Alright! 

To simplify <em>4 + 6(7x + 7), </em>we must combine like terms. Right off the bat, we can see what we have to do thanks to the order of operations. 

<em>* original equation
</em><em>4 + 6(7x + 7)
</em>
<em>* alright, so - since we can't do anything in the parenthesis, we now have to see what we can do multiplication wise.
</em><em>4 + 42x + 42
</em>
<em>* alright, so we could multiply the two 7's by 6, but now what? well, we can't do anything else to the 42x because of the variable, so we have to now add 4 and 46!
</em><em>
</em><em>and our simplified equation is... 42x + 46! =)</em>

Find the domain of h(x)= 1/ 3x^2-15x
Schach [20]

Hello!

To find the domain of the function h(x), we need to find the values of x where it is undefined.

We can begin by factoring the denominator of the rational function, h(x).

h(x) = 1/(3x² - 15x) (factor 3x from the binomial)

h(x) = 1/3x(x - 5)

After factoring the denominator, apply the zero product property.

3x = 0 (divide both sides by 3)

x = 0

x - 5 = 0 (add 5 to both sides)

x = 5

The values of 0 and 5 cause h(x) to be undefined. The function h(x) comes from negative infinity to zero, where there is an asymptote. Also, from zero to five, there is also an asymptote. Finally, the function h(x) also goes to infinity from five.  

So therefore, the domain of the function h(x) is: (-∞, 0) ∪ (0, 5) ∪ (5, ∞).

The difference between two integers is 32.The ratio of these integers is 1:3.Find these integers​
shutvik [7]

Answer:

16 and 48

Step-by-step explanation:

let the 2 integers be x and 3x ← ratio 1 : 3

Then

3x - x = 32 ← difference between the integers

2x = 32 ( divide both sides by  2 )

x =  16

and 3x = 3 ×  16 =  48

Since magnitude of difference is 32

We can also express the difference as

x - 3x = 32

- 2x = 32 ( divide both sides by - 2 )

x = - 16

and 3x = 3 × - 16 = - 48

The 2 integers are 16 and 48 or - 16 and - 48

When number can each term of the equation be multiplied by to eliminate the fractions before solving 6-3/4x+1/3=1/2x+5​
PolarNik [594]

Answer:

12

Step-by-step explanation:

You need to find the least common denominator (LCD) to all the denominators of the fractions present in the equation. These denominators are (writing them in their prime factor form to make our calculations easier):

4=2^2\\3=3\\2=2

Therefore, we need to include a factor of 3, and two factors of 2 (2^2) in our least common denominator, so this LCD will be a perfectly divided by all three given denominators, therefore eliminating all fractions in the equation.

Our LCD is = 3*2^2=13*4=12
