1/3 · (-3x + 4y - 5z) (1/3 Is A Fraction) (Write Explanation)

Mathematics

The value of expression is -(x- 4y/3 + 5z/3)

<h3>What is fraction?</h3>

A fraction represents a part of a whole or, more generally, any number of equal parts.

Given:

1/3 · (-3x + 4y - 5z)

= 1/3(-3x) + 1/3 *4y + 1/3* (-5z)

= -x +4/3*y -5/3 *z

=-(x- 4y/3 + 5z/3)

Hence, 1/3 · (-3x + 4y - 5z)= -(x- 4y/3 + 5z/3)

2.95 = 2 \frac{95}{100}
2 \frac{95}{100} = 2 \frac{19}{20} (simplifying)
2 \frac{19}{20} = \frac{59}{20} (times by the bottom and add the top)

How do I do this problem
Lena [83]

First you multiply 3 times x and 3 times 2 

4(3(x + 2) -1) =50

and get

4( 3x +6 -1) =50

then you add 6 plus -1

4 ( 3x +5) = 50

then multiply 4 times 3x and 4 times 5

12x +20 = 50 and subtract 20 from both sides

       -20    -20

and you will get

12x = 30

divided both sides by 12

12x/12 = 30/12

then you find the ones that are the same amount in decimals but are smaller

and that's your answer: x= 5/2


hope you get it!!!

Write a polynomial function that meets the stated conditions.The zeros are −1, 2, and 7.
kondaur [170]

Answer:

A polynomial function that meet the conditions is x³ - 8x² + 5x + 14 = 0

Step-by-step explanation:

Hi there!

Let´s start writting a generic factored function. In this case, the function has 3 zeros so that the factored form will have 3 terms:

(x + a)(x + b)(x + c) = 0

For this expression to be 0, either (x+a) = 0 or (x+b) = 0 or (x+c) = 0

Then:

x + a = 0 ⇒ x = -a

x + b = 0 ⇒ x = -b

x + c = 0 ⇒ x = -c

Then, the values "a", "b" and "c" are equal to the zeros of the function but with opposite sign. Then, in our case:

a = 1

b = -2

c = -7

Then, the polynomial fuction will be:

(x + 1)(x - 2)(x - 7) = 0

Apply distributive property:

(x² - 2x + x -2)(x -7) = 0

(x² - x - 2)(x - 7)

x³ - x² - 2x - 7x² + 7x + 14 = 0

x³ - 8x² + 5x + 14 = 0

Then, a polynomial function that meets the conditions is:

x³ - 8x² + 5x + 14 = 0

Have a nice day!

What is the solution to log 5 (x+30)= 3
Free_Kalibri [48]

Answer:

x = 95

Step-by-step explanation:

Using the rule of logarithms

• log_{b} x = n ⇔ x = b^{n}

Given

log_{5}(x + 30) = 3, then

x + 30 = 5³ = 125 ( subtract 30 from both sides )

x = 95
