A scatter plot was constructed and a line of best fit drawn as shown.
levacccp [35]

<u>Answer</u>

y = 5x +25


<u>Explanation</u>

To get the equation of a line, first get the slope of the line.

Slope = (change in y)/(change in x)

          = (60-30)/(7-1)

          = 30/6

            = 5

Now use one point in the line (4,45) and a general point (x,y).

Slope = (change in y)/(change in x)

    5 = (y - 45)/(x - 4)

    5(x - 4) = (y - 45)

  5x - 20 = y - 45

y = 5x -20 + 45

y = 5x + 25

Can somebody help me with this problem. And make sure that u can explain how to do it don't just give me the answer.
Tpy6a [65]

Answer:

x=50

Step-by-step explanation:

Look at the triangle as a whole. This is a 30-60-90 triangle by speculation. You can see that the hypotenuse is equal to 100. By using sine (you can use cosine as well) , you get the expression, "(sin 30 degrees) = x/100" since sin is the opposite side over the hypotenuse. Do some basic trigonometry to get "1/2 = x/100". By now, you should know that 50/100 is the same as 1/2.

Solve and graph the inequality:-12&gt;-k-(3k+4)
Ber [7]
Alright Fabian, here's the deal.

First you need to solve the inequality for k. To do this, you have to 
a) distribute the -(3k + 4)
b) collect like terms: -k - 3k 
c) move the term with k to the left (optional but it's a habit)
d) divide both sides by the coefficient. Check out picture for details.
