Equation of this line is K = -2J + 28

Step-by-step explanation:

Step 1:

The equation can be written in slope intercept form which is y = mx + b

Step 2:

Calculate slope of the line, m = (y2 - y1)/(x2 - x1)

⇒ m = (24 - 20)/(2 - 4) = 4/-2) = -2

Step 3:

Find y-intercept of the line

⇒ b = 28

Step 4:

Substitute values in the equation

⇒ K = -2J + 28

Solve the following system of equations. State whether the system is consistent and independent, consistent and dependent, or in

Makovka662 [10]

Answer:

Inconsistent

Step-by-step explanation:

If a system has at least one solution, it is said to be consistent.

If a consistent system has exactly one solution, it is independent.

If a consistent system has an infinite number of solutions, it is dependent.

A system of equations is called an inconsistent system of equations if there is no solution.

Given the system of two equations

$\left\{\begin{array}{l}-4x+7y=28\\ \\4x-7y=32\end{array}\right.$

Add these two equations:

$(-4x+7y)+(4x-7y)=28+32\\ \\-4x+7y+4x-7y=60\\ \\(-4x+4x)+(7y-7y)=60\\ \\0=60$

This is false statement, hence, the system of two equations has no solution and is inconsistent.

Which statement about the values 0.034 and 3.40 are true

Nana76 [90]

Answer:

See Explanation

Step-by-step explanation:

This question requires options.

Since none is provided, I will give a general solution.

We have: 0.034 and 3.40

Required

The relationship between them

3.40 can be expressed as:

$3.40 \to 0.034 * 100$

This means that 3.40 is 100 of 0.034

Similarly, 0.034 can be expressed as:

$0.034 \to 3.40 * \frac{1}{100}$

This means that 0.034 is 1/100 of 3.40
