Answer:
<em>~ Jill needs a minimum score of 90% to recieve an average of at least 92% on all her math quizzes ~</em>
Step-by-step explanation:
1. The table shows that her past weeks math quiz scores are: 92, 96, 94, 88
2. If she were to get a mean, or average, of at least 92, we could set up an equation to determine the minimum score she will recieve on her next quiz:
92 + 96 + 94 + 88 + x/ 5 = 92 ⇒ <em>(where x is the minimum score she should recieve on her next quiz to get an average of at least 92%)</em>
3. Now let us solve this equation for x through simple algebra ⇒
92 + 96 + 94 + 88 + x/ 5 = 92 ⇒
370 + x/5 = 92 ⇒
x/5 + 74 = 92 ⇒
x/5 = 18
x = 90
4. <em>Jill needs a minimum score of 90% to recieve an average of at least 92% on all her math quizzes</em>
Acceleration = (v1-v0)/t = (30-50)/5=-20 mph/s
Additional time it takes to stop
=(0-30)/-20
=1.5 seconds
Total time = 5+1.5 =6.5 seconds.

Answer:
A linear function is a function with standard form y = mx + b, where m is the slope and b is the y-intercept, and whose graph looks like a straight line. There are other functions whose graph is not a straight line. These functions are known as nonlinear functions and they come in many different forms.
If it is a straight line it is linear and if it is not a straight line ot is non linear!
Hope this works!
