Answer:
y = -3x + 1
Step-by-step explanation:
Plug in your x (2) and y (-5) values into your slope-intercept formula (y=mx+b).
-5 = -3(2) +b
Solve for b:
-5 = -3(2) + b
-5 = -6 + b
1 = b
Plug in the value of <em>b, </em>and<em> </em>the slope (-3) for the formula:
y = -3x + 1
Answer:
A
Step-by-step explanation:
To convert degrees to radians
radian measure = degree measure ×
Hence
radian measure = 150° ×
Cancel both 150 and 180 by 30, then
radian measure = 5 × =
Answer:
21/5 or 4 1/5
Step-by-step explanation:
When you're trying to find an estimate, the best thing to do is to round them accordingly.
357.9 can be rounded to 360 (as it is over 5, therefore, it is rounded up)
21 can be rounded to 20 (as it is under 5, it is rounded down)
Then to find the miles per gallon, you need to divide the distance driven (360), by the amount of gas (20)
360/20= 18
As an estimate, Ellen gets 18 miles to the gallon.
(The actual answer is 357.9/21= 17.13 miles to the gallon)
Hope this helps :)
