8x-4+6x+15

8x+6x-4+15

14x+11

Answer:

14x +11

Step-by-step explanation:

4(2x-1)+3(2x+5)=8x-4+6x+15

=14x+11

answer

8/25

Step-by-step explanation:

so you would keep the first fraction (2/15) then you would change the symbol then you would flip the other fraction (5/12). then you would multiply 2*12=24 and 15*5=75. then you would simplifie it. it would be 8/25.

Answer:

7x+14 I think is correct. it's just combining like terms

Answer:

x = ⅘

Step-by-step explanation:

For clarity, exponents should be marked with a ^.  25x² can be written as 25x^2.

25x² = 16

divide both sides by the 25

x² = 16/25

take the square root of both sides

x = √(16/25) = √16/√25 = 4/5

Answer:

$17

Step-by-step explanation:

This is simply stated as a function.

We can rewrite this problem out as --> f(d) = -d + 42

If we simply say that he spent d, the problem states that d is equivalent to 25.

So the function looks like this --> f(d) = -25 + 42

Therefore your answer becomes --> f(d) = 17

Answer:

Pounds of topsoil needs to order to cover an area of 169 square feet is 0.1275

Step-by-step explanation:

GIVEN: relation between the pounds of topsoil and area covered is ( a = 1325 p )

a represent area and b represent pounds of topsoil

To Find : pounds of topsoil needs to order to cover given area .

Solution : since here relation is given

                     a = 1325 p

            value of a = 169 square feet

so putting the value of a in above relation

       so ,  169 = 1325 p

             p = 169 / 1325  = 0.1275

So , pounds of topsoil needs to order to cover given area is 0.1275

Answer:

0.1275

The domain values of a rational function are not only restricted to the only set of all real numbers making the given statement false

The domain of a function is the input values of the function for which it exists.

Rational functions are function that can be written as a ratio of two functions. For example given the function f(x) = 2/x-3

The domain values are the input values x. The values of x can be any values either real numbers, integers, or even natural numbers.

This means that the domain values of a rational function are not only restricted to the only set of all real numbers making the given statement false

m = 4+n

Step-by-step explanation:

Given the expression 4 = m-n, we are to make m the subject of the formula

From the equation

4 = m-n

Rearrange

m-n = 4

Add n both sides of the equation

m-n+n = 4+n

m+0 =4+n

m = 4+n

Hence the expression for m is given as m = 4+n
