Which of the following choices translates the sentence “the difference of three times a number and 20 is 13”?

The difference of three times a number and 20 = 13

2. The word difference signals subtraction.

3. The phrase a number sigals that the number is unknown, so a variable should be used. In this case, I'll use x.

The table shows the outputs, y, for different inputs, x:
ASHA 777 [7]
Part A:
Yes, the data represent a function because there is at least one x-value for every y-value.

Part B:
When x=6 in the input-output table, y=14. When x=6 in the relation f(x)=7x-15, f(x)=7(6)-15=27. <span>The equation has a greater value when x=6.

Part C:</span>
Set f(x) equal to 6 in the equation:
6=7x-15
Solve for x:
7x=21
x=3
<span>x=3 when f(x)=6</span>

Divide x^3/4 over x^1/6
kvv77 [185]

Answer:

A

Step-by-step explanation:

\frac{x^{\frac{3}{4} } }{x^{\frac{1}{6} } }  = x^{\frac{3}{4} - \frac{1}{6} \\

\frac{3}{4} - \frac{1}{6}  = \frac{(3 * 6) - (4 * 1)}{(4 * 6)}

\frac{18 - 4}{24}  = \frac{14}{24} = \frac{7}{12}
