write an absolute value equation that has the given solutions x=--10 and x=4
The suggested answers to the absolute value problem l x - 13 l = 7.
Except for 0, the absolute value is represented by a positive integer. In a variety of mathematical and physical situations, the notions of magnitude, distance, and norm are intimately related to the concept of absolute value.
In order to do this on a budget, find a number N that:
N-10=-(N + 4)
When we isolate N, we obtain:
2N= 10-4= 6
N= 6/2= 3
Following that, N-10= 3-10=-13, and N + 4= 3 + 4= 7.
as well as the fact that I-13I= I7I.
We can now express our equation as follows:
l x-13 l =7
As a result, where the roots (or solutions) of x = -10 and x = 4 are.

you are working on an air conditioning system. A roll of cylindrical copper tubing has an outside diameter of 7/8 inch and an inside diameter of 3/4 inch. How much refrierant can 12 feet of the tubing hold?
The amount of refrierant the tubing can hold is 0.037 cubic feet..
How much refrierant can the tubing hold?A cylinder is a three-dimensional object that is made up of a prism with a circular base. In order to determine how much refrigerant that cylindrical coil can hold, the volume of the cylinder has to be determined.
First, the dimension of the inside diameter has to be changed to feet
1 inch = 1/12 feet
3/4 x 1/12 = 1/16 feet
Volume of a cylinder = πr²h
Where:
π = pi = 22/ 7r = radius = diameter / 2 = 1 /16 ÷ 2 = 1 /16 x 1/2 = 1/32h = heightVolume = 22/7 x (1/32)² x 12 = 0.037 cubic feet.

Line h passes through point (3,0) and is perpendicular to the graph of y=1/5x-19. Line g is parallel to line h and passes through point (-1.15). What is the equation in slope intercept form of line g?
Answer:
y = -5x + 10
Step-by-step explanation:
Answer:
-5x + 10
Step-by-step explanation:
If a line 2 is perpendicular to line 1 and line 1 has slope m, then line 2 must have slope = [tex]\sf -\dfrac{1}{m}[/tex] which is the negative of the reciprocal of m
Essentially the product of the two slopes = -1
The line
[tex]y = \dfrac{1}{5}x - 19[/tex]
has slope of [tex]\dfrac{1}{5}[/tex] so the slope of line h which is perpendicular to this line must have slope = negative of reciprocal of [tex]\dfrac{1}{5}[/tex]
Reciprocal of [tex]\dfrac{1}{5}[/tex] is 5
Negative of reciprocal is thus -5
Equation of h is of the form
y = -5x + b where b is the y intercept, the value of y at x = 0
Since line h passes through (3, 0) we plug in these values for x and y and solve for b
0 = -5(3) + b
0 = -15 + b
15 = b (Adding 15 on both sides)
b = 15
Equation of line h is y = -5x + 15
Line g is parallel to line h. Parallel lines have the same slope so the equation for line g is
y = -5x + b (since slope of g = slope of h = -5)
Since this line passes through x = -1, y = 15 we can solve for b as before by plugging these values into the equation
15 = -5(-1) + b
15 = 5 + b
10 = b (Subtracting 5 on both sides)
b = 10
So equation of line g = -5x + 10
Tyler has a shoe box in the shape of a right rectangular prism. He is filling the box with cubes that are each 1 cubic inch in order to find the volume of the box. He finds that 48 cubes completely fill the bottom of the box and that he can put 2 more layers of cubes in the box. What is the volume of the box in cubic inches?
The volume of Tyler's shoe box is 144 cubic inch
From the question, we are to calculate the volume of the shoe box.
From the given information, we have that

The point of intersection of the two functions is not on the line y = x; therefore, the functions are not inverses of each other.
The explanation that could be used to verify whether the functions are inverses is; The point of intersection of the two functions is not on the line y = x; therefore, the functions are not inverses of each other.
How to Interpret Function Inverses?
If we assume that (a, b) is a point that lies on both the graph y = f(x) and the graph y = f⁻¹(x), then from the second condition, it follows that the point (b, a) lies on the graph of f.
So, we’re looking for a function whose graph includes two points (a, b) and (b, a) and we want a ≠ b. An example is;
f(x) = -1/x³
So that the inverse function is f⁻¹(x) = 1/x^(1/3)
Thus, applying that concept to this question and we can conclude that the point of intersection of the two functions is not on the line y = x; therefore, the functions are not inverses of each other.

The information about the triangle will be:
Length of the shorter leg: = 5cm
Length of the longer leg: = 12cm
Length of the hypotenuse: = 13cm
How to illustrate the information?It should be noted that the formula for illustrating the information is:
c² = a² + b²
where c = hypothenuse
The shorter leg = x
Longer leg = x + 7
Hypothenuse = 13
Therefore, c² = a² + b²
13² = x² + (x + 7)²
169 = x² + x² + 14x + 49
169 = 2x² + 14x + 49

The expression in factored form for the polynomial of the least possible degree is f(x) = (3 / 16) · (x + 2) · (x + 1) · (x - 2) · (x - 4).
How to write a polynomial in factored form
A polynomial can be written as a product of a constant named lead coefficient and binomials of the form x - r, where r is the root of the polynomial. A root is a value of x such that the polynomial is equal to zero and the lead coefficient can be determined by using the y-intercept of the graph, then:
f(x) = a · (x + 2) · (x + 1) · (x - 2) · (x - 4)
Where a is the lead coefficient.
If we know that f(0) = 3, then the value of the lead coefficient is:
3 = a · (0 + 2) · (0 + 1) · (0 - 2) · (0 - 4)
3 = 16 · a
a = 3 / 16

Find the quotient and the remainder when x- + 5x + 2 is divided by x + 1
Answer: The quotient is when x+ 5x + 2 = 6
The reminder is when x+ 5x + 2 = -4
Step-by-step explanation:
Given data,
The quotient and the remainder when x + 5x + 2 is divided by x + 1
Let, f(x) = x + 5x + 2
g(x) = x+1
we can write,
g(x) = x+1 = 0
g(x) = x = -1
so, f(x) = x + 5x + 2
we can substitute x = -1 value
f(x) = x + 5x + 2
f(-1) = (-1) + 5(-1) + 2
f(-1) = (-1) - 5 + 2
f(-1) = (-1) - 3
f(-1) = -4
Therefore,
The quotient is when x+ 5x + 2 = 6
