How many solutions for x does the following equation have? 2(x + 4) − 1 = 2x + 7

4vir4ik [10]

Answer:

The equation has infinity solutions

Step-by-step explanation:

we have

$2(x+4)-1=2x+7$

Applying distributive property left side

$2x+8-1=2x+7$

Combine like terms

$2x+7=2x+7$

The linear equation of the left side is equal to the linear equation of the right side

Both lines are identical

therefore

Is a consistent dependent system

The equation has infinity solutions

Consider a triangle formed by connecting the three points: (0 0 0), (1 0 0), (1 1 1). a. Find the vector which is perpendicular

Sidana [21]

Answer:

=k−j or (0 -1 1)

Step-by-step explanation:

The Vector or Outer Product two vectors, say →x&→y, is

denoted by →x×→y, is a perpendicular vector to the plane containing them.

The given pts. A (0 0 0), B (1 0 0), C (1 1 1) lie in a

plane ABC.

As suchType equation here., the vectors (→(AB ) )and (→AC ) are members, ∈ of the plane ABC

That is □(→(AB )×(→AC)) to the plane ABC

(→(AB ) )=(1-0,0-0,0-0)=(1,0,0)

(→(AC ) )=(1-0,1-0,1-0)=(1,1,1)

(→(AB )×(→AC= (0i -j k)

=k−j

Which is in the positive Z direction

Gnom [1K]

Answer:

1. about 7.87 feet away

2. About 8.37 yds

Step-by-step explanation:

1. a^2+b^2=c^2

so 25+37= C^2

= 62

Square root of 62 = 7.87400787401

(About 7.87 ft away)

2. 40+30 = C^2

Square root of 70 = 8.36660026534

About 8.37
