This is an easy trinomial. You need to find two numbers that add up to -6 and multiply together to equal 8. Those numbers are -2 and -4. It would simplify to (b-2)(b-4)
Answer:
1 = B
2 = A
3 = C
4 = D
Step-by-step explanation:
Answer : (-∞,-1) U (-1, 1)
We need to find the interval(s) over which the function is increasing
We look at the intervals of x where the graph is increasing
Increasing interval of the graph is the part where the graph goes up.
At first the graph starts increasing and it increases till x=-1
So the first increasing interval is -infinity to -1 . We write it as (-∞,1)
Now, we look at the part where the graph changes direction
In the middle inverted U shaped graph , the graph starts increasing at x=-1 and increases till it changes direction. The graph is increasing till x=1
so second increasing interval is x=-1 to 1. we write it as (-1,1)
Now combine both intervals by a 'U' union
(-∞,-1) U (-1, 1)
First, add 84 to both sides, to isolate the exponential function.
Then, take the logarithm of both sides:
(2x+3)*log 5 = log 84
Solving for 2x+3, we get log 84 - log 5, and so
2x = -3 + log 84 - log 5. Dividing both sides by -3, we obtain the final answer:
-3 + log 84 - log 5
x = -----------------------------

Is this how it wrote the discount? Because if so, it would be 7% off of the original price. Then you'd get a grand total and answer of:
