Without graphing, classify each system of equations as independent, dependent, or inconsistent. Solve independent systems by graphing.1) 5 - y = 2x
6x - 15 = -3y

2) 6y + 2x = 8
12y + 4x = 4

Answers

The correct classification of the given equations is as follows:

First equation is dependent
Second equation is inconsistent

What is a Dependent Equation?

This refers to the system of equations where an equation has infinite solutions and has more than one form on a given line.

With this in mind, we can see that when we are given a system of equations such as

5 - y = 2x

6x - 15 = -3y, then we know that this is a dependent equation because of the infinite solutions on the two equations.

What is the solution to the system of equations?

(10, –20)
(10, 4)
(4, 10

Answers

Answer:

The correct option is 2.

Step-by-step explanation:

The given system of equations is

$y=-5x+30$ .... (1)

$x=10$ ..... (2)

Substitute the value of x from equation (2), in equation (1).

$y=-5(10)+30$

On simplification, we get

$y=-50+30$

$y=-20$

The value of xis 10 and the value of y is -20. So, the solution of the given system of equation is (10,-20).

Therefore the correct option is 2.

The second statement is correct.

The sum of a number and seven times of it is equal to the product of 25.6 and 12.5. What will be one fourth of that number?

Answers

Answer:

x + 7x = (25.6)(12.5)

8x = 320

x = 40, so (1/4)(40) = 10
