Find rate of change=(y2-y1)/(x2-x1)
Rate of change=(70-30)/(2-1)=40
F (x)=40x
F (12)=40 (12)=980
-53 ≥ -3(3z + 3 ) + 3z
⇔ -53 ≥ -9z - 9 + 3z
⇔ -53 ≥ -6z - 9
⇔ -44 ≥ -6z
⇔ z ≥ 22/3
Answer:22. Plug in all the options and see if they are equal
Step-by-step explanation:
Like Terms : Terms with the same variable raised to the same power
Mean: Add all of the numbers together, then divide by how many numbers there are. So, your mean is 40.6 (Rounded to the nearest tenth)
Median: The middle number (when they are in order). So, your median is 44.
Mode: The mode is whatever number appears the most; however, since there are no repeating numbers, there is no mode for this data set.
Range: Range is the difference between the highest and lowest values of the data set. So, your range is 55.
