Answer:
The correct answer is D.
Step-by-step explanation:
When dividing -4 on both sides, the correct result becomes 8 is greater than or equal to <em>z</em><em>.</em><em> </em>This also means that the result of <em>z</em><em> </em>must be less than or equal to 8, so the graph also represents a closed point at 8 with the ray pointing towards the left with each result less than 8.
ANSWER
EXPLANATION
The given equation is
We square both sides of the equation to obtain,
This implies that,
Rewrite in standard quadratic equation form.
Factor
This implies that,
We check for extraneous solution by substituting each x-value into the original equation.
When x=-1,
2=-2....False
Hence x=-1 is an extraneous solution.
When x=6,
5=5 is True.
Hence x=6 is the only solution.
Parallel lines have the same slope. So in point slope form:
(y-2)=-3(x-1)
y=-3x+3+2
y=-3x+5
Answer A
Answer:
Zero
Step-by-step explanation:
2+6=8 which means it can't be. It has to be a length higher than 10
Answer:
26
Step-by-step explanation:
Given that:
At time, t=0, Billy puts 625 into an account paying 6% simple interest
At the end of year 2, George puts 400 into an account paying interest at a force of interest, 1/(6+t), for all t ≥ 2.
If both accounts continue to earn interest indefinitely at the levels given above, the amounts in both accounts will be equal at the end of year n. Calculate n.
In order to calculate n;
Let K constant to be the value of time for both accounts
At time, t=0, the value of time K when Billy puts 625 into an account paying 6% simple interest is:
At year end 2; George amount of 400 will grow at a force interest, then the value of
Therefore:
If K = K
Then:
625 + 37.5 = 300 +50 K
625-300 = 50 K - 37.5 K
325 = 12.5K
K = 325/12.5
K = 26
the amounts in both accounts at the end of year n = K = 26
