Answer:

14 - 9x + 12 + x

This is an <em>expression </em>(not an equation), therefore it can't be solved.

<u>Factor the expression</u>

Collect like terms:  

⇒ 14 + 12 - 9x + x

Combine like terms:  

⇒ -8x + 26

Find the highest common factor of 26 and 8

  • Factors of 26:  1, 2, 13, 26
  • Factors of 8:    1, 2, 4, 8

Therefore, the highest common factor is 2

Factor out -2 from -8x + 26:

⇒ -2(4x + 13)

Alternatively, factor out 2 from 26 - 8x:

⇒ 2(13 - 4x)

Answer:

5.   m < 1 = 72 degrees.

6.    m < 1 = 80 degrees.

Step-by-step explanation:

5. < 1 = 72 degrees.

If we draw a line through the point of < 1,  We see that  We have have 2 angles  of 40 and 32 ( alternate angles).

6.  By the same reasoning m < 1 = 60 + 20

= 80 degrees.

Directions: Solve <br> I think you cross multiply but I'm not really sure where to go from there.
Vlada [557]
I'm fairly sure they want you to cross multiply then graph. This will give you 'zeroes' which are solutions for x
if you graph (4x^3+3x^2)= z it'll give you a zero at -0.75 which means x= -3/4

In the graph shown below, if lines 1^1 are parallel, then the slope of the line 1^2 is?
Galina-37 [17]

Answer:

<h2>Two lines are parallel if the have the same slope. Example 1: Find the slope of the line parallel to the line 4x – 5y = 12. To find the slope of this line we need to get the line into slope-intercept form (y = mx + b), which means we need to solve for y: The slope of the line 4x – 5y = 12 is m = 4/5.</h2>
