Answer:
x ≤ 3764.72
Step-by-step expl anation:
The Montanez family cannot use more than 7250.50 gallons, this means that they can use less than or equal to 7250.50 gallons, this tells you which sign to use. The variable x can be used to describe how much water they have left to use and then you add 3,485.78 gallons to x.
x + 3485.78 ≤ 7250.50 This inequality means that the amount of water the family has yet to use added to 3485.78 gallons cannot exceed 7250.50 gallons.
Next, you simplify the inequality using the property of inequalities.
x ≤ 7250.50 - 3485.78
x ≤ 3764.72
The required inequality is x<941.18 for the Montanez family if they have used 3485.78 gallons of water.
What is inequality?It is also a relationship between variables but this is in greater than , less than, greater than or equal to , less than or equal to is used.
How to form an inequality?Let the water used by a member be x
so
x*4=7250.50-3485.78
4x=3764.72
x=941.18
Hence one member can only use 941.18 gallons of water in the month.

Complete the solution of the equation. Find the value of y when x equals 1. 9x+7y=-12
Hey there! :)
Find the value of y when x=1 : 9x + 7y = -12
To find the value of y, simply plug in 1 for x in our given equation.
9(1) + 7y = -12
Simplify!
9 + 7y = -12
Subtract 9 from both sides so that we can isolate y.
7y = -12 - 9
Simplify.
7y = -21
Now, divide both sides by 7 to fully isolate y.
7y ÷ 7 = -21 ÷ 7
Simplify!

What is the domain of the function y=^3 sqrt x-1
Answer:
Domain is all real numbers also known as [tex](-\infty,\infty)[/tex] in interval notation.
[tex]f(x)=\sqrt[3]{x-1}[/tex]?
Step-by-step explanation:
If your function is [tex]f(x)=\sqrt[3]{x-1}[/tex] then the domain is all real numbers because you can cube root any real number.
If x is a real number, then x-1 is a real number.
So if you cube root (x-1) for any x then you still get a real number back.
Now if it was a square root, that is when we can run into some problems.

A triangle has two sides of lengths 7 and 9. What value could the length of the third side be?
Answer:
The length of the third side could be all real numbers greater than 2 units and less than 16 units
Step-by-step explanation:
we know that
The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.
so
Applying the triangle inequality theorem
Let
x ------> the length of the third side
we have
First case
1) 7+9 > x
16 > x
Rewrite
x< 16 units
Second case
2) 7+x > 9
x > 9-7
x > 2 units
therefore
The solution for the third side is the interval
(2,16)
All real numbers greater than 2 units and less than 16 units

Elise picks 6 pounds of apples.She uses 1/2 pounds to make 1 container of apple sauce. How many containers of applesauce can Elise make with all apples?
Answer:
12
Step-by-step explanation:
Mass of apples = number of containers × mass in each container
6 lb = No of containers × ½ lb
No of containers = 6/½
To divide a whole number by a fraction, invert the fraction and change divide to multiply.
6/½ = 6 × 2/1
Multiply the numerator by the whole number.
6 × 2/1 = 12/1
Simplify the fraction.
12/1 = 12
Elise can make 12 containers of applesauce.
7. Select True or False for each statement.
A. The ordered pair (2, -5.2) is located in Quadrant IV.
B. Quadrant Il contains ordered pairs of the form
(positive number, negative number)
C. The point (-6, 0) is located on the y-axis
D. The origin is located in Quadrant |
E. To plot points in Quadrant III, move left and down
From the origin.
The answer addresses the true or false nature of five statements about the properties of coordinate pairs in a two-dimensional graph with respect to their quadrants, and the location of specific points on the coordinate plane.
The coordinates (x, y) indicate the position of a point on a two-dimensional graph in relation to the origin, which is at (0, 0). In a standard coordinate system, Quadrant I has both x and y as positive, Quadrant II has x as negative and y as positive, Quadrant III has both x and y as negative, and Quadrant IV has x as positive and y as negative.
A. False - The ordered pair (2, -5.2) is located in Quadrant IV, which is incorrect since Quadrant IV should have x as positive and y as negative, which is actually the case here, so the statement should be True.B. False - Quadrant II contains ordered pairs of the form (negative number, positive number), not positive x and negative y.C. True - The point (-6, 0) located on the x-axis, not the y-axis, since the y-coordinate is zero.D. False - The origin (0, 0) is not located in any quadrant as it is the point of intersection of all the quadrants.E. True - To plot points in Quadrant III, one indeed moves left (negative x direction) and down (negative y direction) from the origin.Andy was playing a memory game with his sister. He turned over a tile to reveal a picture of the sun at the coordinates (5, 4). He looked under a tile that was 3 units to the left and 2 units down but revealed a picture of a tree. His sister knew that the other sun was 1 unit to the left and 1 unit up from the tree. What are the coordinates of the second sun? (JUSTIFY)
Answer:
(1, 3).
Step-by-step explanation:
The tree tiles coordinates are x = 5-3 = 2 and the y coordinate = 4 - 2 = 2
- that is (2, 2).
So the coordinates of the second sun are (2-1, 2 + 1)
= (1. 3).

