Use the diagram that awnser the questions.
CaHeK987 [17]
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.

Solve the following inequality. 21&lt;_-3(x - 4) &lt; 30 A. 28&lt;_x &lt; 37 B. -3 &lt;_ x &lt; 6 C. -6 &lt; x &lt;_ -3 D. -10 &
Aloiza [94]

Answer:

Option C -6

Step-by-step explanation:

we have

21\leq -3(x-4)

The compound inequality can be divided into two inequality

21\leq -3(x-4) -----> inequality A

-3(x-4) ----> inequality B

Solve inequality A

21\leq -3x+12

9\leq -3x

Divide by -3 both sides

when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol

-3\geq x

Rewrite

x\leq -3

The solution of the inequality A is the interval (-∞,-3]

Solve the inequality B

-3x+12

-3x

Divide by -3 both sides

when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol

x>-6

The solution of the inequality B is the interval [-6,∞)

The solution of the compound inequality is

[-6,∞) ∩ (-∞,-3]=(-6,-3]

-6

Answer to:<br> (a - 3b)(2a - 5b)<br><br> distributive form
Alina [70]
When I look at a problem like this, I think of the FOIL method. This method states "You multiply integers in the order of First, Outside, Inside, Last, and then add them  together"

(a -3b)(2a - 5b)

First --- 2a * a
Out  --- (-5b) * a
In     --- (-3b) * 2a
Last --- (-3b) * (-5b)

2a² - 5ab -6ab + 15b²

2a² - ab + 15b²

This would be your answer in simplest form!

A straight line has an equation y= 4x=5 Write down the equation of the straight line that is parallel to y=4x-5 and passes throu
Eduardwww [97]


Parallel lines have same slope but different y-intercept. So they gave the equation y=4x-5 and the (0,3) where 3 is the y-intercept.


So the equation would be y=4x+3. HOPE THIS HELPS!!!!!!!!
