Consider the following planes. x + y + z = 3, x + 6y + 6z = 3 (a) Find parametric equations for the line of intersection of the planes. (Use the parameter t.) (b) Find the angle between the planes. (Round your answer to one decimal place.)

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

answer: idk

step-by-step explanation:

1. minimum

2. 6400

3. eight

hope this !

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
