After solving the linear system of equations given, the result shows it has infinitely many solutions.

In mathematics, a collection of two or more linear equations containing the same variables is referred to as a system of linear equations. Here, one might say that linear equations are those of the first order, where the maximum power of the variable is 1. One variable, two variables, or three variables can all be included in a linear equation.

Systems of equations known as linear systems are those in which the variables are always multiplied solely by constants before being added together. Both static and dynamic relationships between variables are described by linear systems.

5x - y = 15 ...............(1)

-10x+2y=-30 ................ (2)

Now, multiply (1) by 2

10x - 2y = 30 ................. (3)

now, add the equation (2) from (3) we get

10x - 2y = 30

-10x + 2y = -30

0 = 0

that means we get infinitely many solutions.

The slope of the given line passing through the points ( -2 ,7 ) and ( 4, 9 ) is given by ( 1 /3 ).

As given in the question,

Given line passes through the points :

( x₁ , y₁ ) = ( -2 ,7 )

( x₂ , y₂ ) = ( 4, 9 )

Standard formula to calculate the slope of the line passing through two coordinates is :

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substitute the value of the given points we get,

Slope = ( 9 - 7 ) / ( 4 - ( -2 ) )

⇒ Slope = 2 / 6

⇒ Slope = 1 / 3

Therefore, the required slope of the line passing through the given points is equal to ( 1 / 3 ) .

105 joule/second is the power generated in a body moving at a velocity of 15m/s with a force of 7N in 2s​

The word "force" has a specific meaning in science. At this level, calling a force a push or a pull is entirely appropriate. A force is not something an object "has in it" or that it "contains." One thing experiences a force from another. There is no distinction between living and non-living things in the concept of a force.

Given, a body moving at a velocity of 15m/s with a force of 7N in 2s​

From the general formula of Power

Power = force * velocity

In our case

force = 7N

velocity = 15 m/s

Thus,

Power = 7 * 15 Nm/s

Power generated in body = 105 Nm/s or joule/s

Therefore, the power generated in a body moving at a velocity of 15m/s with a force of 7N in 2s​ is 105 joule/second.

The other two angles in an obtuse angled triangle are acute because one of them is greater than 90 degrees and the other two are less than 90 degrees.

Any triangle with an interior angle greater than 90 degrees is said to have an obtuse angle. The sum of the other two angles in an obtuse triangle is less than 90° if one angle in the triangle is greater than 90°.

Obtuseness can never exist in an equilateral triangle. Each of the equal sides and angles in an equilateral triangle measures 60°, making them all sharp. Because of this, an equilateral angle can never be acutely inclined.

Aaron's weight is $118$ pounds - $54$ pounds = $64$ pounds more than Levi's weight.

Weight is a measure of the gravitational force of attraction between an object and the Earth, or between two objects. It is measured in Newtons (N) or kilograms (kg). Weight is created by the force of gravity that pulls objects toward the center of the Earth. The greater the mass of an object, the greater the force of gravity and thus the greater its weight. Weight is an important factor in determining the motion of an object and its interaction with other objects.

Aaron's weight is $10$ pounds more than twice Levi's weight, so Levi's weight is $\frac{1}{2}(118 - 10) = 54$ pounds. This means that Aaron's weight is $118$ pounds - $54$ pounds = $64$ pounds more than Levi's weight.

The correct answer is B. $1,000. According to a survey conducted by Bankrate in 2019, 48% of Americans reported having less than $1,000 in savings.

This can be calculated using the following formula:

Percentage of Americans with less than $1,000 in savings = (Number of Americans with less than $1,000 in savings / Total number of Americans surveyed) x 100

Using the data from the survey, the formula can be expressed as follows:

Percentage of Americans with less than $1,000 in savings = (11,094 / 23,064) x 100 = 48.1%

b) After 6 years the value of the equipment will be $31886.46.

c) The price of the equipment will be half of its original price after 6.6 years.

What is an exponential function?

The formula for an exponential function is f(x) = a^x, where x is a variable and a is a constant that serves as the function's base and must be bigger than 0.

The price of weaving equipment = $60000.

The depreciation rate per year = 10%

The depreciation value will be -

= (1 - 10%)

= 1 - (10/100)

= 1 - 0.10

= 0.9

Let the time in years be measured in t.

The equation for value after t years will be -

V(t) = 60000(0.9)^t

This is an exponential equation.

To find the value of equipment 6 years after purchase, substitute the value of t = 6.

V(t) = 60000(0.9)^t

V = 60000(0.9)^6

V = 60000 × 0.531441

V = 31886.46

Therefore, the value of equipment will be $31886.46.

To find the time at which the value of the equipment will be half its price, substitute the value of V(t) = 30000.

V(t) = 60000(0.9)^t

30000 = 60000(0.9)^t

(0.9)^t = 60000/30000

(0.9)^t = 2

t ln (0.9) = ln (2)

t =  ln (2)/ln (0.9)

t = 0.301/0.0457

t = 6.58 ≈ 6.6

Therefore, after 6.6 years the value of the equipment will be $30000.

What is decimal numbers?

A fraction with a power of 10 as the denominator is known as a decimal number. For instance, the decimal equivalent of the fraction 4/10 is 0.4. The decimal point is the dot found in decimal figures. The fraction's numerator, or fractional component, is indicated by the number to the right of the decimal point.

We align the decimal points for addition and subtraction so that the decimal and whole number components are aligned.

The only difference between multiplying decimals and multiplying whole numbers is where the decimal point appears in the solution.

In order for the number of decimal places in the product to equal the sum of the decimal places in the factors, the decimal point must be inserted in the product when multiplying decimals.

The formula of v is equal to the ratio of 10u to (u+10) that is 10u/(u+10).

The given formula is an equation that relates two variables, u and v, in an experiment on lenses. The equation states that the ratio of (u - v) to (uv) is equal to 1/10.

That is,

u-v / uv = 1/10

To solve for v, we can use algebraic manipulation techniques. By multiplying both sides of the equation by (uv), we get

(u - v) = (uv) / 10.

Then, by adding v to both sides, we get,

u = v + (uv) / 10

u = v (1 + u/10)

10u = v (u+10)
