3. Let P, be the plane through the origin containing the vectors [1, 2, -1] and [0, 1, 1]. Let P2 be the plane through the point (1, 1, 1) parallel to the vectors (-1, 2, 2] and [3,4,-2].

(a) Find an equation for Pin normal form ax + by + cz = 0.

(b) The planes P, and P2 intersect in a line. Find a parametric equation for this line.

no

step-by-step explanation:

2-7=-5

7-2=5

when you combing like terms for ech expression, 5 and -5. these numbers are not equal to each other.

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )
