The image below shows the graph of a sound recorded on an oscilloscope. what are the period and the amplitude? (each unit on the t-axis equals 0.01 seconds.) question 43 options: 0.025 seconds; 4.5 0.05 seconds; 4.5 0.025 seconds; 9 0.05 seconds; 9

answer: 7

step-by-step explanation: cause i checked it

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
