Solve the inequality.
Mars2501 [29]
To solve an inequality, get the variable you're solving for on one side of the inequality and everything else on the opposite side.

\frac{2}{5}  \geq x - \frac{4}{5}

You get the x variable on it's own by undoing the operations done to it.

For example, if x is being multiplied by 5, you undo the multiplication operation by using the inverse of multiplication. Which is division.

We need to add \frac{4}{5} to both sides of the inequality to undo the subtraction operation done to x.

\frac{2}{5} + \frac{4}{5}  \geq x - \frac{4}{5} + \frac{4}{5} \\ \\ \frac{6}{5}  \geq x

Convert the improper fraction into a mixed number.

\frac{6}{5} = 1 \frac{1}{5}

So, D 1 1/5 ≥ x is the answer.

The following two vectors satisfy the same system of linear equations. u=⎡⎣⎢⎢6−5−5⎤⎦⎥⎥, v=⎡⎣⎢⎢746⎤⎦⎥⎥ Find x and y that make the
kondaur [170]

Answer:

x=-30/71, y=0

Step-by-step explanation:

if a vector satisfies an equation of the form ax+by+cz=0 then the vector is  

parallel to the plane ax+by+cz=0, and, the cross product of two vectors results in an orthogonal vector to both.

So, <a,b,c> the normal vector of the plane ax+by+cz=0, can be found as the cross product of the two parallel vetors to the plane:

<a,b,c> = <6,-5,-5>×<7,4,6>= <-10,-71,59>

so, the homogeneous system is:

-10x-71y+59z=0

by replacing the vector <3,x,y> in the system

-30-71x+59y=0

So, there are 2 unknown variables and 1 equation, it means that 1 variable is free

so, y=0 is a random defition and x can be obtain with the equation

-30-71x=0 -> x=-30/71
