[Systems of equations] (/20) 1. Suppose the coefficient matrix of a system of linear equations has a pivot position in every row
Marina86 [1]

Answer:

The system is consistent because the rightmost column of the augmented matrix is not a pivot column.

Step-by-step explanation:

It is given that the coefficient of the matrix of a linear equation has a pivot position in every row.

It is provided by the Existence and Uniqueness theorem that linear system is said to be consistent when only  the column in the rightmost of the matrix which is augmented is not a pivot column.

When the linear system is considered consistent, then every solution set consists of either unique solution where there will be no any variables which are free or infinitely many solutions, when there is at least one free variable. This explains why the system is consistent.

For any m x n augmented matrix of any system, if its co-efficient matrix has a pivot position in every row, then there will never be a row of the form [0 .... 0 b].

Convert the following percent into common fractions in simplest form:<br> 5 1/3%
Tomtit [17]

Answer:

4/75

Step-by-step explanation:

you will get 5 and 1/3 percent equals (5 + 1/3) / 100 which is equal to 5/100 + (1/3) / 100 which is equal to 5/100 + 1/300. place both fractions under a common denominator. you will get 5/100 + 1/300 = 15/300 + 1/300 = 16/300. simplify the fraction to get 16/300 = 8/150 = 4/75

1 rectangle has a circumference of 72cm. If you reduce the width by 6cm and keep the same length, the area will decrease by 120c
WARRIOR [948]

Answer

the length is 20 cm and breadth is 16cm

Step-by-step explanation:

let, 2(a+b)= 72( as its the formulae of circumference)

here a is the length and b is the breadth

now total area is ab

according to the question

a(b-6)= ab-120

or -6a= - 120

so length is 20 cm

now by putting the value in the 1st eq we get

2(a+b)=72

or(a+b)=36

or 20+b=36

so breadth is 16 cm.

length is 20cm and breadth is 16 cm

(u can verify that easily)

thank u

What is the approximate distance between points D and E? Round your answer to the nearest hundredth.
Usimov [2.4K]

Answer:

C.8.12 units  

Step-by-step explanation:

Given the coordinates of two points:

P1=(x_1,y_1)\\P2=(x_2,y_2)

The distance between these points is determined by the following equation:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

We can extract the exact coordinates from the graph provided by the problem:

P1=D=(x_1,y_1)=(-4,-1)\\P2=E=(x_2,y_2)=(4,-3)

Therefore:

d=\sqrt{(4-(-4))^2+(-3-(-1))^2} =\sqrt{(8)^2+(-2)^2} =\sqrt{64+4} =\sqrt{68} \\\\d=8.246211251

I don't see the correct answer from the choices given. So I would say the most aproximate is C.
