The solution of the absolute value equation:

|x-2|=|4+x|

is  x = -1

Here we want to solve the following equation:

|x - 2| = |4 + x|

A general absolute value function can be rewritten into two equations, in this case these are:

x - 2 = 4 + x

x - 2 = -(4 + x)

The first one has no solution, but the second one does.

x - 2 = -(4 + x)

x - 2 = -4 -x

2x = -4 + 2

2x = -2

x = -2/2 = -1

That is the solution.

The expression in terms of m and h is D = m/h if the expression is hD = m; the answer is D = m/h.

What exactly is a phrase?

It is described as blending mathematical operators, constants, and variables.

It follows that:

The sentence is:

hD = m

To account for D Declare D as the subject.

As we know, an arithmetic operation can be defined as an operation in which we add, subtract, multiply, and divide integers. It has four basic operators that are +, -, ×, and ÷.

By dividing both sides by h:

hD/h = m/h

Here h ≠ 0

D = m/h

As a result, if the statement is hD = m, then the expression in terms of m and h is D = m/h, and the solution is D = m/h.

Step-by-step explanation:

The value of cos v in simplest terms in fraction form is 17/18

In mathematics, trigonometric functions are real functions that relate an angle of a right-angled triangle to ratios of two side lengths. The six trigonometric functions are Sine, Cosine, Tangent, Secant, Cosecant, and Cotangent.

Given here: The triangle ΔXWV with WV=17 , XV=18,

We know cos ∅= base/hypotenuse

here hypotenuse is XV as it is opposite to the right angle. and the base of the triangle is 17

∴ Cos v=17/18

We can also find the measure of the third angle by using the pythogarean theorm as

Answer: Let x be the fare of the train, and y be the fare of the bus.

We know that:

x + y = 400 (the total fare of the journey)

And, on the return journey the fare of the bus is hiked by a half of what Talia paid initially, so the fare of the bus on the return journey is:

y * 1.5 = y + (y/2)

And the total fare of the return journey is hiked to 4800, so:

x + y + (y/2) = 4800

We can substitute the first equation into the second equation:

x + (y + (y/2)) = 4800

x + y + (y/2) = 4800

x + (y + (y/2)) = 4800

So, we can solve the system of equations by substituting the first equation into the second equation and solving for x.

x + y = 400

x = 4800 - (y + (y/2))

x = 4800 - y - (y/2)

x = 4800 - y - (1/2)y

x = (4800 - y) - (1/2)y

x = 4800 - (3/2)y

Now we have an equation for x in terms of y. To solve for x, we can use the value of y from the first equation

x = 4800 - (3/2)(400)

x = 4800 - 600

x = 4200

So the train fare is 4200 sh

The sheet metal should have a total area of 12.9 x 12.9 = 166.41 square feet.

The sheet metal must be large enough to form a cube with a volume of 300 cubic feet, so the side length of the sheet must be the cube root of 300, which is approximately 6.9 feet. To find the dimensions of the sheet metal, we must take into account the four 3 foot squares that will be removed from each corner. Therefore, the sheet metal should have a length of 6.9 feet + 6 feet (4 times the 3 foot squares) = 12.9 feet and a width of 12.9 feet. This will give the box a volume of 300 cubic feet, and the sheet metal should have a total area of 12.9 x 12.9 = 166.41 square feet.

Here we have to calculate the true proportion of the professor's students who were registered to vote with 95% confidence interval is,

Here we have a random sample of less than 10% of the professor's students with 35 expected successes and 15 expected failures

Here we have know that both of which are at least ten, so a Normal model applies.

Then the value of n = 50,

=> P =35/50 = 0.70

Then the value of q = 1 - p = 1 - 0.70 = 0.30

Then the value of SE is

=> √(0.70 0.30)/ 50 = 0.065

Then with 95% confidence interval is calculated as,

Answer: To obtain a mixture that is 50% orange juice, you must find the amount of 60% orange juice needed to bring the overall concentration of orange juice to 50%.

We can start by using the formula:

(amount of 60% orange juice) / (amount of 60% orange juice + amount of 30% orange juice) = desired concentration

Let's call the amount of 60% orange juice that we need to add x.

So the equation will look like this:

(x) / (x + 5 gallons) = 0.5

We can then solve for x:

x = (0.5 * x + 0.5 * 5 gallons)

x = 2.5 gallons

So, 2.5 gallons of 60% orange juice must be mixed with 5 gallons of 30% orange juice to obtain a mixture that is 50% orange juice.

What is compound interest?

Both the principal and the interest that has accumulated over the previous period are used to compute interest. Compound interest accounts for the principal when calculating the interest for the subsequent month, in contrast to simple interest, which does not. In mathematics, compound interest is frequently denoted by the letter C.I.

We know that formula for compound interest is

[tex]A= P(1 + \frac{r}{n} )^{nt}[/tex]

So, here P = $2658 , n=12, t=5 and r = 0.04
