Answer:
d^6 - 18d^5 + 135d^4 - 540d^3 + 1215d^2 - 1458d + 729
Step-by-step explanation:
So, what you need to do is take away the parenthesis so you can combine like terms:
c+4-3c-2=0
Add 4 and -2: 4+-2=2
Add c and -3c: c+=3c=-2c
Now you have:
2-2c=0
Add the -2c to the other side so we can work on getting c alone:
2=2c
Divide by 2 so c will now be alone:
c=1
The answer is C
Hope this helps :)
Answer:
Its the last option
y = 1488.33x + 23800 ; $172,600.
Step-by-step explanation:
The slope of the trend line = (median value for 2000 - median value for 1940) / 60
= 89300 / 60
= 1488.33.
So the equation is 1488.33x + 23,800
Estimate for 2040
is 1483.33* 100 + 23800
= 172,600.
Answer:
(3,8)
Step-by-step explanation:
y - 5 = x
4x - y = 4
Since y-5 = x, substitute y-5 in place of x in the second equation:
4x- y = 4
4(y-5) - y = 4
4y - 4*5 - y = 4
3y - 20 = 4
3y = 24
y =8
Solve for x:
y - 5 = x
8-5 = x
3 = x
Check:
4x - y = 4
4(3) - 8 = 4
12 - 8 = 4
4 = 4
Check
y - 5 = x
8 - 5 = 3
3 = 3
Check!
