Answer:

The equation of plane is

22x -3y+18z = 21

Step-by-step explanation:

We have to find the equation of plane passing through the point (0,-1,1) and orthogonal to the planes

n_1:3x + 4y-3z = 0\\n_2:-3x + 2y + 4z = 5

Thus, we can write:

n_1:\\n_2:

We will evaluate:

n = n_1\times n_2\\\\n = \left[\begin{array}{ccc}i&j&k\\3&4&-3\\-3&2&4\end{array}\right] \\\\n = i(16 + 6)-j(12-9) +k(6+12)\\n = 22i-3j+18k\\n =

The required plane passes through the point (0,-1,1)

Thus, the equation of plane is

n.=0\\\Rightarrow .=0\\\Rightarrow 22(x) -3(y+1) + 18(z-1) =0\\\Rightarrow 22x - 3y - 3 + 18z - 18 = 0\\\Rightarrow 22x -3y+18z = 21

is the required equation of the plane.

How to divide fractions
Anna [14]

First leave the first fraction alone.

Then turn the division sign into a multiplication sign.

Flip the second fraction over ( find its reciprocal ).

Multiply the numerators of the two fractions together. This result will be the numerator ( the top part ) of your answer.

Multiply the denominators of the two fractions together. The result will be the denominator ( the bottom part ) of your answer.

Then simplify your fraction by reducing it to the simplest terms.
