UI Now that you've created your hypotheses, it's time to prove them. First, look at the sum of two rational numbers. Let's say
they are two rational numbers, and y. Because theyre rational, they can be written as a ratio of integers. Letxe andy
4. where a, b, c, and d are integers and band d do not equalo. The process for finding the sum x + y in terms of a, b, c,
and d is shown,
Reason
Statement
x + y = f & 9
substitution
(5) () + (?) (5)
Croate common denominators,

Based on this sum and using the closure property of Integers, who conclusion can you make about the sum of two
rational numbers? Explain your answer.

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.

50- 250 is correct i did that one too

step-by-step explanation:

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x

=240

=48
