Answer:
y = 12x - 37
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here m = 12, thus
y = 12x + c ← is the partial equation
To find c substitute (3, - 1) into the partial equation
- 1 = 36 + c ⇒ c = - 1 - 36 = - 37
y = 12x - 37 ← is the equation of the line

Answer:
62 minutes.
Step-by-step explanation:
To find the mean, you need to <u>add</u> together all of your values (the minutes) and <u>divide</u> them by the number of values (how many sets of minutes given).
So, choosing to add 62 minutes:
38 + 40 + 40 + 42 + 43 + 50 + 62 = 315
There are 7 sets of minutes in total, so we then divide 315 by 7.
315/7 = 45 minutes
Therefore, running 62 minutes on the seventh day would cause you to run a mean of 45 minutes per day for the week.
3x² - 8x > 11
3x² - 8x - 11 > 11 - 11
3x² - 8x - 11 > 0
x > <u>-(-8) +/- √((-8)² - 4(3)(-11))</u>
