Not sure what problem you mean, perhaps
4(3) + 4(6) = 4(3+6) = 4(9) = 36
Answer: 36
Answer:
20
Step-by-step explanation:
20 - 14= 6
6 * -3= -18
Answer:
Part A: Yes, there should be a strong negative correlation between number of hours of internet browsing and score on math test. Justification: By calculating the correlation coefficient it is about -1. This means there is a strong negative correlation. Part B:y=-2x+95 Part C: The slope indicates that scores on a math test decrease by two for every hour internet browsing. The y-intercept indicates the score you have when browsing 0 hours on the internet.

I hope this helps :D. I recommend getting a t-inspire calculator if you don't already have one. It can be so helpful when solving these types of problems.
Answer:
2
Step-by-step explanation:
Step-by-step explanation:
if you divide 0 by any number you will get 0!!!
if you will substitute x for 2 you will have:
2-2/2+2 = 0/4 = 0
This is a DRT (Distance, Rate, Time) problem. So, we can set up a table to get our answer. Our table should look something like this:
<u> </u>
<u>D R T</u><u>Slow Truck d-50 60 t</u>
<u>Fast Truck d 70 t</u>
Now that we have set up our table, we can use the values to find the answer. Starting off, we can use the rule T = D/R to get the equation

. Now, we can simply solve for d, which can be done by cross multiplying and simplifying. After we do that, we can get that d = 350. Then, we can use the formula T = D/R, as stated previously, to substitute the rate and distance, which gives us t = 350/70. Simplifying that, we can get t = 5. Therefore, the time it takes for the second truck to pass the first truck is
5 hours. Hope this helped and have a fabulous day!
