Therefore , the value of the given problem of linear equation comes out to be  x = -250.

In algebra, a mathematical model is just one that of the form y=mx+b. The slope is B, and the y-intercept is m. Since x and y are variables, the previous sentence is frequently referred to as a "mathematical expression with 2 variables." Bivariate linear equations are linear equations with two variables. Linear equations can be found in many different situations. Once an issue has the formula y=mx+b, where m denotes the slope and b the y-intercept, it is said to be linear.

Here,

Given : 70.50 - 45.50 + 0.15x - 0.09x =0

To find the value of x,

Thus,

We do : 70.50 - 45.50 + 0.15x - 0.09x =0

=> 15 + 0.06x =0

=> 6/100 *x = -15

=> 6x = -1500

=> x = -1500/6

=> x = -250

Therefore , the value of the given problem of linear equation comes out to be  x = -250.

Answer: 12...12...12...57

Answer:

Step-by-step explanation:

Attached are the formula. (Ignore the point slope formula not needed)

For second part, just know that m= slope and b = y intercept in the slope-intercept formula. Just plug those in for each of those, I will do one for you and you try the rest ok

Slope = 1/3 and y-intercept = -1

Slope intercept formula is y = mx + b

y = 1/3 x + (-1)

y= 1/3 x -1

Now you try the rest.

The z-score corresponding to an observation of 470 is -0.97.

Given that the observation x is 470.

mean, is 570

standard deviation, σ is 103

For the occurrence score,

z = (x - μ)/σ

z = (470 - 570)/103

z = -0.97

The standard score in statistics is the amount of standard deviations that a raw score (i.e., an observed value or data point) deviates from or exceeds the mean of the thing being observed or measured. Standard scores are positive for raw scores above the mean and negative for raw scores below the mean.

It is determined by deducting the population mean from a given raw score, then dividing the result by the population standard deviation. Standardizing or normalizing is the process of transforming a raw score into a standard score (however, "normalizing" can refer to many types of ratios; see normalization for more).

According to the linear cost function sneakers are produced in 8 hours is 4400.

Businesses employ a mathematical technique called a linear cost function to calculate the overall costs related to a certain level of production. When the cost of producing each item is constant regardless of the number of units produced, this approach of cost estimating can be used.

Given :

C(x) = 25x + 400

x(t) = 20t

∴ C(x) = 25(20t) + 400

∴ C(x) = 500t + 400

Now,

C(x(t)) =  C(x(8)) = 500t + 400

                         = 500(8) + 400

                         = 4400

∴   C(x(8)) =4400

In a 1000g sample, 250g will be left undecayed and still radioactive after 11,400 years.

The amount of time needed for a quantity (of substance) to decrease to half of its initial value is known as the half-life (symbol t12). In nuclear physics, the phrase is frequently used to indicate how rapidly unstable atoms decay radioactively or how long stable atoms last. The phrase is also used more broadly to describe any kind of exponential decay (or, very infrequently, nonexponential decay). The biological half-life of medications and other compounds in the human body, for instance, is a term used in the medical sciences. Half-opposite of life's exponential growth is time's doubling.

Carbon-14 has a half-life of approximately 5700 years, which means that after 5700 years, half of the original amount of Carbon-14 will remain undecayed and still radioactive. After 11,400 years, there will be 1/4 of the original amount remaining, because two half-lives have passed. So, in a 1000g sample, 250g will be left undecayed and still radioactive after 11,400 years.

Given functions are inverse of each other.

What are inverse functions?

A function that reverses the effects of another function is called an inverse function. When y=f(x) and x=g, a function g is the inverse of a function f. (y). Applying f and then g is equivalent to doing nothing, in other words. This can be expressed as g(f(x))=x in terms of the relationship between f and g.

Here, we have

Given: f(x) = 5x + 2

g(x) = (x-2)/5

We have to inverse one another function.

f(x) = 5x + 2

g(x) = (x-2)/5

f(g(x)) = f( (x-2)/5)

f(g(x)) = 5×(x-2)/5 + 2

f(g(x)) = x - 2 + 2

f(g(x)) = x these functions are inverse of each other.

No, an equilateral triangle is not similar to a scalene triangle.

Two triangles are similar if they have the same shape, but they can be different sizes. In order for two triangles to be similar, the angles in the triangles must be congruent (equal in measure) and the sides of the triangles must be proportional. An equilateral triangle has three congruent angles, each measuring 60 degrees, and three congruent sides. A scalene triangle, on the other hand, has three sides that are all different lengths and three angles that are all different measures. Because the angles and sides of an equilateral triangle are not proportional to the sides and angles of a scalene triangle, the two triangles are not similar.

Step-by-step explanation:

- 5y = 10 - 5x → (1)

- 2y = 8 - 4x → (2)

multiplying (1) by - 2 and (2) by 5 and adding will eliminate y

10y = - - 20 + 10x → (3)

- 10y = 40 - 20x → (4)

add (3) and (4) term by term to eliminate y

0 = 20 - 10x ( add 10x to both sides )

10x = 20 ( divide both sides by 10 )

x = 2

substitute x = 2 into either of the 2 equations and solve for y

substituting into (1)

- 5y = 10 - 5(2)

- 5y = 10 - 10 = 0 , then

y = 0

The horizontal asymptote is y = 0 because m = n. A function's graph has a line known as a horizontal asymptote.

A horizontal asymptote is a line that the graph of a function approaches as x tends to either positive or negative infinity. If the degree of the numerator is equal to the degree of the denominator, then the horizontal asymptote of the function is the line y = a/b, whereThe leading coefficients in the denominator and numerator, respectively, are a and b. Therefore, if m = n, then the horizontal asymptote is y = a/b, which reduces to y = 0.

The statement that defines the horizontal asymptote is that if m = n, then the horizontal asymptote is y = 0.
