Answer & Step-by-step explanation:
Devin runs an average of 15 min in 7 days
15 * 7 = 105 minutes
She has a goal of running 10² min. in 7 days
10² = 100 minutes
Will she complete her running goal in 7 days?
Yes. On average, she will run 105 minutes in seven days which is more than her 100 minute goal.
That means that it has 2 complex roots, and it has no x intercepts, means that it doesn't touch the x axis at all
Since he must not exceed 8 hours driving in a day:
Let the distance of the picnic be = x km.
Therefore time for forward journey = x / 60
Return journey = x / 50
The total trip should not exceed 8 hours.
Therefore: x / 60 + x / 50 <= 8. LCM = 300
Taking LCM and multiplying on both sides:
5x + 6x <= 8(300)
11x <= 2400
x <= 2400/11
x <= 218.18
The picnic spot must be less than or equal to 218.18 km.
Answer:

Answer:
The point slope equation is: y - y1 = m (x - x1)
m = slope
Step-by-step explanation:
To use this equation, you need to know:
-<u> </u><u>one point on the line</u>
-<u> the slope of the line</u>
<u>First</u>:
(x1,y1) = a known point on the line
m = the slope
(x,y) = any other point on the line
<u>Now</u>:
we plug the numbers into the equation to get y - y1 = m (x - x1)
<u>Then</u>:
you solve the equation
