Answer:

D: x < 20

Step-by-step explanation:

-4x + 16 > -64

subtract 16 from both sides because you must isolate x.

-4x + 16 - 16 > -64 - 16

-4x > -80

Then divide -4 on both sides... I believe that when you divide a number by a negative number you must flip the sign...

-4x/ -4 < -80/ -4

x < 20

(negative divided by a negative will result in a POSITIVE.)

Hope this helped... I truly apologize if this is wrong..

Answer:

The answer is below

Step-by-step explanation:

From the graph, we can see that both segment 1 and segment 2 are positive slopes (as the time increases, the number of people increases)

Segment 1 is more steep than segment 2 (the number of people increases in segment 1 more than segment 2). This means that the number of people entering the arena in segment 1 was higher than the rate of people entering the arena in segment 2.

Answer:

a.) x = 5.36

b.) y = - 0.001

c.) t = 11.26

d.) k = 4.57

Step-by-step explanation:

a) x−1.27=4.09

b) 2.3−y=2.301

c) t+3.04=14.3

d) 1.1+k=5.67

Solving. right?

a.) x = 4.09 + 1.27 = 5.36

b.) y = 2.3 - 2.301 = - 0.001

c.) t = 14.3 - 3.04 = 11.26

d.) k = 5.67 - 1.1 = 4.57
