Part A
 The first thing we must do in this case is to hide the slopes of each line.
 line m:
 m = (- 4-3) / (0 - (- 4))
 m = -7 / 4
 Line n:
 n = (- 2-2) / (3-1)
 n = -4 / 2
 n = -2
 Answer:
 Lines m and n are not parallel because their slopes are different.

 Part B:
 
We look for the slope of the K line:
 k = (1 - (- 3)) / (4 - (- 3))
 k = 4/7
 We observe that it is true that:
 k = -1 / m
 Answer: 
 The lines are perpendicular.

Please help, will give brianlist.<br><br> 1. Solve the equation. Show all of your work.
siniylev [52]

x +  \frac{3}{7 }  =  \frac{5}{7}

\frac{7x + 3}{7}  =  \frac{5}{7}

(7x + 3) \times 7 = 5 \times 7

by cross multiplication.

49x + 21 = 35

49x = 35 - 21

49x = 14

x =  \frac{14}{49}

x =  \frac{2}{7}

Which quadratic regression equation best fits the data set?
nata0808 [166]

Answer: y = 1.87x^2 -5.16 x + 10.54

Step-by-step explanation:

Since the general quadratic equation is,

y = ax^2 + bx+c

Here the given table is,

x           1             2              3            4               5              6             7

y          5.9        8.9          13.4         20.1          30.1         45.1        67.7

By the graphing calculator,

a = 1.87024 ≈ 1.87

b= -5.15833 ≈ -5.15

c = 10.5429 ≈ 10.54

By putting the values of a, b and c,

The required quadratic equation is,

1.87 x^2 -5.15x + 10.54

⇒ First Option is correct.

<em>Greetings from Brasil...</em>

Here is the problem:

[(15X - 8)/3] + [(9X - 3)/2]

<em>Let's multiply everything by 6</em>

[6.(15X - 8)/3] + [6.(9X - 3)/2]

[2.(15X - 8)] + [3.(9X - 3)]

30X - 16 + 27X - 9

<h3>57X - 25</h3>
