Determine the domain and range of the function F(x)=(x-3) {exponent of 2 behind the parentheses}

Answers

Answer 1

Answer: That's a parabola. Inside the parenthesis the x-3 affects the placement on the x axis. since is subtracting you move the vertex 3 to the right(because its backwards like that) There is no limit to the x, as it will slowly mom out forever even when its so steep that in reality you dont care, so domain is infinite or all real numbers. the parabola is positive so it moves up forever, but it never goes below its vertex on the x axis.
Domain=all real numbers
Range= all real numbers>or = 0

Ink cartridges weigh 1/8 pound. the total weight of the cartridges in a box is 4 1/2 pounds. how many cartridges does the box contain? show your work and explain why you chose the operation you did.

Answers

Answer: There are 36 cartridges that box contain.

Step-by-step explanation:

Since we have given that

Weight of ink cartridges = $(1)/(8)$ pounds

Total weight of the cartridges in a box = $4(1)/(2)=(9)/(2)\ pounds$

so, Number of cartridges that box contain is given by

$(9)/(2)/ (1)/(8)\n\n=(9)/(2)* (8)/(1)\n\n=9* 4\n\n=36$

Hence, there are 36 cartridges that box contain.

1/8x=4.5x (x is the number of cartridges)
Multiply both sides by 8
x=36
The box contains 36 cartridges.

I need help with this question.

Answers

Answer:

2 1/8 is located on the first line after 2 and 1 3/4 i think is located on the 3rd line after one

Step-by-step explanation:

3(x-1) - 8 = 4(1+x) +5. Too hard, i keep getting confused

Answers

3(x-1)-8=4(1+x)+5

One solution was found :

x = -20

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

3*(x-1)-8-(4*(1+x)+5)=0

Step by step solution :

Step 1 :

Equation at the end of step 1 :

((3•(x-1))-8)-(4•(x+1)+5) = 0

Step 2 :

Equation at the end of step 2 :

(3 • (x - 1) - 8) - (4x + 9) = 0

Step 3 :

Step 4 :

Pulling out like terms :

4.1 Pull out like factors :

-x - 20 = -1 • (x + 20)

Equation at the end of step 4 :

-x - 20 = 0

Step 5 :

Solving a Single Variable Equation :

5.1 Solve : -x-20 = 0

Add 20 to both sides of the equation :

-x = 20

Multiply both sides of the equation by (-1) : x = -20

One solution was found :

x = -20

I need to factor 5a^2 + 7a + 6b^2 - 4b but I can't figure it out.......could it possibly be prime?

Answers

I kind of forgot how to do it but here is what I know so far : first you separate the two parts into (5a^2 + 7a) + (6b^2-4b). This process is called grouping. Now you find the greatest common factor in both of them which later your equation will be a(5a + 7) +2b(3b - 2). That is all I can remember so hope that helped

Based on the graph, which inequality is correct for a number that is to the right of -3? A number line is shown from negative 8 to 8 at increments of 1. A circle is shown at negative 3. The entire portion of the number line to the right of negative 3 is shaded.

Answers

We have been given a number line graph. Using that graph, we have to identify about which inequality is correct for a number that is to the right of -

The entire portion of the number line to the right of negative 3 is shaded that means variable x must be greater than 3. So we may use x>3 or x>=3

A circle is shown at negative 3 which means 3 is not the part of answer so we will use x>3 not x>=3

Hence final answer is x>3

Answer:

I agree with the other person who put a answer it will not count the three so x>3 not x>-3
