How can complex fractions be used to solve problems involving ratios

Mathematics
1 answer:
strojnjashka [21]4 years ago
5 0
When you have ratios, and some unknowns, you can create complex fractions from them. Bring them to the same denominator, and solve for x.

Example - we have this proportion:
2-x
5-45
And we can change it into fraction:
\frac{2}{5}=\frac{x}{45}

\frac{2*9}{5*9}=\frac{x}{45}

\frac{18}{45}=\frac{x}{45}
18=x

In case of more complex fractions it may come in handy.

How is the graph of y=9(3)^x-2 -6 translated from the graph of y=9(3)^x ?
USPshnik [31]
For this case we have the following function:
 y = 9 (3) ^ x
 Applying the following transformations we have:
 Horizontal translations
 Suppose that h> 0
 To graph y = f (x-h), move the graph of h units to the right.
 y = 9 (3) ^ (x-2)
 Vertical translations
 Suppose that k> 0
 To graph y = f (x) -k, move the graph of k units down.
 y = 9 (3) ^ (x-2) - 6
 Answer:
 
2 units to the right
 
6 units down

Identify the missing symbol. 6/5 ? 1 1/5
pshichka [43]

Hello from MrBillDoesMath!

Answer:

=   (the equal sign)


Discussion:

Note sure if this is what they wanted but 6/5 = 1 1/5 so I'd guess the symbol is "=".  That is,

6/5 = 1 1/5


Thank you,

MrB

Which conditional statement has the same truth value as its converse
hodyreva [135]
In other words, you are looking for which one is the biconditional statement. 

A: This is true. Both the Conditional and Converse Statements are true. The Biconditional Statement would be this: The angles are bisected if and only if the angles have two congruent parts. This is true.

B: This is false. It is true as a conditional statement, but if you flip the p and q, it says that ALL acute angles are 60 degrees. This isn't true because a 35 degree angle or a 89 degree angle is also acute.

C: This is False. The conditional statement isn't true. The Converse statement is true but because the conditional statement is not then it is false. You can have two angles the aren't touching and they would be supplementary.

D:  This is False. The Conditional Statement is True but the converse is not. Not all congruent angles are vertical angles. You can have two angles that equal 90 degrees that form a line (supplementary) but they aren't vertical angles.

Therefore, your answer is A.

The relation R is shown below as a list of ordered
Dmitrij [34]

Answer:

(1, 4) and (1,3), because they have the same x-value

Step-by-step explanation:

For a relation to be regarded as a function, there should be no two y-values assigned to an x-value. However, two different x-values can have the same y-values.

In the relation given in the equation, the ordered pairs (1,4) and (1,3), prevent the relation from being a function because, two y-values were assigned to the same x-value. x = 1, is having y = 4, and 3 respectively.

Therefore, the relation is not a function anymore if both ordered pairs are included.

<em>The ordered pairs which make the relation not to be a function are: "(1, 4) and (1,3), because they have the same x-value".</em>
