It would be a, because some of the students could have really high income and some low, it’s very unpredictable, but all others will probably all be very close
Hope this helps!
Answer:
t=2
Step-by-step explanation:
log4(7t+2)=2
Raise each side to the base of 4
4^log4(7t+2)=4^2
The log goes away
7t+2 = 16
Subtract 2 from each side
7t+2-2 = 16-2
7t = 14
Divide each side by 7
7t/7 = 14/7
t = 2
Answer:just do 23 minus 6 and that should be the answer because the y-ccordinate is in the same place
Step-by-step explanation:
Answer:
x^3-4x^2+25x-100
Step-by-step explanation:
We have 2 roots -5i and 4. Using the conjugate root theorem for the root -5i, we know that 5i should be another root
Combining the roots into a polynomial gives us:
(x+5i)(x-5i)(x-4)
Expand:
(x^2 + 25)(x-4)
x^3-4x^2+25x-100
Answer:
x = 4, y = 2
Step-by-step explanation:
Start by multiplying the first equation by 2:
2x + 2y = 12 --> 4x + 4y = 24
Subtract the second from the first:
4x + 4y = 24
- 5x + 4y = 28
4x - 5x = -x
4y = 4y = 0
24 - 28 = -4
so you end with -x + 0 = -4
Solve for x to get x = 4
Plug x = 4 back into 2x + 2y = 12 to find y.
2(4) + 2y = 12
8 + 2y = 12
2y = 4
y = 2
