Answer:
x = 15
Step-by-step explanation:
Interior angles and their exterior angles make a supplementary angle meaning they have a sum of 180°. Knowing this, we can make an equation to solve for x.
x + 165 = 180
x = 15
Average rate=(change in y)/(change in x)
if f(x)=-x/3
r=( f(2)-f(-2) )/(2--2)
r=(-2/3-2/3)/(2+2)
r=(-4/3)/4
r=-4/12
r=-1/3
For a line, this is always true, since all lines have a constant velocity, the average velocity over any interval is equal to the slope.
Answer: 20 hours
Step-by-step explanation:
Since, One watch is slow and loses two minutes every hour
⇒ 1 hour of slow watch = 62 minutes
And, the other one is fast and gains one minute every hour.
⇒ 1 hour of fast watch = 59 minutes,
Hence, in 1 hour, the difference between slow and fast watch in 1 hour = 62 - 59 = 3 minutes.
⇒ The between slow and fast watch in 20 hours = 20 × 3 = 60 minutes or 1 hour.
Hence, after 20 hours the difference between the watches will be 1 hours.
Answer:
Assuming you combingin like terms
3x-6+3y
Answer:
Answer choices A, C, and D.
Step-by-step explanation:
If you assume that the 70 degrees is one of the base angles, then the other base angle is also 70 and the third angle is 40 degrees (thus answers C and D). However, if it is the top angle, the other two angles must both be 55 degrees (thus answer A). Hope this helps, and PM me with questions!
