It’s about unit vector
Find the unit vector in the direction of the given vector v= <4,8>

<⅕√5, ⅖√5>

Step-by-step explanation:

First, find the magnitude of the vector.

√(4² + 8²) = 4√5

Divide the vector by the magnitude.

<4, 8> / 4√5 = <1/√5, 2/√5>

If desired, rationalize.

<⅕√5, ⅖√5>

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
