Suppose that a household's monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hu

ndreds of cubic feet, HCF). When graphed, the function gives a line with a slope of 1.35 . See the figure below.
If the monthly cost for13 HCF is 25.43$ , what is the monthly cost for 19 HCF?

Given:
y = mx + b

m = slope
b = y-intercept.

m = 1.35

x = 13

25.43 = 1.35(13) + b
25.43 = 17.55 + b
b = 25.43 - 17.55
b = 7.88

y = 1.35(19) + 7.88
y = 25.65 + 7.88
y = 33.53

The monthly cost for 19HCF is $33.53

What is the sum of the arithmetic series 18 t=1 (3t-4)
PolarNik [594]

Consider the arithmetic series _{t=1}\Sigma^{t=18} (3t-4)

Let t=1 in the given series, we get

first term = a_{1} = 3-4 = -1.

Let t=2 in the given series, we get

second term = a_{2} = (3 \times 2)-4 = 2

Let t=3 in the given series, we get

third term = a_{3} = (3 \times 3)-4=5

Now, let t=18 in the given series, we get

last term = l = l = (3 \times 18)-4 = 50

We get the series as

-1, 2, 5,..... 50

Sum = \frac{n}{2}(a+l)

= \frac{18}{2}(-1+50)

= = 9 \times 49

= 441

Therefore, the sum of the given arithmetic series is 441.

Why is thinking about the problem before you work important?​
777dan777 [17]

Answer: It's good to think about things before doing them because it is more thought out and you have a better chance of getting things correct whereas without thinking your most likely going to get it wrong. Without thinking through your options you are basically guessing the answer. I hope this helped you have a great day and god bless you :D

When a system of linear equations is graphed, how is the graph of each equation related to the solutions of that equation?​
Kay [80]

Answer:

The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect.

State is a given functions are inverses. NO LINKS!! Part 2<br><br>​
nadya68 [22]

Step-by-step explanation:

5.

g(x)=-2x+1

let y=2x+1

Interchanging role of x & y

x=2y+1

y=½x-½

g-¹(x)=½(x-1)

not

equal to f(x)=-x+1

<u>Given function are not function of each other</u> .

6.

g(x)=-x

let

y=-x

Interchanging role of x & y

x=-y

y=-x

g-¹(x)=-x

not

equal to f(x)=3+⅓x

<u>Given function are not function of each other .</u>
