Group Title
Engineers use threedimensional coordinates to design construction projects. An overhead light is anchored at point (7, 12, 10) in a design where the floor of the building is represented by the twodimensional coordinate plane (xaxis and yaxis). Measurements are in feet.
1. Lights are spaced from the hanging light, 4 feet away in the xdirection and 4 feet in the ydirection. Select the possible coordinates of the anchors for two other lights.
a. (3, 8, 10) and (11, 16, 10)
b. (3, 8, 6) and (11, 16, 14)
c. (3, 12, 10) and (11, 12, 10)
d. (7, 8, 10) and (7, 16, 10)

I think, in the answer, 10 should be the number for z in (x,y,z), because the height of the ceiling remains constant. so I think what you're looking for, is two other lights that are 4 feet away in x and y, but still at 10 for z

so like x has to be four away from y???

no. think of x and y as independent. the directions say we want lights that are 4 feet away in x, and 4 feet away in y, but constant at 10 in z. so if we have one light at the point (7,12,10), where can we put more lights?

ooooh, so itll be 11, 16. 10?

that's one of them. we can also go the other way and say we want a light at (3,8,10) since that meets our requirements too

The roof lines of a building can be described by the system of equations below, where the floor is represented by the xaxis and the yaxis and the height of the building is along the zaxis. Measurements are in feet.

i go to online school so it's kinda like they just give you a problem and you have to solve it on your own....

I think you should probably put this into another question for other people to help you with  I can't remmeber quite how to do this the algebra 2 way
