Answer:
2x + 3y + 5z = 9
Step-by-step explanation:
The normal defines all the planes perpendicular to that vector. To isolate to a single plane, just apply the known point.
ax + by + cz = d
2x + 3y + 5z = d
2(1) + 3(-1) + 5(2) = 9
Answer:
Domain: -∞≤x≤∞
Range: 0≤F(x)≤∞
Step-by-step explanation:
The x variable can take any value.
In the case of F(x), the function only can take positive values, due to the absolute value function, and the function does not have any other restriction.
Answer:
12 male teachers
Step-by-step explanation:
If the ratio is 3:4, and the number of female teachers is 16, then the number of male teachers must be 12. This can be confirmed by multiplying both 3 and 4 by 4, or 12/16 = 3/4.
The answer would be 4/5 and 40%
