What is the solution to the system of equations y equals 1. 5 x 4?.

The first step in determining whether a linear system is inconsistent is to identify whether the lines are parallel. Check to see if the lines have a y-intercept in common, if so.

This result establishes an inconsistent system due to the fact that two parallel lines with distinct y-intercepts will never intersect.

If there is at least one solution to a linear equations system, it is said to be a consistent system. The system is regarded as inconsistent if there is no solution.

When the lines are parallel to one another, a system of linear equations cannot become inconsistent in any other way. The slope of parallel lines is the same. Therefore, comparing the slopes is a good way to ascertain whether the system is inconsistent. The comparison is simple if the linear equations are written in the point-slope or slope-intercept form. In order to determine the coefficient of x and compare slopes, it is a good idea to solve for y on all equations that are in a different form and express them in the slope-intercept form. The equation system is inconsistent if the slopes are equal to one another.

We can see that he made a total of 30 hot dogs and 15 hamburgers.

We can define the variables:

We know that he cooked a total of 45 dishes, then we can write the equation

x + y = 45

And he cooked twice as many hot dogs as hamburgers, then we can write:

y = 2x

Then we can write a system of equations at:

x + y = 45

y = 2x

We can replace the second equation into the first one, then we have:

x + (2x) = 45

3x = 45

The two adjacent columns that show an interval with an average rate of change of -0.3 are column 7ᵗʰ and 8ᵗʰ.

We have a function used by an architect is designing a water fountain for a park. The function is defined as h(x) = - x²/20 + x + 15

where h(x) --> height of the water jet, in feet,

Also , the average rate of change = - 0.3

Average rate of change is used to measure the change in value of function per unit, on average over an interval. It is derived from the slope line which is formed bu joining the end points of graph. Formula is represented as

A(x) = {F(b) - F(a)}/(b - a)

where b and a are end points of interval.

In this case, this formula is used as

A(x) = {H(x₂) - H(x₁)}/(x₂ - x₁ )

=> -0.3 = {H(x₂) - H(x₁)}/(x₂ - x₁ )

As we see in above figure the difference between the any two values of x is equals to 2 i.e., the final value - initial value = 2 in an interval.

So, x₂ - x₁ = 2

=> -0.3 = {H(x₂) - H(x₁)}/2

=> -0.3× 2 = H(x₂) - H(x₁)

=> -0.6 = H(x₂) - H(x₁)

=> H(x₂) = H(x₁) - 0.6

so, the columns which follows this relationship are the following

The forces acting on a horizontally moving ball in the air are gravity or the force of its own weight, and the force that displaces the ball in the horizontal direction.

Force is an external agent that acts on a body to cause it to move or stop. There are various types of forces, such as magnetic forces, nuclear forces, frictional forces, and so on.

The product of a moving body's mass and acceleration yields force, which is derived from Newton's second law of motion. As a result, as the mass of the object increases, the force required to change its state increases.

The forces acting on a moving ball horizontally are the normal force that displaces it in that direction and the downward force of gravitation equal to its weight. Air resistance acting on the ball can also be considered.

To calculate the number of jars you need to sell to break even, we can use the following formula:

(Cost of materials + Cost of ingredients per jar) / Price per jar = Number of jars needed to break even

We know that the cost of materials is $70, the cost of ingredients per jar is $18 ( $12 for peanuts + $6 for cashews) and the price per jar is $5.

Plugging in these values into the formula we get:

($70 + $18) / $5 = (88/5) = 17.6 jars

So, you need to sell at least 17.6 jars to break even.

--------------------

Cost of materials / (Price per jar - Cost of ingredients per jar) = Number of jars needed to break even

We know that the cost of materials is $70, the cost of ingredients per jar is $18 ( $12 for peanuts + $6 for cashews) and the price per jar is $5.

Plugging in these values into the formula we get:

$70 / ($5 - $18) = 70 / -13 = -5.38 jars

It is not possible to sell -5.38 jars, which means you are making a loss. This indicates that your cost of materials and ingredients is higher than the price you are selling the jars for. To break even, you will have to lower your costs or increase the price of the jars.

The Time Taken to make 20 products = 2hours and 40 minutes = 160 minutes

Time taken to make 10 units = 80 minutes

Time taken to make 30 units = time taken to make 20 units + time taken to make 10 units

The worker needs 4 hours to make 30 units.

The ratio can be calculated as follows:

The first is to convert hours to minutes

2 hours 40 minutes = (2×60)+40 = 120+40 = 160 minutes

The next step is to compare worth comparison

[tex]\frac{a1}{b1}[/tex] = [tex]\frac{a2}{b2}[/tex]

[tex]a_{1} = 160 minutes\\a_{2} = X\\b_{1} = 20 products\\b_{2} = 30 products[/tex]

X = [tex]\frac{(160.30)}{20}[/tex]

X = [tex]\frac{4800}{20}[/tex]
