Answer:
k = 8
Step-by-step explanation:
We know that 8(10-k) = 2k so:
8(10−k)=2k
<u>Simplify both sides of the equation:</u>
8(10−k)=2k
(8)(10)+(8)(−k)=2k
80+−8k=2k
−8k+80=2k
<u>Subtract 2k from both sides:</u>
−8k+80−2k=2k−2k
−10k+80=0
<u>Subtract 80 from both sides:</u>
−10k+80−80=0−80
−10k=−80
<u>Divide both sides by -10:</u>
k = 8

Answer:
Maya messed up on Step 1, David messed up on Step 2
Step-by-step explanation:
Maya:
Step 1 should distribute to 5x - 15 = 12
David:
Step 2 should be 3x - 2x = -2 - 3 after you combine like terms
Answer:
- y-intercept: 2000
- rate of change: 500
Step-by-step explanation:
When Timon starts, he is already $2000 in debt. If we represent Timon's debt with positive numbers, the y-intercept will be $2000.
Timon's debt seems to be increasing at the rate of $500 per month. That value is the rate of change.
After m months, Timon's debt d will be ...
d = 500m + 2000
Answer: If you take the square root of a number that is not a perfect square, it is going to be irrational. And then if you just take that irrational number and you multiply it, and you divide it by any other numbers, you're still going to get an irrational number. So square root of 8 is irrational. You divide that by 2, it is still irrational.
