Answer:

A. Subtraction Property of Equality

Step-by-step explanation:

3x + 4 = 10

Subtract 4 from both sides ---->Subtraction Property of Equality

3x + 4 - 4 = 10 - 4

3x = 6

If 3x + 4 = 10, then 3x = 6

3. Give an example of an expression with a rational exponent and explain how to convert it into radical form.

asambeis [7]

<h2>Solution -: </h2>

Example -1 

Here we have ,,, 

$(6 \: x) { \frac{9}{5} }^{}$

solve -; 

6x ^9×1/5

 $\big[(6x \: ) {}^{9} ] {}^{ \frac{1}{5} }$ 

Convert on radical form 

 $\sqrt[5]{(6x) {}^{9} }$ 

Example -2 

 $\displaystyle{}a {}^{ \frac{2}{5} } \\ = \sqrt[5]{x {}^{2} } \: \: \: \: \: \: \: \because ( \sqrt[m]{x {}^{n} } )$ 

<h2>__________________</h2><h3>More Basic Information -: </h3>

hair in the question 3x is called radicant and five is called the index of radical. and in second question X is radicant of the number and five and two are index of the number.

types of Radical -: 

pure radical
mixed radical
unequal radical
equal radical

rationalization 

the operation of multiplication of a radical with the other radical to get product a rational number is called rationalisation.

The ratio of rock songs to dance songs on Jonathan's MP3 player is 5:6. If Jonathan has between 100 and 120 rock and dance songs

Eddi Din [679]

So I estimated to 110. And I got 50 rock songs and 60 dance songs. I used the ratio 5:6. Hope this helps you.

Why might u want to estimate by rounding each value to the nearest $1 instead of to the nearest $5

Aleksandr [31]

You would want to round to the nearest $1 so that the total would be more accurate.

2 out of 4 statements supported the data above. This are:

JP Morgan Chase Tower has more height per story than the Key Tower.

- This is true. Comparing the height in ft, JP Morgan Chase has a height of 1,002 ft. It is higher than the Key tower which is 947 ft only.

The Key Tower has the least height per story.

- Looking at its height, this is the least. It only stands at 947 ft as compared to others that are more than 1,000 ft

Evaluate the function f(-2) - h(4) given the following functions: f(x) = 4x 2+ 9 h(x) = 3x - 14

Goryan [66]

Answer:

-86

Step-by-step explanation:

simplify each equation as much as possible

f(x)= 4x(2+9) add

4x(11) multiply

f(x)=44x

substitute given numbers into each equation

44(-2)=-88 3(4)-14= 12-14=-2

combine equations

-88-(-2)= -86 add since you are subtracting a negative number
