get,

h(x) = |15 - 9(2/3)|

h(2/3)= |15 - 18/3|

h(2/3)= |15 - 6|

h(2/3)= |9|

h(2/3)= 9

Therefore, the required solution of the the function is 9.

Leslie ran a total of 8 miles over the course of 4 track practices. How many miles would Leslie have ran after 5 track practices? Solve using unit rate.

Answers

Answer:

10 miles

Step-by-step explanation:

Find how much she runs during one track practice by dividing 8 by 4. This gives you the equation 2x, with x being the number of track practices.

Answer: 10 miles after 5 track practices.

Step-by-step explanation: Lets find the unit rate of this problem. Remember that unit rate means the denominator will always have a 1.

8/4 converted to a unit rate is 2/1

The unit rate is 2 miles per every 1 track practice.

We can use the unit rate to solve how many miles Leslie would have ran after 5 track practices.

2/1 x 5 = 10/5

So, Leslie would have ran 10 miles after 5 track practices.

Two landscaping companies made bids on the landscaping of a new apartment complex. Company A bid $595,000 for materials and plants and $204,000 for labor. Company B bid $660,000 for materials and plants and $136,000 for labor. How much lower was the bid made by Company B?

Answers

Answer:

$3,000

Step-by-step explanation:

Company A bid $595,000 for materials and plants and $204,000 for labor.

Total = $595,000 + $204,000 = $799,000

Company B bid $660,000 for materials and plants and $136,000 for labor.

Total = $660,000 + $136,000 = $796,000

The difference:

$799,000 - $796,000 = $3,000

Which point-slope equation represents a line that passes through (3,-2) with a slope of -4/5
O y-3 =-4/5(x+2)
Oy - 2 =4/5(x-3)
Oy+2=-4/5(x-3)
O y + 3 = 4/5(x+2)

Answers

Step-by-step explanation:

To find an equation of a line in point slope form when given the slope and a point we use the formula

[tex]y - y_1 = m(x - x_1)[/tex]

where

m is the slope

( x1 , y1) is the point

From the question

the point is (3,-2) and slope - 4/5

The equation of the line is

[tex]y + 2 = - \frac{4}{5} (x - 3)[/tex]

Hope this helps you

The point-slope equation of the line is given by:

[tex]y + 2 = -\frac{4}{5}(x - 3)[/tex]

What is the point-slope equation of a line?

It is given by:

[tex]y - y_0 = m(x - x_0)[/tex].

In which:

m is the slope.[tex](x_0, y_0)[/tex] is the point.

The line that passes through (3,-2) with a slope of -4/5, hence the parameters are given by:

[tex]x_0 = 3, y_0 = -2, m = -\frac{4}{5}[/tex]

Thus, the equation of the line is:

[tex]y - y_0 = m(x - x_0)[/tex].

[tex]y - (-2) = -\frac{4}{5}(x - 3)[/tex].

[tex]y + 2 = -\frac{4}{5}(x - 3)[/tex]
