Step-by-step explanation:

{x}^{2}  + 7x + 10

{x}^{2}  + 5x + 2x + 10

x \times (x + 5) + 2(x + 5)

(x + 5) \times (x + 2)

What is the domain of f(x) = 3x – 2?
Elis [28]

Answer: las option.

Step-by-step explanation:

The equation of the line in slope-intercept form is:

y=mx+b

Where m is the slope of the line and b is the y-intercept.

Then function given in the problem has the form:

f(x)=3x-2

Where:

m=3

b=-2

Therefore, it is a linear function.

By definition, the domain of the  linear functions that are not bounded, is all the Real numbers.

Therefore, the answer is:

<em> {x | x is a real number}</em>

Farmer Bill sold potatoes at the farm market. He sold a quarter to the first person, 4/9 of what was left to the second person,
mel-nik [20]

Answer: 120 lb of potatoes.

Step-by-step explanation:

Let the pounds of potatoes sold by farmer Bill      = X lb

Fractional part sold to the first person                    = 1/4

Therefore 1/4 of X                                                      = 1/4  x X

                                                                                    = X/4 lb of potatoes.

No of potatoes left for sale                                        = X - X/4

                                                                                    = ( 4x - x )/4

                                                                                    = 3x/4 lb.

Fractional part sold to the second person out of the reminder = 4/9

Therefore 4/9 of 3x/4                                                 = 4/9 x 3x/4

                                                                                    = x/3 lb of potatoes.

Amount of potatoes left for sale                               = 3x/4 - x/3

Resolve into fraction , we have                                 = (9x - 4x)/12, because 12 is the LCM.

                                                                                    = 5x/12

Third buyer bought 4/5 of the left over                    = 4/5 of 5x/12

                                                                                   =   x/3 lb of potatoes.

Amount  of potatoes left                                           =   5x/12 - x/3

Resolve in to fraction again  taking 12 as the LCM =   ( 5x - 4x )/12

                                                                                   = x/12 lb of potatoes .

Therefore, the left over was 10 lb .

To determine the value of x now which correspond to the amount of potatoes sold by Farmer Bill, we shall the equate the left to  x/12 = 10                                                                                                                

we now cross multiply to get the value of x                             x = 120 lb.

therefore the pound of potatoes sold by farmer Bill  = 120 lb.

Choose the answer based on the most efficient method as presented in the lesson.
Grace [21]

Remember that to solve an equation we need to isolate the variable in one side. To do it we can perform any mathematical operations we want as long as we perform the operations to both sides of the equation.

Let's solve our equation step by step

Step 1. Subtract 2x from both sides of the equation

2x-8=5x+3

2x-2x-8=5x-2x+3

-8=3x+3

Step 2. Subtract 3 from both sides of the equation

-8-3=3x+3-3

-11=3x

Step 3. Divide both sides of the equation by 3

-11=3x

\frac{-11}{3} =\frac{3x}{3}

-\frac{11}{3} =x

x=-\frac{11}{3}

We can conclude that the next step is: subtract 3 from both sides of the equation.
