Check the picture below.

that's done just with the provided links, and I simply ran a line, so it'll be thereabouts, roughly between 13 and 14, depending on how you hang the line.

anyhow, if you have a TI(texas instruments) 89+ or higher, you can just provide the value pairs of the data and run a quadratic regression, or an exponential.

there are some online regression calculators as well.

Calculate the missing side length “x”.
Setler [38]

Answer: 1.68?

Step-by-step explanation:

i used trigonometry

Adjacent = cos 62 = A/30

cos 62 x 30 = 14 ( rounded off )

A = 14

X = A = cot 58 = A/14

cot 58 x 14 = 1.68

X = 1.68 ( rounded off )

What is the value of y when x = 6? -3x + 9y = 18
CaHeK987 [17]

Hey there! I'm happy to help!

Let's plug in our x value.

-3(6)+9y=18

-18+9y=18

We add 18 to both sides.

9y=36

We divide both sides by 9.

y=4

Have a wonderful day! :D

Suppose that a household's monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hu
olga nikolaevna [1]

Answer:

I hope that you are doing well, during this weird time; and that this message finds you in a good place.

To get you started on this problem, you will want to think about how to go about graphing this linear function. You want to keep in mind that you want to plot your dependent variable on the y-axis, as it changes with respect to your independent variable (plotted on the x-axis). In this problem, the cost of the water bill depends on the amount of water used, in HCF. So the graph should be plotted with cost on the y-axis, and HCF on the x-axis.

It follows that you are given the coordinates of (16, $48.37) and (22, y2); where y2 represents the cost when using 22 HCF. You are also given the slope of your line (m, in y = mx + b format). You may recall that you can set-up a slope as the change in y over the change in x, or the "rise over the run" [m = (y2-y1) / (x2-x1)]. We can set this problem up, using this equation to solve for y2 (the cost at 22 HCF) algebraically.

So we would set up the problem as 1.65 = (y2-48.37)/(22-16). We then solve by combining like-terms and using inverse operations as follows:  

  1.65 = (y2 - 48.37) / 6

  1.65(6) = y2 - 48.37

  9.9 = y2 - 48.37

  y2 = $58.27
