Which inequalities have no solution
Nastasia [14]

<em><u>Answer:</u></em>

<em><u>Answer:If any of the inequalities in the compound OR inequality have a valid solution, the compound OR inequality will also have a valid solution. The inequality below has no solutions because x^2 + 1 is never less than 0 and -x^2 - x - 2 is never greater than 0.</u></em>

Select the equations of the lines that are parallel to the line whose equation is y= 3x +5.
Andru [333]

Answer:

-3x + y = 8.

3y = 9x.

Step-by-step explanation:

To find the slope of the lines we convert to slope-intercept form, which is

y = mx + c   (m is the slope.)

The slope of y = 3x + 5 is therefore 3.

Parallel lines have the same slope.

Finding the slope of the given lines:

-3x + y = 8

y = 3x + 8  - slope is 3 so this is parallel to  y = 3x + 5.

3y = 9x

Divide through by 3:

y = 3x  - so this is also parallel to 3x + 5.

y = -jx  The slope is -j so it is not parallel.

16x + 2y = 12

2y = -16x + 12

y = -8x + 6  - Not parallel.

Which situation can be represented by 80x &gt; 150 + 50x?
V125BC [204]

Answer:

All numbers greater than 5, i.e., x>5 .

Step-by-step explanation:

The given inequality is  

80x>150+50x

Isolate variable terms on one side to find the solution.

Subtract  50x from both sides.

80x-50x>150+50x-50x

30x>150

Divide both sides by 30.

\dfrac{30x}{30}>\dfrac{150}{30}

x>5

It means, all the numbers which are greater than 5, are the solutions of the given inequality and 5 is not included in the solution set.
