Simplify
(d - 10) to
:
\frac{2(d - 10)}{5} [/tex] - 23(d + 6) x 25(d - 10) - 23(d + 6)
Simplify 23(d + 6) x 25(d - 10) to 575(d + 6)(d - 10) :
\frac{2(d - 10)}{5} [/tex] - 575(d + 6)(d - 10) - 23(d + 6)
Then Expand :
\frac{2(d - 10)}{5} [/tex] - 575
+ 5750d - 3450d + 34500 - 23d - 138
Now Collect Like Terms :
\frac{2(d - 10)}{5} [/tex] - 575
+ (5750d - 3450d + 34500 - 23d) + (34500 - 138)
Answer :
\frac{2(d - 10)}{5} [/tex] - 575
+ 2277d + 34362

The coordinates of D are (-3, -7)
First we need to find the coordinates of B. In order to do that we simply take the average of the two points that make up the segment for which it is the midpoint (A and C).
Average of x's
-9 + -1 = -10/2 = -5
Average of y's
-4 + 6 = 2/2 = 1
Therefore, the coordinates of B are (-5, 1).
Now we can find D by noting the E will be the average of B and D. So we can use the average equation to determine the values of D.
Average of x's
(B + D)/2 = E
(-5 + D)/2 = -4
-5 + D = -8
D = -3
Average of y's
(B + D)/2 = E
(1 + D)/2 = -3
1 + D = -6
D = -7
Now we know the coordinates of D to be (-3, -7)
Answer:
A - 18.5%
Step-by-step explanation:
1. subtract 6.75 from 8.00 = 1.25
2. multiply 6.75 by 18.5% = 1.25
Answer: 1
Step-by-step explanation: if a=2 then it would be 2 x 2 which is 4 and the minus 3 which is 1
Answer:
D
Step-by-step explanation:
Since we start with 10,080 gallons after 0 minutes pass, we see the next point. Luckily, we are given an exact point of a number between 10,080 and 8640. The difference of those two numbers is 1440, and divide that by 2 to get 720. So we drain 720 per hour. HOWEVER, it says "minutes", so we divide 720 by 60 (hour -> minutes) to get 12.
*The reason I divided by 2 was to get the number of gallons after 1 hour passes*
