On the first day, there were ten notebooks sold and five pencils sold. On the second day, there were 25 notebooks sold and 10 pencils sold.
This is a linear function. If x=0, y=0; if x=2, y=4, etc. Plot the points given by these coordinate pairs: (0,0), (2,4), ....
The resulting graph is the straight line drawn thru these points. It has a slope of 2 and a y-intercept of 0.
If you meant y = 2^x, then you have an exponential function, which is an entirely different matter.
Answer: p/r= number of seats in one row
Step-by-step explanation:
Step-by-step explanation:
Based off of the fitted line, we obtain expected values, given an input. If the input is 0 minutes remaining (meaning a student turns in a test with no time remaining), the expected value of their exam score is 87.
3.5x-10>-3 add 10 to both sides
3.5x>13 divide both sides by 3.5
x>26/7
x=(26/7, +oo)
...
8x-9<39 add 9 to both sides
8x<48 divide both sides by 8
x<6
x=(-oo,6)
Since this is a compound inequality with AND the solution set will be the union of the two intervals found above.
x=(26/7, 6)
