Answer:
y=-x-0.833.....
Step-by-step explanation:
You solve for Y in the first two and then solve for x in the last two parts of the problem.
Answer:
C
Step-by-step explanation:
We want a line of best fit, which means we want to create a line that the data points will lie closest to.
One thing we can do is find the slope between the bottom-leftmost point and the top-rightmost point. This is because if we were to draw a line connecting these two, it will cut through the data quite well.
Those two points are (9, 15) and (16, 18), so the slope is change in y divided by the change in x:
(18 - 15) ÷ (16 - 9) = 3 ÷ 7 ≈ 0.4
Eliminate A and B.
Now we need to determine the y-intercept. This needs no calculations; simply look at the graph: there's no way a line cutting through the y-intercept point of (0, 18) will perfectly match the data points; instead it must be a y-intercept lower than 18. So, eliminate D.
The answer is C.
Answer:
Step-by-step explanation:
A truck drove 229.77 miles on 11.1 gallons of gas.
<u>Find the mileage per gallon:</u>
<u>Find the distance can be driven on full tank:</u>
- 20.7 * 16.8 = 347.76 miles
When you divide something by 10, yo move the decimal place one place to the left so exg
20.0/10=2.0
so divide by 1000 means move the decimal place 3 places to the left so if you had 20,000.0/1000=20.0 so
6.82/1000=0.00682
