This question is incomplete, the complete question is;

Find the vector form of the general solution to the given linear system Ax = b; Then use that result to find the vector form of the general solution to Ax = 0.

x1   + x2 + 2x3 = 5

x1            +  x3  = -2

2x1 + x2 +  3x3 = 3

Answer:

the vector form of the general solution to the given linear system Ax = b

x1          -2                -1

x2   =     7         +s    -1

x3          0                 1

find the vector form of the general solution to Ax = 0.

x1                -1

x2   =    s    -1

x3                1

Step-by-step explanation:

Given that;

x1   + x2 + 2x3 = 5

x1            +  x3  = -2

2x1 + x2 +  3x3 = 3

Augmented matrix is expressed as;

1   1    2          5

1   0   3         -2

2  1    3          3

R2 ← R2 - R1        

1   1    2         5

0  -1   -1        -7

2  1    3         3

R3 ← R3 - 2R1

1   1    2         5

0  -1   -1        -7

0  -1   -1        -7

R3 ← R3 - R2

1   1    2         5

0  -1   -1        -7

0  0   0        0

R1 ← R1 + R2

1   0   1         -2

0  -1   -1        -7

0  0   0        0

R2 ← - R2

1   0   1         -2

0  1    1         7

0  0   0        0

SO from the above reduced matrix, we get

x1 = -2 - x3

x2 = 7 - x3

x3 = x3

now we introduce parameter "s" for free variable x3

x1 = -2 - s

x2 = 7 - s

x3 = s

x1          -2                -1

x2   =     7         +s    -1

x3          0                 1

General solution of Ax = 0 will be

x1                -1

x2   =    s    -1

x3                1

Answer:

All real numbers are solutions

Step-by-step explanation:

10(x + 1/2) = 3x + 5 + 7x

~Distribute left side

10x + 5 = 3x + 5 + 7x

~Combine like terms

10x + 5 = 10x + 5

~Subtract 5 to both sides

10x = 10x

~Divide 10 to both sides

x = x

~Subtract x to both sides

0 = 0

Answer:

The answer is below

Step-by-step explanation:

Let us assume the angle is -π/4.

Coterminal angles are angles that have the same initial side and terminal side. They are angles in standard position (angles with the initial side on the positive x -axis) that have a common terminal side.

Positive coterminal angles are gotten by adding 360° if the angle is in degrees or 2π for angles in radian while negative coterminal angles are gotten by subtracting 360° if the angle is in degrees or 2π for angles in radian.

Positive coterminal angle = -π/4 + 2π = 7π/4, 7π/4 + 2π = 15π/4

Positive coterminal angle = 7π/4, 15π/4

Negative coterminal angle = -π/4 - 2π = -9π/4, -9π/4 - 2π = -17π/4

Negative coterminal angle = -9π/4, -17π/4

Answer:

P(x≤14) = 0.556

Step-by-step explanation:

Given:

Probability of throwing a strike (p) = 0.487

Total number of throw (n) = 29

Find:

Probability that no more than 14 of them are strikes P(x≤14)

Computation:

Mean(np) = (29)(0.487)

Mean(np) = 14.123

Standard deviation = √[mean( 1- p)]

Standard deviation = √[14.123( 1 - 0.487)]

Standard deviation = 2.6917  (Approx)

P(X < x) = P[(Z < (x - mean)]/[Standard deviation])

P(x≤14) = P(Z < (14.5 - 14.123) / 2.6917 )

P(x≤14) = 0.556

The solution of the expression is (55z + 6 ) / 20.

Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication and division.

Given that the expression is 3/4(z+2/5)+2z. The expression will be solved as below,

E = 3/4(z+2/5)+2z

E = 3/4( z + 2 / 5 ) + 2z

E = 3/4 ( 5z + 2) / 5 + 2z

E = ( 15z + 6 + 40z ) /20

E = (55z + 6 ) / 20

Therefore, the solution of the expression is (55z + 6 ) / 20.

A function f (x) and g (x) then:

(f + g) (x) = x² - x + 6

Further explanation

Like the number operations we do in real numbers, operations such as addition, installation, division or multiplication can also be done on two functions.

Suppose a function f (x) and g (x) then:

(f + g) (x) = f (x) + g (x)

(f + g) (x) is a new function of the sum of f (x) and g (x)

Likewise with other function operations:

(f-g) (x) = f (x) - g (x)

(fg) (x) = f (x) x g (x)

(f / g) (x) = f (x) / g (x)

In addition to the above operations we can combine two functions using the function composition with the symbol o

(fog) (x) = f ((g (x))

Known on the question

f (x) = x² + 1

g (x) = 5 x

Summing the two functions f (x) and g (x):

(f + g) (x) = f (x) + g (x)

(f + g) (x) = x² + 1 + 5 - x

(f + g) (x) = x² - x + 6
