natulia [17]

Answer:

x > -11  

Step-by-step explanation:  

<u>Step 1:  Subtract 6 from both sides</u>  

-4x + 6 - 6 < 50 - 6  

-4x < 44

<u>Step 2:  Divide both sides by -4</u>  

-4x / -4 < 44 / -4

If you divide by a negative number, you flip the sign.  

<em>x > -11</em>

Answer: velocity-time graph

Step-by-step explanation: The principle is that the slope of the line on a velocity-time graph reveals useful information about the acceleration of the object. If the acceleration is zero, then the slope is zero (i.e., a horizontal line). If the acceleration is positive, then the slope is positive (i.e., an upward sloping line).
