Answer. D) -1.9 and 2.6 are the solutions because when x=-1.9 and x=2.6 we have two points where the graph are cut. That is to say we have the same points in both graphs.
The initial amount of the money is £11,000 and the interest is 3.9% per year for first 3 years and then 4.5% after that. If Dan invests it for 7 years, that means the interest would be 3 years of 3.9% and 4 years of 4.5%.
The calculation would be:
total money= initial amount * interestrate1 * interest 2
total money= £11000 *(100%+3.9%)^3<span>*(100%+4.5%)^4
</span>total money= £11000 *(103.9%)^3 * (104.5%)^4
total money= £11000 * <span>1.121622319 </span>* 1.1925186
total money= £14,713.11
In -3,-1,0,3 is -3 and 3 pair of numbers has a sum of 0.
To find the possible pair of integers in each section, we apply the notion of integers. If it's possible, choose any two variables from a set of numbers and look for relationships between them.
Positive and negative counting numbers, as well as zero, make up integers. Think about each pair of integers or numbers whose sum will be zero. Discover this particular pair. There are numerous ways to obtain two integers whose total is zero. However, the number must match the opposing sign exactly.
Given numbers are -3,-1,0,3
From the given sum of the numbers, -3 and 3 are zero.
-3+3=0
