Answer:
g^-1 (x)=1/2x+3/2
Step-by-step explanation:
y=2x-3
x=2y-3
2y=x+3
y=1/2x+3/2
Answer:
-4
Step-by-step explanation:
-(-1) - (-2(-1) +3)
1 - (2+3)
1-5=-4
Answer:
3 1/3
Step-by-step explanation:
<u>Step 1</u> is to look at the problem.
Here, you notice that the first two numbers have fractions that are quarters. The total of those two fractions is 1/4 + 3/4 = 4/4 = 1.
So, the sum of the first two numbers is ...
1 1/4 + 3/4 = 1 +(1/4 +3/4) = 1 +1 = 2
<u>Step 2</u> is to add the next mixed number, which has a fraction with a different denominator. Since you have no fractions to add at this point, the sum is just ...
2 + 1 1/3 = 3 1/3

<em>Comment on adding fractions</em>
Generally, adding fractions requires you determine a common denominator. Often, you are asked to find the <em>least</em> common denominator, but that isn't necessary. Sometimes that can save the work of reducing the fraction that results, but sometimes it makes more work.
Here, a common denominator for fourths and thirds would be twelfths:
1/4 = 3/12
1/3 = 4/12
However, since adding the fourths results in an integer, no common denominator is necessary.
The conjecture or hypothesis given based on the attached graph is that there has been a general increase in the total loss of the Greenland Ice Sheet since 2007. However, since 2013, the rate at which the total loss increased began to decline.
<h3>What is a conjecture in math?</h3>
In mathematics, a hypothesis or a conjecture is a speculative conclusion or assertion that is stated without evidence.
<h3>How do you write a Conjecture ?</h3>
You must discover a trend or make some type of remark. For example, you may have observed that the list is increasing by twos.
You draw a conclusion based on the pattern you saw, just as you did when you determined that 18 would be the following number.