CraftWork rents a storage space that measures 200 ft x 300 ft x 30 ft.
CraftWork pays $1500 for the storage space each month. What is the cost
per cubic foot?
O
A. $0.008
O B. $0.0002
O C. $0.0015
O D. 50.00083
Answer:
0.00083
Step-by-step explanation:
200*300*30=1800000
1500/1800000=0.00083
The cost per cubic foot of the storage space is approximately $0.00083 per cubic foot. Hence the correct option is D.
To find the cost per cubic foot of the storage space, we need to calculate the total cubic footage of the space and then divide the monthly cost by that number. The storage space measures 200 ft x 300 ft x 30 ft, so the total volume is:
Total Volume = length times width times height
= 200 ft x 300 ft x 30 ft
= 1,800,000 cubic feet
Now, we calculate the cost per cubic foot:
Cost Per Cubic Foot = Total Monthly Cost / Total Volume
= $1500 / 1,800,000 cubic feet
= $0.00083 per cubic foot (rounded to five decimal places).

what is the sum of the polynomials (-x^2+9)+(3x^2-11x+4)
The answer is:
[tex](-x^{2}+9)+(3x^2-11x+4)=2x^{2}-11x+13[/tex]
Why?To solve the problem, we must remember how to add/subtract like terms. The like terms are the terms that share the same variable and the same exponent.
For example:
[tex]2x+3x+x^{2}=x^{2}+(2x+3x)=x^{2}+5x[/tex]
We were able to add only the linear terms (terms that contains the variable x") because they were like terms: they share the same variable and the same exponent.
We need to perform the following operation between polynomials:
[tex](-x^{2}+9)+(3x^2-11x+4)[/tex]
So, calculating we have:
[tex](-x^{2}+9)+(3x^2-11x+4)=2x^{2}-11x+13[/tex]

Solve by factoring or finding square roots
x^2-1=0
Answer:
{1,-1}
Step-by-step explanation:
Let's do both!
Factoring!
x^2-1 is a difference of squares.
The formula for factoring a difference of squares is: u^2-v^2=(u-v)(u+v).
So the factored form of x^2-1 is (x-1)(x+1).
So we want to solve the equation x^2-1=0 which is equivalent to solving
(x-1)(x+1)=0.
If you have A*B=0 then either A=0 or B=0.
So in our case we have x-1=0 or x+1=0.
Now we just solve the equations.
x-1=0 can be solved by adding 1 on both sides giving us x=1.
x+1=0 can be solved by subtracting 1 on both sides giving us x=-1.
Square root!
When you want to use square roots, you have to have a perfect square containing the variables and a constant. We have that here.
We have x^2-1=0 which is equivalent to x^2=1. You could get this last equation by adding one on both sides of x^2-1=0.
Anyway, once you have the square part equals the constant, all you have to do is square root both sides to get rid of the square on the variable part.
[tex]x^2-1=0[/tex]
[tex]x^2=1[/tex]
[tex]\sqrt{x^2}=\sqrt{1}[/tex]
[tex]x=\pm \sqrt{1}[/tex] It leads to two answers because [tex]\sqrt{x^2}=|x|[/tex].
[tex]x=\pm 1[/tex]
The solution to the equation x^2-1=0 is x = 1 or x = -1.
Explanation:To solve the equation x^2-1=0 by factoring or finding square roots, we can start by rearranging the equation to get x^2=1. This means that the square of x is equal to 1. To find the square root of both sides, we take the square root of 1, which gives us x=±1. So the solution to the equation is x = 1 or x = -1.
