What is the slope of the line that passes through (-3,4) and (-3,-4)
suter [353]

Answer:

undefined

Step-by-step explanation:

We can use the slope formula to find the slope

m = ( y2-y1)/(x2-x1)

    = ( -4-4)/( -3 - -3)

   = ( -4-4)/( -3+3)

   = -8/0

When we divide by zero, the answer is undefined so the slope is undefined

If average of m numbers is n^2 and average of n numbers is m^2 then average of m+n numbers is 
kkurt [141]
The sum of the m numbers divided by m (which is the average) equals n^2. Then, the sum of the m numbers equals mn^2.
The sum of the n numbers divided by n (which is the average) equals m^2. Then, the sum of the n numbers equals nm^2.
The average of m+n numbers which is the sum of the m numbers plus the sum of the n numbers divided by (m+n) equals (mn^2+nm^2)/(m+n). This is mn(n+m)/(m+n). Then the factor (m+n) can be ruled out and the result is mn.

Write the mixed number as a percent <br><br> 2 41/50
ehidna [41]

Answer:

∴ 2 \frac{41}{50}  = 282 %

Step-by-step explanation:

2 \frac{41}{50}

= [( 2 × 50) + 41] ÷ 50

=  ( 100 + 41) ÷ 50

= \frac{141}{50}

=( \frac{141 }{50} ) × \frac{2}{2}

= \frac{282}{100}

= 282 %

∴ 2 \frac{41}{50}  = 282 %

On the second day of a hiking trip, the tourists covered 17% bigger distance than on the first day. By how many percent did thei
finlep [7]
Speed=distance/time
suppose the distance of the first day is d, and the time is t
distance of the second day: d+0.17d=1.17d
time of the second day: t+0.2t=1.2t
speed of the second day: 1.17d/1.2t=0.975(d/t)=(1-0.025)(d/t)
so the speed of the second day is 2.5% slower than the first day.
