(08.06A) The line of best fit for a scatter plot is shown below:

alexira [117]

Answer:

Step-by-step explanation:

lets pick 2 points on the line....(6,5) and (10,3)

slope = (y2 - y1) / (x2 - x1)

(6,5)....x1 = 6 and y1 = 5

(10,3)....x2 = 10 and y2 = 3

now we sub

slope = (3 - 5) / (10 - 6) = -2/4 = -1/2

now we use y = mx + b

slope(m) = -1/2

u can use either of ur points...I will use (6,5)...x = 6 and y = 5

now we sub and find b, the y int

5 = -1/2(6) + b

5 = -3 + b

5 + 3 = b

8 = b

so ur equation is : y = -1/2x + 8 <===

Ivanshal [37]

Answer: The number 12 represents admission charge in Mariana's equation.

Step-by-step explanation:

As per given ,

Total cost = ( Charge per ticket) (Number of tickets) + (Admission fees) (i)

For x = Number of tickets, the total cost (c) for a day at the amusement park is given as

$c = 1.50x + 12$ (ii)

Here, 12 = Admission fees [Comparing (i) and (ii)]

Hence, the number 12 represents admission charge in Mariana's equation.

12x - 5 = 8x - x + 50<br> Help please show work and check the solution

Inga [223]

Answer:

x = 11

Step-by-step explanation:

$12x - 5 = 8x - x + 50 \\ 12x - 5 = 7x + 50 \\ 12x - 5 - 7x = 7x + 50 - 7x \\ 12x - 7x - 5 = 50 \\ 5x - 5 = 50 \\ 5x - 5 + 5 = 50 + 5 \\ 5x = 55 \\ x = 11$

and check:

$12(11) - 5 = 8(11) - (11) + 50 \\ 132 - 5 = 77 + 50 \\ 127 = 127$
