Find an equation of the plane through the point (−5,−1,2) with normal vector =⟨−1,−5,2⟩.

Step-by-step explanation:

A plane that passes through the point with a normal vector of has the following equation, initially:

After we solve this, we have

In this problem, we have that:

So

Multplying everything by -1

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5

step-by-step explanation:

the correct answer is you spend $55.78 more in a brand store that buy ing in a normal store.

step-by-step explanation:

brand = spend   $ 135.85 total

store = spend $80.07 total
