Let P be the plane that intersects
- x-axis at point (-5,0,0);
- y-axis at point (0,-2,0);
- z-axis at point (0,0,5).
Write the equation of the plane P:

Then

The coefficients at variables x, y and z are the coordinates of perpendicular vector to the plane. Thus

Answer: 
Midpoint = (8-5),(-3-9) / 2
= (3,-12)/2
= (3/2,-6)
Answer:
Step-by-step explanation:
Since triangle ADE and triangle ABC are similar, that means their sides are proportional, thus we get the equation



Thus the value of x is 4
Answer:
D. x = 7
Step-by-step explanation:
The labeled angles are the acute angles of a right triangle, so they are complementary. Their measures add up to 90 deg.
8x + 7 + 3x + 6 = 90
11x + 13 = 90
11x = 77
x = 7
Answer:
$6
Step-by-step explanation:
p=pound
5/6p= 500
p= 500(6/5)
p=600 cents
p=$6
